CrossCurve MetaLayer is an orchestration layer built on top of liquidity routes.

Instead of providing access to a single DEX, bridge, or aggregator, MetaLayer operates one level higher - it connects multiple liquidity sources and execution systems into a unified routing layer. This allows CrossCurve to construct multi-step, cross-protocol, and cross-chain execution paths that are not available through direct integrations with individual protocols.

MetaLayer aggregates:

• DEXs

• Aggregators

• Token bridges

and orchestrates them into optimized execution flows. A single route may include several sequential steps - for example, a swap via one DEX, followed by a bridge, and finalized by another aggregator on the destination network.

As a result, MetaLayer enables execution efficiency that cannot be achieved by standalone protocols.

The CrossCurve MetaLayer ecosystem consists of multiple products that can operate independently, but together form a composable system capable of solving complex liquidity routing problems through a single integration.

Why CrossCurve MetaLayer?

For Integrators

Integrating liquidity across multiple chains traditionally requires:

• Maintaining N direct integrations with DEXs, bridges, and aggregators

• Constantly updating routing logic as new protocols and paths emerge

• Manually handling cross-chain execution and failure scenarios

• Missing optimal execution paths due to fragmented infrastructure

The most critical pain point is the operational and engineering cost of maintaining multiple integrations.

CrossCurve MetaLayer replaces this complexity with a single integration.

By integrating once with the MetaLayer API, an integrator gains:

• Access to all supported liquidity routes and their combinations

• Automatic discovery of optimal execution paths

• Reduced engineering overhead and lower maintenance costs

• Faster time-to-market for Integrators

• Seamless scalability as new protocols and networks are added

One integration unlocks all current and future routes - something that is fundamentally impossible with direct, protocol-level integrations.

For Blockchains

For blockchains, access to global liquidity usually requires significant upfront investment:

• Incentivizing liquidity providers

or

• Bootstrapping bridges with protocol-owned liquidity

With CrossCurve MetaLayer, blockchains can connect their native assets to the broader crypto market without allocating capital to liquidity bootstrap.

This means:

• No need to incentivize LPs

• No need to deploy a DEX to enable cross-chain swaps

• No need to lock liquidity into bridge pools

Through MetaLayer, a blockchain gains frictionless access to external liquidity flows, enabling inflow of TVL from the broader crypto ecosystem. This lowers entry barriers for users and developers, improves UX, and supports organic ecosystem growth.

CrossCurve Ecosystem Products

CrossCurve MetaLayer is implemented through a set of composable products. Each product can be used independently, but together they form a unified orchestration system.

MetaLayer API

The primary integration point for developers and integrators.

Provides programmatic access to all supported liquidity routes and their combinations through a single API.

CrossCurve Token Bridge

The CrossCurve Token Bridge (ex Eywa Token Bridge ) is an infrastructure solution designed for the fluid movement of assets across multiple blockchains.

By integrating aggregation through the CrossCurve Metalayer, projects unlock Any-to-Any exchange capabilities (any token for any token).

CrossCurve Oracle Network

The CrossCurve Oracle Network (ex Eywa Oracle Network) is a decentralized cross-chain messaging service. It provides a robust solution for clients who require seamless communication between different blockchains but want to avoid the high costs and lengthy development cycles associated with building a proprietary messaging infrastructure. By leveraging CrossCurve’s pre-built oracle network, projects can focus on their core logic while ensuring secure and rapid data transmission across chains.

Consensus Bridge

CrossCurve Consensus Bridge is a high-security messaging service that utilizes multi-protocol validation. A message is only delivered to the recipient once it has been independently confirmed by several different messaging protocols, effectively eliminating any single point of failure.

This product is purpose-built for projects with stringent security requirements looking to mitigate the risks of cross-chain infrastructure exploits. If the compromise of a single messaging protocol poses an unacceptable risk to your business model, the Consensus Bridge provides the necessary resilience and peace of mind.

CrossCurve App

A user-facing application that demonstrates MetaLayer capabilities through a unified UX, showcasing how complex routes can be abstracted into simple user interactions.

Summary

CrossCurve MetaLayer is not a single protocol or a simple aggregator. It is an orchestration layer that turns fragmented liquidity infrastructure into a unified execution system.

For integrators, it replaces many integrations with one. For blockchains, it opens access to global liquidity without capital-intensive bootstrapping. For the ecosystem, it enables liquidity to flow freely across chains and protocols.

The CrossCurve Consensus Bridge addresses one of the key problems of modern cross-chain solutions — the vulnerability of bridges and the so-called “black swan” risk. A prime example of such a risk is the Multichain incident, after which Curve DAO withdrew its trust from bridges based on centralized governance.

The core issue lies in the fact that most existing bridges are controlled by a limited group of participants — validators or members of multisig groups. This makes them vulnerable and unstable. Classic examples of such failures include hacks or loss of funds in protocols such as Multichain, PolyNetwork, Wormhole, Nomad and Ronin.

Unlike the traditional PoA (proof-of-authority) solutions, the CrossCurve Consensus Bridge uses a validation model based on agreement between independent data transmission protocols. This architecture involves Axelar, LayerZero, Router Protocol, Asterizm and Chainlink CCIP. A transaction is completed only if consensus is reached among multiple sources. If the data diverges, the transaction is automatically rejected, preventing potential compromise and ensuring the safety of user funds.

How it works:

• The user's assets are locked in the consensus bridge smart contract on the source network.

• Transaction data is transmitted through multiple protocols simultaneously, and the smart contract of the target network verifies their consistency.

• If consensus is reached, the transaction is finalized; otherwise, the funds are returned to the user.

Advantages:

• Security: The risk of compromise is minimized thanks to consensus among several protocols — the likelihood of all protocols being hacked at the same time is virtually zero.

• Decentralization: Bridge security does not depend on individual teams; the bridge smart contracts are governed by CrossCurve DAO, and the protocol’s liquidity is fully controlled by users.

• Versatility: The consensus bridge supports the transmission of both tokens and data, making it a universal tool for cross-chain applications.

Consensus Bridge is not just a bridge—it is the transport layer of the CrossCurve Metalayer, providing a reliable connection between blockchains. It enables developers and users to safely transfer assets, data, and liquidity, forming the foundation for a scalable and resilient cross-chain ecosystem of the future.

The CrossCurve Token Bridge lets projects present their token on other networks by locking their assets in smart contracts and issuing the token’s derivative on other networks. Our bridge allows you to move issued derivatives between blockchains in all directions, without having to return to the original token lock network using Cross-chain Data Protocol (CDP).

Regardless of the differences among protocols, rules specifications and governance mechanics of these networks, a usage of the CrossCurve Token Bridge makes it possible for users to move assets among these chains in a reliable and secure way.

Mechanics

The CrossCurve Token Bridge consists of the Portal and Synthesis smart contracts deployed in each of the Blockchains: 1, 2, 3, and uses the CrossCurve Cross-chain Data Protocol (CDP) to transfer cross-chain calls between them.

To move assets across Blockchains, the CrossCurve Token Bridge uses synthetic assets (s-tokens). S-tokens are created when someone needs to transfer an asset between two blockchains.

Example: Native Token Bridging

When transferring token X, the bridge uses a Lock-Mint-Burn-Unlock mechanism. The original X token is locked in the Portal smart contract on Blockchain 1. This transaction triggers an event in the bridge smart contract, which is monitored by the Consensus Bridge.

The Consensus Bridge uses multiple messaging protocols to transmit the event to Blockchain 2. Once a sufficient number of confirmations are received from messaging protocols, the synthetic token sX is minted in the destination blockchain.

Example: Synth Token Transfer Without Portal

When transferring a synthetic token sX, the bridge uses a Mint-Burn mechanism. The original sX token is sent to the Synthesis smart contract on Blockchain 1, triggering an event in the bridge contract.

The Consensus Bridge sends the message to Blockchain 2 through multiple messaging protocols. Once enough confirmations are gathered, a new instance of the same sX token is minted on Blockchain 2.

Transaction history

Transferring tokens from one blockchain to another using the CrossCurve Token Bridge is a complex cross-chain operation. The user can track its execution in the interface in real time.

Security

Only tokens whose smart contracts have been thoroughly audited by the CrossCurve team are added to the CrossCurve Token Bridge. The audit takes into account many characteristics of the project, and also examines the code of smart contracts for the presence of logic for moving and locking user tokens, which potentially creates a danger to user funds. Only tokens whose code complies with all security rules are allowed to be moved.

Introduction

CrossCurve Pools v2 is an advanced pool system designed to optimize cross-chain liquidity management within the СrossCurve MetaLayer. The system works with three primary asset types: USD-, ETH- and BTC-pegged tokens, which are issued by various projects across different networks. In the hubchain, a set of paired pools is created for each of these asset types. Each pool corresponds to a specific direction (blockchain) and functions as a bridge to that network.

Pool Structure

Each paired pool in the hubchain consists of two tokens:

• Universal token - an asset from Sonic, common across all pools of the same type (xfrxUSD for USD assets, xfrxETH for ETH, and scBTC for BTC).

• Synthetic derivative, backed by the original asset locked in the Consensus Bridge. This can include both single assets and Curve LP tokens.

Cross-Chain Transfer Process

CrossCurve Pools v2 enables asset transfers between blockchains in four stages:

1. Bridge from the source network: The original token is locked in the Consensus Bridge in the source network, and the Consensus Bridge then mints a synthetic token (derivative) in the Sonic network.

2. Exchange for the universal token: The synthetic token is exchanged for the universal token of the hubchain.

3. Exchange for the destination synthetic token: The universal token is exchanged for a synthetic token corresponding to the target blockchain.

4. Bridge to the destination network: The synthetic token is burned in the Consensus Bridge on Sonic, and the Consensus Bridge then unlocks the original token in the destination network.

Advantages Compared to the Previous System

The previous pool system used Curve stable pools with 8 assets, connected via liquidity provider (LP) tokens from one or more pools. CrossCurve MetaLayer introduces a fundamentally new approach — liquidity isolation, where each pool contains liquidity only for a single direction. This design delivers the following benefits:

1. Targeted Incentives

In the previous system, incentives directed into a pool were distributed across all 8 directions, reducing their effectiveness. In paired pools, blockchains can direct incentives exclusively into their own pool, increasing liquidity in that direction and improving bridge conditions for users.

2. Reduced Slippage

In Curve stable pools, increasing the number of tokens in a pool leads to higher slippage under imbalance. A 2-token pool shows significantly less slippage compared to an 8-token one under the same imbalance. Additionally, in the old system, a significant imbalance in one token increased slippage for all 8 directions, while in paired pools, slippage growth is confined to an affected direction only.

3. Improved Liquidity Efficiency

To minimize slippage in the previous system, equal liquidity was required across all 8 directions, which was inefficient for less active ones. Paired pools allow using smaller amounts of liquidity for lower-demand directions while maintaining the same slippage level, thus optimizing liquidity utilization.

4. Lower Risk During Depegs

A depeg – where an asset drops in value relative to its underlying – is a common occurrence. In multi-asset pools within a single network, a depeg can have wide-reaching consequences for all connected networks, leading to a liquidity drain across all tokens in the pool. For example, in the previous system, if one asset dropped to zero in value while each had $100,000 in liquidity, the total loss across the remaining directions could reach up to $700,000.

In CrossCurve MetaLayer’s isolated pools, a depeg from one blockchain affects only a single pool. In the same scenario, losses would be capped at $100,000. The system automatically pauses the affected direction when a depeg is detected (based on price deviation), preventing further risks. However, a pool with the synthetic derivative of the depegged token remains in the hubchain until the price stabilizes.

Introduction

The CrossCurve Oracle Network is a cross-chain messaging service based on BLS signatures. It is a core subsystem of the CrossCurve Token Bridge as well as one of the supported messaging services used within the CrossCurve Token Bridge.

Cross-chain bridges are an attractive target for attackers because the message transmission layer effectively exists outside the onchain execution of both blockchains. In practice, vulnerabilities in traditional bridges are frequent and are almost always related to some form of centralization. A modern alternative is a decentralized cross-chain messaging service that relies on oracle networks secured with BLS cryptography.

Solution architecture

A network of independent oracles is a decentralized set of validators that:

• Monitor events on the source chain (Ethereum, Polygon, Avalanche, and others)

• Reach consensus on observed events

• Collectively sign proofs for the destination chain

BLS (Boneh-Lynn-Shacham) signatures form the cryptographic foundation and allow the system to:

• Aggregate signatures from many nodes into a single compact signature

• Verify the authenticity of a group signature without revealing individual signatures

• Reduce gas costs on destination blockchains thanks to signature compactness

How it works: a three-step process

1. Event listening

Oracles independently monitor smart contracts on the source chain. When a relevant event is detected, such as a cross-chain message being emitted, each node:

• Verifies the correctness of the event

• Generates a cryptographic proof (Merkle proof)

• Signs it with its BLS private key

2. Signature aggregation

The current coordinator collects signatures from network participants:

• Checks that the minimum signing threshold is met

• Aggregates individual BLS signatures into a single multisignature

• Prepares the data package for submission to the destination chain

3. Verification on the destination chain

A smart contract on the destination chain:

• Receives the aggregated BLS signature and event data

• Verifies the signature against the known group public key of the oracle network

• Upon successful verification, delivers the original message to the target address on the destination chain

Advantages of the approach

Security: an attack requires compromising a threshold number of nodes Efficiency: a single multisignature verification instead of N individual checks Decentralization: no single point of failure

MetaLayer API is a unified interface for accessing distributed liquidity across the entire DeFi ecosystem. Unlike standard bridges or aggregators, the MetaLayer acts as an orchestrator by combining liquidity from DEXs aggregators and bridging into a single intelligent routing layer.

For fintech providers, this is the shortest path to integrating crypto functionality without the need to maintain dozens of separate protocols or spend resources on complex backend infrastructure.

Overview

At the core of the MetaLayer is the principle of complexity abstraction. Instead of manually integrating 10 bridges, 20 DEX aggregators or multiple aggregators, you connect to a single API that builds optimal routes on top of existing protocols.

Key benefits for businesses:

• Unique routes: Access to multi-step exchange paths (e.g. swap on Chain A, then bridge, then swap on Chain B) that are not available via direct integrations

• Maximum liquidity: Automatic selection of the best price across all connected liquidity sources

• Flexible monetization: Tools for dynamic fee management and automated revenue distribution

Monetization and partnership

The CrossCurve MetaLayer is designed around a partnership-driven model. Activation of commercial terms consists of two stages:

Agreement on revenue share terms

Before going live, you need to contact our partnership team at a.gluhovskij@eywa.fi or @Eywa_COO. The manager will work out your specific revenue sharing terms with you and activate your API key for withdrawing accumulated fees.

Dynamic partner fees

You have full control over your margin. In each quote request, you can include the partnerFeeBps parameter.

• Flexibility: Set different fees for different asset types or swap directions.

• Calculation: 1 basis point (bps) equals 0.01%. For example, a value of 50 bps corresponds to a 0.5% fee.

• Automation: The system automatically calculates the fee amount and includes it in the final quote for the user.

Quick start

API key and fee address

You can test the API without a dedicated key. In this mode, you cannot set or receive additional fees.

Contact a.gluhovskij@eywa.fi or @Eywa_COO to obtain an API key and register your EVM address. Your fees will be sent to this address.

Action flow for executing a swap

Step 1: Request routes

Your application requests possible transfer routes from network A to network B.

Step 2: Select route and build transaction

API returns options with the estimated time, fees, and output amount. Your application selects the best one.

Then, build the transaction with the selected route.

Step 3: Send transaction

User sends the signed transaction using ethers.js or any Web3 library.

Step 4: Track transaction status

Your application may monitor the transaction status across chains via REST API or WebSocket Monitor.

Step 5: Completion

Transfer completes in the destination network. All confirmation and relay logic is handled by MetaLayer infrastructure.

CrossCurve DAO — is a democratic, transparent, and decentralized organization that makes strategic decisions, engages participants, and incentivizes their contributions.

The goal of CrossCurve DAO is to create long-term incentives for attracting sustainable cross-chain liquidity, as well as to accumulate and manage the protocol’s own liquidity to ensure better conditions for cross-chain swaps in the market.

DAO governance is based on locking the EYWA governance token into veEYWA, which grants voting power. This voting power allows veEYWA holders to participate in decision-making, receive incentives, and earn income from EYWA protocols.

Advantages of veEYWA

Locking EYWA provides you with the following benefits:

• Staking income

• Voting rights and participation in DAO decision-making

• Incentive earnings when voting for pools

• Increased rewards for providing liquidity

• A share of the platform’s fee revenue

Locking EYWA (veEYWA)

veEYWA stands for vote-escrowed EYWA. Users can lock their EYWA tokens for a maximum of 3 years, in exchange for veEYWA. The amount of veEYWA decreases linearly as the chosen lock duration elapses. veEYWA cannot be transferred directly, but can be transferred within an EYWA DAO NFT. The longer you lock, the more veEYWA you receive. For details, please see the lock formula, but the simple explanation is:

• 1 EYWA, locked for 3 years = 1 veEYWA

• 1 EYWA, locked for 2 years = 0.66(6) veEYWA

• 1 EYWA, locked for 1.5 years = 0.5 veEYWA

• 1 EYWA, locked for 1 year = 0.33(3) veEYWA

The longer you lock your EYWA, the greater your voting power (expressed in veEYWA) and the higher the boost you can achieve.

NFT Boosts

Owning an EYWA NFT can affect the amount of veEYWA you receive and, therefore, your voting power. An NFT’s rarity is determined by two parameters - MV (multiplier for veEYWA), a multiplier applied to the veEYWA you receive; as well as CT (Capacity per NFT), the maximum number of EYWA tokens affected by the NFT’s influence. Check the table below for the characteristics of each rarity level:

EYWA NFTs enhance your DAO voting power, increase returns from staking, incentives, and fees, and allow trading of locked tokens. They also attract investors due to their rarity and functionality.

Here are some ways EYWA tokens benefit different types of users:

For veEYWA holders - those who have locked their tokens to gain voting power:

• Boosts voting power when making DAO decisions

• Boosts the voting power that can be exchanged for incentives (to distribute EYWA inflation across CrossCurve pool gauges)

• Boosts staking income for veEYWA holders

• Boosts the voting power used for distributing $EYWA in CrossCurve pools

• Boosts income from distributing the protocol’s fee revenue among veEYWA holders

Staking Income

Staking income is the reward for long-term holding and locking of EYWA tokens. The longer and larger the locked amount, the higher your staking rewards, which are credited at the end of each epoch.

Also, staking yield depends on the total volume of locked EYWA: the more tokens locked, the lower the yield.

You can view the detailed calculations at the following link.

Using EYWA DAO NFT further increases your staking earnings.

Voting Rights and DAO Decision-Making

CrossCurve DAO functions include:

1. Managing protocol contracts: bridges, new networks, contract deployments, fees, and permissions.

2. Managing the DAO treasury: inflation (amount and rate), incentives for community development, expenses to attract customers and partners, emission to bonds, gauges, and grants.

All of these functions are carried out through voting.

CrossCurve DAO voting is divided into three main categories. Core voting affects the calculation of the voting coefficient for distributing staking rewards.

Core voting addresses:

• Changes/additions to DAO, CrossCurve, and EYWA functionality;

• Incentives;

• Inflation and directives;

• Bonds;

• Grants;

• Gauges.

Other voting topics:

• Incentive proposals;

• Incentive directions;

• Gauge listings.

Miscellaneous votings:

Votings not included in the categories above.

Increased Rewards for Providing Liquidity (up to x2.5)

CrossCurve DAO allows certain pools to receive additional rewards from $EYWA token emissions.

When $EYWA emissions are allocated to a pool, the interface displays a range of possible APR that users can earn by staking their LP position.

The final APR boost depends on the user’s voting power (formed by locking veEYWA) and the ratio of your liquidity to the total liquidity, taking into account other participants’ boosts in a specific pool. A maximum boost can increase your yield by up to 2.5 times.

Thus, holding veEYWA allows you to achieve higher returns when providing liquidity. Using EYWA DAO NFT further increases your yield boost in these pools.

Voting for Pools and Receiving Incentives (Bribes)

Locking EYWA tokens provides unique opportunities for additional income through receiving incentives for voting on certain pools. By voting, veEYWA holders determine the distribution of liquidity and rewards among CrossCurve pools. Projects seeking to attract liquidity offer veEYWA holders incentives (various tokens) in exchange for votes in their favor.

Locking EYWA turns voting rights into a source of income: veEYWA holders choose the most profitable offers and receive rewards in tokens, cryptocurrencies, or other forms of income from the projects. The higher your veEYWA balance, the more profit opportunities you have.

Using EYWA DAO NFT further increases your earnings when voting for pools.

Staking is the process of locking coins for a certain period, making them unavailable for trading. This mechanism supports decentralization and provides rewards to participants.

In the CrossCurve protocol, staking involves locking tokens in the DAO locker. Rewards are accrued every epoch and are tied to each user’s EYWA DAO NFT. Accrual occurs at the start of the new epoch for the previous one. In CrossCurve DAO, the epoch length is one week, with the end of the epoch at Wednesday 24:00 UTC and the start of the epoch at Thursday 00:00 UTC.

By using the “Compound” transaction, a user can add the earned rewards to the corresponding EYWA DAO NFT, in order to add them to the principal of your position and earn compound interest.

More details on reward calculations per epoch are provided below.

Distribution of Rewards Among DAO Participants

Each epoch, a fixed number of EYWA tokens (), is allocated for DAO participant rewards. This amount depends only on the total number of locked EYWA tokens in that epoch. All calculations, including the number of locked tokens and the calculated veEYWA, are performed at the end of the epoch. The allocated rewards are then distributed among participants proportionally to their share of veEYWA.

Algorithm for Calculating Rbase at the Start of DAO Operations

1. Calculating the ratio of all locked EYWA tokens in this epoch to the total possible volume of EYWA tokens (1,000,000,000):

1. If is less than 0.14, then is calculated as:

, where

Inflation - the emission amount in the calculation epoch.

1. If is greater than or equal to 0.14, then is calculated as:

, where

Inflation - the emission amount in the calculation epoch.

All numerical coefficients indicated in the formulas are current at the time of DAO launch. They can be changed by DAO participants via voting.

EYWA DAO NFT is an ERC-721 NFT created when EYWA tokens are locked in the Locker.

Key features:

• Attaching assets: Each EYWA DAO NFT can have EYWA tokens, Vesting Safes, and other EYWA NFTs attached to it.

• Obtaining veEYWA: The obtained veEYWA is automatically tired to the corresponding EYWA DAO NFT.

• Multiple ownership: A user can own an unlimited number of EYWA DAO NFT.

• Summation of veEYWA: The total amount of a user’s veEYWA is equal to the sum of the veEYWA of all their EYWA DAO NFTs.

Thus, EYWA DAO NFT serves as a hub for managing your locked assets and voting power in the DAO, providing flexibility and scalability in project governance.

Creating an EYWA DAO NFT

When creating an EYWA DAO NFT in the Locker, you can lock EYWA tokens in various states When transferring to the Locker:

1. EYWA tokens (standard ERC-20)

• Ownership is transferred to the Locker contract.

1. Vesting Safe contracts with direct ownership (held in the user’s wallet)

• Ownership of the Vesting Safe contract is transferred to the Locker.

1. Vesting Safe contracts with ownership via an NFT (Vesting Safe contracts attached to an EYWA NFT)

• The Vesting Safe is detached from an EYWA NFT and transferred to the Locker.

• The EYWA NFT ownership is also transferred to the Locker.

1. ERC-20 EYWA tokens with ownership via an NFT (EYWA tokens attached to an EYWA NFT)

• Tokens are detached from an EYWA NFT and transferred to the Locker.

• Ownership of an EYWA NFT is also transferred to the Locker.

Calculating veEYWA:

The Locker calculates the amount of veEYWA based on the total number of EYWA tokens locked, including both standard ERC-20 tokens and those in the Vesting Safe.

Restrictions when creating an EYWA DAO NFT

• You cannot create an EYWA DAO NFT by adding an empty EYWA NFT to the Locker.

• You can attach no more than 100 Vesting Safes and 100 EYWA NFTs to one EYWA DAO NFT.

Modifying an EYWA DAO NFT

You can modify an EYWA DAO NFT in several ways:

Adding additional EYWA tokens:

• You can lock more EYWA tokens in any of the ways described above at the time of creating an EYWA DAO NFT.

Adding/attaching empty EYWA NFTs:

• You can attach additional empty EYWA NFTs to an existing EYWA DAO NFT.

Removing/detaching EYWA NFTs:

• You can detach an EYWA NFT from an EYWA DAO NFT, returning them to the user’s ownership.

Extending the lock duration of tokens:

• You can extend the lock duration of already locked EYWA tokens to increase voting power.

Types of Liquidity Pools

CrossCurve offers two distinct types of pools, each with unique features and earning opportunities.

Stable Pools

Stable pools are designed for assets whose prices are pegged to each other:

• Examples: Stablecoin pairs, such as USDT/USDC

• Derivative Assets: Pairs like wstETH/rETH are also considered stable since their relative prices do not fluctuate significantly

• Goal: Maintain an exchange rate of 1:1 between assets as accurately as possible

• Features: Minimal slippage and stable exchange prices due to a specialized AMM formula

Volatility Pools

Volatility pools are intended for pairs of assets with fluctuating prices:

• Examples: USDT/EYWA, ETH/BTC and other uncorrelated assets

• Formation: Created by combining heterogeneous assets

• Protection: Utilize Curve's unique mechanism to mitigate impermanent loss

• Features: Higher risk but potentially higher returns

Liquidity Provision Process

Adding Liquidity

CrossCurve offers two modes for adding/removing liquidity:

1. Easy Mode

• Allows adding or removing funds with a single asset

• Simplifies the process for beginners

• Automatically handles all necessary conversions and transactions

2. via Curve (Balanced)

• Designed for adding large sums

• Requires balanced addition of assets to optimize yield

• Minimizes slippage losses

Importance of Pool Balancing

When working with liquidity pools, it's essential to understand the concept of balance:

• An ideally balanced pool has an equal percentage distribution of all assets

• For instance, in a xCRVUSDC pool with six s-tokens, the optimal share for each asset is 16.6% of the total TVL

• Adding an underrepresented asset (share <16.6%) earns an additional bonus

• Adding an overrepresented asset (share >16.6%) results in losses

Ways to Earn When Providing Liquidity

1. Trading fees

The primary income source for liquidity providers is the trading fees from swaps occurring within the pool:

• Fees are automatically distributed among all liquidity providers

• The amount of fees received is proportional to your pool share

2. Farming and Additional Rewards

In addition to trading fees, liquidity providers may receive extra incentives:

• EYWA inflation allocated by CrossCurve DAO voting as an incentive to attract liquidity

• Other tokens added by external projects to attract liquidity

• Increased rewards for veEYWA holders (vote-escrowed EYWA)

• Points for participating in external project programs

3. Access to StakeDAO and Convex Strategies for Enhanced Yields

• Obtaining higher yields by placing funds into CrossCurve pools through strategies within “Curve Wars” protocols, such as Convex or StakeDAO

4. Cross-chain Capabilities

CrossCurve's unique advantage is its ability to manage liquidity across different blockchains:

• Liquidity providers can add and withdraw liquidity from all available networks

• Liquidity providers can swap LP tokens across networks without impermanent loss

• The ability to quickly and cost-effectively move funds in search of higher yields

Yield Optimization

To maximize yields when providing liquidity, it's recommended to:

• Analyze pool conditions before adding liquidity

• Select the optimal mode:

• • Easy Mode for small amounts and beginners

  • Balanced mode for larger sums and experienced users

• Monitor pool balance when adding or removing liquidity to earn bonuses rather than incur penalties due to pool imbalances

• Combine with EYWA locking to obtain additional rewards through yield boosts

• Participate in voting for liquidity distribution between polls and vote for your pool (if beneficial, considering other opportunities for selling votes)

Conclusion

Providing liquidity on CrossCurve is a powerful earning tool in DeFi. The platform combines Curve Finance's proven reliability with CrossCurve's innovative cross-chain technologies, ensuring user security, convenience, and potentially high returns.

It’s crucial to remember that liquidity provision always entails certain risks; thus, it’s advisable to carefully study pool mechanisms and yield optimization strategies before making significant investments.

Voting in CrossCurve is more than just participation in governance; it is an effective tool for generating additional income. Your voting power (veEYWA) becomes a valuable asset capable of producing returns alongside basic staking rewards.

How Voting Generates Income

By locking EYWA tokens, you receive veEYWA—voting power that:

• Grants the right to influence liquidity distribution between pools

• Allows support for projects offering additional rewards

• Creates an additional income stream beyond basic staking

Sources of Income from Voting

1. Direct Incentives from Projects

Different projects compete for your support, offering their tokens as incentives for your votes:

• Additional token payouts occur each epoch

• Opportunity to receive tokens from promising projects. Selling immediately or holding onto them is your choice.

2. Monetizing Voting Power through NFTs

A unique CrossCurve advantage is monetizing your voting power by selling EYWA DAO NFTs:

• Vote Selling: Although the veEYWA tokens themselves cannot be transferred directly, you can sell NFTs containing your voting power on the secondary.

• Pricing: NFT value directly correlates with the amount of veEYWA contained and potential income from voting.

• Liquidity of Locked Assets: Option to sell voting power without waiting for the lock period to end.

Given the limited issuance of veEYWA, their value could increase, enhancing the worth of your voting NFTs and creating a third revenue stream.

Strategies for Maximizing Voting Profits

Monitoring High-Incentive Offers

Track projects offering the largest rewards for voting. Analyze proposals, selecting those providing an optimal balance between:

• Reward size

• Project stability

• Token growth potential

Or delegate this task to professionals via CrossCurve's website interface. (This feature will be available soon)

Combining with NFT Boosters

Strengthen your voting power through EYWA NFTs:

• More veEYWA = more votes = higher rewards

• Legendary or Infinity level NFTs can increase voting returns by up to 2.8x and 3x respectively

Active Management of Voting Assets

Regularly participate in votes to avoid idle veEYWA:

• Unused votes yield no extra profits (delegate or remember to vote yourself)

• Monetize your voting power by selling NFTs when necessary

• Reinvest tokens received from voting into staking to leverage compound interest

Conclusion

Voting in CrossCurve is not merely a bureaucratic function but a tangible opportunity to gain additional income, influence the evolution of DeFi, and actively participate in a growing community.

CrossCurve is moving to Sonic

We have made a strategic decision to migrate CrossCurve's hub chain from Fantom (FTM) to Sonic. This is not just a network change - it’s a transition to a new level of speed, efficiency, and possibilities. Let's explore why Sonic is the optimal choice, what benefits it brings to users, and how this step will shape our future.

Why are we moving to Sonic?

1. Game-changing speed

Sonic dramatically accelerates blockchain operations. The average transaction finalization time is just 720 milliseconds.

For comparison:

• Ethereum — ~12 seconds

• Fantom Opera — ~1-2 seconds

This makes Sonic one of the fastest EVM-compatible blockchains. In DeFi, speed is critical: minimal latency reduces arbitrage risks, improves liquidity conditions, and enhances user experience.

Sonic brings blockchain interactions closer to Web2 performance—transactions process instantly, while fees remain minimal.

2. An economic model that rewards projects

Most blockchains either burn fees or direct them to network funds. Sonic takes a different approach:

• Up to 90% of fees are returned to developers

• Projects generate sustainable revenue without raising fees

• Liquidity is redistributed to benefit everyone: users, developers, and token holders

The more activity in the network, the higher the protocol revenues and user incentives.

3. Simple migration and ecosystem support

Sonic is an evolution of Fantom’s technology but with enhanced features.

What does this mean for projects?

• Easy migration — smart contract code requires minimal changes

• $120M support fund — Fantom has allocated grants to migrate dApps to Sonic

• Major centralized exchanges have integrated automatic FTM → Sonic (S) swaps

We gain all the advantages of the new network without losing functionality or liquidity.

Why is Sonic better than other blockchains?

1. ve(3,3) Flywheel: a powerful tokenomics model

Sonic’s economy is built on the ve(3,3) concept, which incentivizes staking, liquidity, and long-term token holding.

This model has already proven successful in Curve, Solidly and Velodrome, creating a sustainable DeFi cycle.

2. Leading DeFi projects are moving to Sonic

Sonic has already attracted top players, including:

• AAVE — a leading DeFi protocol managing $10B+ in assets

• Curve — the largest stablecoin exchange platform

• Solidly and other major DeFi projects — key players in the industry

This means liquidity and users are already migrating to Sonic, making participation in this ecosystem strategically important.

3. Full Ethereum compatibility

Sonic supports EVM, making it fully compatible with existing Ethereum and Fantom smart contracts.

А Sonic Gateway — a native bridge enabling secure asset transfers between Ethereum and Sonic without reliance on centralized solutions.

Conclusion

CrossCurve’s transition to Sonic is not just an upgrade - it’s a leap forward in technology.

What are the key benefits?

• 720ms transactions — faster than any other EVM blockchain

• Up to 90% of fees returned to developers — projects earn more

• Seamless migration with $120M support — transition risks minimized.

• Top DeFi projects onboarded — Sonic’s ecosystem is growing rapidly

Migrating the hubchain to Sonic is a major system upgrade affecting the protocol’s architecture, mechanics, and economy. The principles of working with liquidity are changing, system resilience is increasing, and new earning opportunities are opening up for CrossCurve users. Below are the key stages of this transition:

1. Deployment of Pools on Sonic✅

Pools based on a new architecture—isolated pair pools—are being launched on Sonic. Previously, large multichain pools were used, combining up to 8 blockchains with synthetic derivatives. Now, each pool includes only the liquidity of one isolated blockchain and the hubchain – in this case, the liquid tokens of the Sonic blockchain.

This approach enhances the system’s overall resilience and reduces imbalance risks. Individually, the pools will be less liquid, but the overall architecture will provide greater flexibility, resilience, and potentially higher returns for liquidity providers.

2. Whitelisting on Curve and Activation of CRV Incentives✅

We are initiating a voting process in the Curve DAO to get whitelisted and connect the pools to protocol reward distribution. This will allow us to activate CRV incentives for our pools and increase yields for our liquidity providers. Since the voting takes about two weeks, we are starting the process in advance to launch reward distribution as quickly as possible after migrating our hubchain.

3. Connecting Sonic Pools to Routing

After deployment and basic setup, the Sonic pools will be connected to our routing system. At this stage, swaps through the new pools in Sonic will become available to CrossCurve users. To ensure a seamless transition, Sonic and Fantom pools will operate in parallel, allowing liquidity to flow between them without interrupting system functionality.

4. Activation of CrossCurve DAO Incentives on New Pools✅

After launching the pools and connecting them to the infrastructure, we will activate incentives from CrossCurve DAO – our first step in attracting liquidity to the new Sonic pools. External projects will be able to offer rewards to CrossCurve DAO participants in exchange for votes on specific liquidity pools, allowing users to start earning right away.

5 Connecting Sonic Gems to Incentives on Fantom Pools✅

As Sapphire-tier winners in the Sonic Boom program, we possess special airdrop points called Gems. These are distributed among applications based on product metrics and activity. We will direct all of them toward incentivizing liquidity in our pools in the form of the cmGEMS1 token, using it as a reward distribution mechanism within the protocol.

WE ARE HERE

6. Disabling Incentives on Fantom Pools

As incentives are activated on Sonic pools, they will simultaneously be disabled on Fantom. However, CRV rewards will continue to be distributed for some time after deactivation due to the mechanics of Curve.

7. Disconnecting Fantom Pools from Routing

After most of the liquidity has been migrated to Sonic, Fantom pools will be disconnected from the routing system. Swaps through them will no longer be possible; the pools will remain accessible for withdrawals only. It is especially important for CrossCurve users to move their assets before this stage to avoid high slippage, as the majority of liquidity will have already been relocated.

8. Connecting Sonic Points and Rings to New Pools

At this stage, the pools will start generating Sonic Points and Rings, allowing liquidity providers to participate in additional reward programs, including all future airdrops. Thanks to the new pool architecture, half of the liquidity will be concentrated in Sonic blockchain assets, enabling our users to earn even more incentives

9. Activation of $EYWA and $CRV Rewards via Votemarket

After completing the Curve vote and configuring campaigns on Votemarket, we will activate the reward distribution in $EYWA and $CRV tokens – thus completing the migration of our hubchain to Sonic and fully launching most of the economic incentives in the new pools.

Routing provides a convenient graphical representation of a cross-chain transaction, showing all the transitions and fees involved step-by-step:

Routing Details Legend

- Adding token to the pool

- Removing token from the pool

- Burning of synthetic token

- Receiving asset from the pool (LP or token obtained in exchange)

- Cross-network transition using lock/receive or burn/unlock mechanics

- Token exchange within the pool

- Unwrap the native token

- Wrap the native token

There are situations where a cross-chain operation may be interrupted:

1. The operation is interrupted based on the Slippage condition. If, during the transaction execution in one of the pools, the slippage exceeds the upper limit set by the user, the transaction will be interrupted, and the intermediate tokens will be credited to the user's address on the network where the interruption occurred.

2. The operation is interrupted because the cross-chain call cannot be executed. If the infrastructure facilitating cross-chain interaction fails to execute the cross-chain call, the operation will be interrupted.

The transaction interruption will be displayed as a message in the Transaction history, where the user will be provided with actions to handle the situation.

If an interruption occurs in one of the pools in the cross-chain transaction chain due to the slippage condition, the tokens that were input into the pool will be credited to the sender's account, and the user will be prompted to continue the operation.

Go to Transaction History and click Details next to the interrupted transaction.

To continue a transaction that failed due to a slippage error, click Continue operation.

After clicking the Continue operation button, the application will switch to the Continue operation mode. The difference between the Continue operation mode and Normal mode is that in the Continue operation mode, the User will be sent native tokens (if the User’s wallet doesn’t have the chain’s native token for completing the transaction) to pay the gas fee for continuing the transaction in the chain where the interruption occurred.

After pressing the button, the user will be taken to the Swap interface with preselected assets:

In the top FROM field, the "intermediate" tokens that were credited to the user's wallet on the network where the operation was interrupted will be selected.

In the bottom TO field, the desired asset that the user initially wanted to receive but the operation was interrupted will be selected.

Sequence of actions in the Continue operation mode window:

• Review transaction details such as Slippage and exchange rate in the dropdown menu.

• Give permission for the application to interact with the asset

• Sign transaction.

Total Slippage is the total effective slippage applied across all networks where a swap occurred during a cross-chain transaction.

It is calculated as the sum of slippage percentages for each individual network involved in the transaction (details here).

The user will have one free attempt to continue the transaction with new fees and Slippage conditions. If for some reason you can not continue the operation, сontact support on Telegram / Discord and our support team will help you.

Example of obtaining the av3CRV LP token from the avDAI/avUSDC/avUSDT CrossCurve pool.

Here is the pool address, and the list of supported tokens.

1. To start, go to the Curve Finance website via the link, or go to the Pools tab and enter the name of the pool you wish to find (avDAI/avUSDC/avUSDT) in the search bar. You need to select the network in which the liquidity pool is located where you want to deposit your tokens (liquidity). For this example, the Avalanche network will be used.

1. On the pool page, connect your wallet to the site by clicking on "Connect Wallet".

3. Choose the installed wallet (or use Wallet Connect) and confirm the connection, making sure you are on the original page https://curve.finance.

4. On the pool page, interaction happens through the application highlighted in the screenshot; look for the Deposit tab.

5. In the Pool Details tab, pay attention to which tokens (DAI.e, USDC.e, and USDT.e stablecoins) are part of the pool.

The avDAI/avUSDC/avUSDT pool consists of three stablecoins; accordingly, the pool will be balanced if the share of each asset in the pool constitutes 100/3 = 33.3% of the total TVL of the pool. (more details here)

6. We will demonstrate a balanced method of adding liquidity to the pool – you can use multiple assets so that your operation brings the pool into a balanced state. This method should be applied to avoid penalties and earn additional profit from Curve in cases where you work with large amounts relative to the total TVL of the pool, or when the pool is close to perfect balance.

For balanced funding, in the Deposit tab, select "Add all coins in a balanced proportion" and the system will automatically distribute them in equal proportion. Indicating the amount, confirm spending (click on Approve Spending). In the Edit tab, you can edit the amount of funds available for spending (by default – unlimited)

7. After successful confirmation, you will see a green button labeled Spending Approved. Then, click on Deposit. After confirming the transaction, you will see a green Deposit Complete button, and the balance of av3CRV LP tokens will be displayed in the Your Details tab.

Attention!

Curve pools are based on a specialized AMM formula for trading stablecoins with minimal slippage and stable prices. Differing from the standard AMM formula x * y = k, Curve applies a modification focusing on assets with similar prices, providing effective pricing and liquidity for closely correlated tokens. Pools are adapted to the market by adjusting the asset weights, allowing them to maintain stable exchange prices even with changing market volatility. Therefore, it is necessary to pay attention to the liquidity balance of each stablecoin in the Pool Details tab. Go to the original liquidity pool on Curve you are working with, and assess its balance. For example, let's consider the xCRVUSDC pool.

The xCRVUSDC pool consists of six s-tokens, so the pool will be balanced if the share of each asset in the pool constitutes 100/6 = 16.6% of the total TVL of the pool.

1. If you add one asset to the pool, the share of which is less than 16.6%, you will receive an additional bonus for balancing the pool.

1. If you add one asset to the pool, the share of which is greater than 16.6%, you will receive a penalty in the form of slippage because this operation worsens the pool balance.

1. If you withdraw one asset from the pool, the share of which is less than 16.6%, you will receive a penalty in the form of slippage because this operation worsens the pool balance.

1. If you withdraw one asset from the pool, the share of which is greater than 16.6%, you will receive a bonus because this operation balances the pool.

1. It should be noted that this example is not a financial strategy, and the imbalanced Easy mode is not always profitable (for example, if the pool is balanced) and also depends on the liquidity volume you are working with: the higher your volume relative to the total TVL of the pool, the more likely it is that the imbalanced method will be disadvantageous and you should use the Balanced mode. To avoid high losses of funds, always consider these factors and the condition of the pool before making a decision about the operation.

Incentives interface provides access to the ve(3,3) mechanism in the CrossCurve DAO for external projects and protocols, as well as for veEYWA holders.

Now, owners of locked EYWA tokens (veEYWA) can receive additional rewards for participating in votes for specific liquidity pools, significantly expanding the earning opportunities within the ecosystem. Meanwhile, external projects can acquire liquidity, gain visibility, and secure their status in the cross-chain space.

To get started in the CrossCurve application, go to the Incentives page in the DAO section. Click “Connect wallet”, select a suitable wallet from the list, and confirm the connection, making sure you are on the official page: https://app.crosscurve.fi/incentives

On the Incentives page, detailed information will be displayed:

• Current voting round ends in - remaining time until the voting period ends in this epoch

• Farm pools - pool name and its statistics:

• Basic Volatile - pool type*

* CrossCurve offers two distinct liquidity pools to users: the Stable Pool and the Volatility Pool.

Volatility Pools consist of liquidity (Curve pools) for asset pairs with volatile prices, typically experiencing divergence. For example, USDT vs. EYWA or ETH vs. BTC.

Volatile pairs are formed by combining uncorrelated assets and utilize Curve's unique impermanent loss compensation mechanism for pools containing volatile assets.

Stable Pools are pools of stable liquidity (Curve pools) between assets whose prices are pegged to each other. For example, USDT vs. USDC.

Another case involves derivative assets, such as wstETH and rETH. Although rETH is considered a volatile asset, the trading pair between wstETH and rETH is classified as a stable pool because the price of wstETH does not significantly fluctuate relative to rETH.

Stable pairs on CrossCurve are designed for correlated assets and aim to maintain a 1:1 transfer ratio between them as closely as possible.

• Votes - number of veEYWA votes cast and the percentage of total votes received by this pool among all pools participating in the vote

• Chain - the network in which the pool operates

• TVL - total value locked in the pool

• Volume (24h) - trading volume in the pool over 24 hours

• APR - yield in the pool

• Total incentives - total rewards allocated for the epoch in USD equivalent

For easier navigation, use the filter icon to search for a specific network or token within a pool.

To propose a reward for all CrossCurve DAO participants in exchange for their votes in the next epoch, select the pool to which you want to allocate rewards. At the beginning of the next epoch, these rewards will be evenly distributed among all those who voted for that pool.

In the modal window that appears, select the token in which you want to add rewards and enter the amount to be allocated.

To proceed with adding the selected rewards to the pool, you must give consent by checking the box, as any transaction is final and cannot be reversed, meaning the allocated tokens cannot be refunded.

After confirming your agreement with the reward allocation terms, click Add Incentive and sign the transactions to approve spending (Approve) and add the rewards (Add Incentive)

By navigating to the Vote page in the DAO section, you can view the amount of allocated rewards for DAO participants in the current and upcoming epochs:

Estimated EYWA emission in the next epoch - average amount of rewards allocated for the next epoch in EYWA tokens

Estimated CRV emission in the next epoch - average amount of rewards allocated for the next epoch in CRV tokens

Estimated incentives available in the current epoch - average amount of rewards allocated for the current epoch in USD equivalent

The reward amounts allocated to voters for each pool are displayed in the Incentives column.

On the Dashboard page in your personal statistics, rewards are calculated in the Incentives section. At the end off the epoch, rewards become available for claiming. To claim your rewards, click Claim and sign the transaction(s) in your wallet.

Staking LP-tokens

1. After successfully connecting your wallet, you will see all available pools for staking LP tokens.

After selecting the desired liquidity pool and clicking “Lock LP and get rewards”, we will see a modal window for staking liquidity to earn EYWA and CRV.

After specifying the LP amount, click Approve EYWAUSDT and confirm spending of LP tokens by singing the transaction in your wallet.

Then click Stake, and sign the transaction in your wallet.

After the transaction is successfully completed, the balance of staked LP tokens will be displayed on the page of the pool where you locked the funds in the Staked section.

Unstaking LP Tokens

Unstake LP tokens by clicking Unstake.

After specifying the LP amount click Unstake and sign the transaction in the wallet.

Receiving rewards

For farming rewards in EYWA and CRV simultaneously, click Claim in all pools

Confirm the transaction in Your wallet.

Also you can go to the Merkl dashboard by clicking the link and claim the rewards manually

After successfully connecting your wallet, go to the Claim section and follow the instructions on the Merkl website.

To get started with the CrossCurve app. navigate to the APR calculator page in the Yield section. Click Connect wallet, select the appropriate wallet from the list, and confirm the connection, ensuring you are on the official page: https://app.crosscurve.fi/farm?&calculator=1.

After successfully connecting to the wallet, select the desired pool from the list.

The application will display information about the selected pool:

Your vAPR - total APR in the pool including the boost

Pool TVL - The total value locked in the pool

Total veEYWA - The total amount of veEYWA

To calculate the required amount of veEYWA tokens for obtaining a boost, enter the desired amount of LP tokens for locking in the selected pool in the Your deposit field and adjust the slider to the desired boost level. The Your vAPR line will calculate the APR obtained with the selected boost.

After entering the amount of LP tokens to be locked and the desired boost, the application will calculate the required amount of veEYWA tokens to achieve the boost and the desired APR

Your vAPR - The projected APR with the selected boost

You have - The veEYWA balance in the connected wallet

Need for boost -The required amount of veEYWA to achieve the selected boost

To obtain the necessary amount of veEYWA tokens, use the Locker by clicking Get veEYWA for BOOST.

There are two approaches available for integrating with the CrossCurve MetaLayer service. Choose the one that best fits your tech stack and transaction control requirements.

Token/Chain Data

Advanced Swap Methods

🔗 Full version of CrossCurve tokenomics is available in this spreadsheet

🎬 Initial circulation supply, FDV and initial market cap

Listing price: $0,07 Fully diluted valuation: $70 000 000 Market cap on TGE: $3 023 740 IMC (without liquidity): $921 539

After listing, the total circulating number of the Eywa tokens will be 43 196 286 (4,32% of the total supply). This figure represents the sum of the tokens unlocked on the community round, market-making tokens, airdrop, treasury and KOL tokens.

TGE mechanics

The TGE stage includes the following steps:

1. The Eywa token smart contract will be deployed in Ethereum chain;

2. The entire EYWA emission (1 billion tokens) will be issued and then transferred to the Arbitrum chain using the CrossCurve Token Bridge.

3. The vesting contracts will be deployed in Arbitrum chain.

4. EYWA is an omnichain token and can be moved to Arbitrum, BSC and Fantom chains.

5. The CrossCurve team will send the Eywa token emission to the vesting contracts in accordance with the project’s tokenomics.

6. Token distribution begins after Listing date in a special section on app.crosscurve.fi which will become available after the TGE. On TGE, users will be able to connect their wallets and access their personal vesting safes, linked to their addresses. During the vesting period, Eywa tokens are unlocked according to the scheme defined in tokenomics, and owners can transfer the unlocked tokens to their wallets.

7. The Listing date will occur no later than 14 days after TGE.

🕐 Eywa token vesting rules

The CrossCurve tokenomics outline various user categories, each with different lockup periods. After the TGE, all users will receive their personalized safes with vested tokens.

A vesting period is a time interval during which tokens are unlocked according to a previously approved schedule. The tokens’ unlock logic is programmed into smart contracts and cannot be changed.

A vesting mechanism aims to mitigate pressure on a token market price, reduce the likelihood of speculation, protect the interests of token holders, and positively influence the long-term project development.

Details on vesting periods and the unlock scheme are available in the CrossCurve tokenomics.

The Eywa vesting tokens feature the following:

1. Limited movement. Allocations above 1.5 million tokens can only transfer their vesting tokens to whitelisted addresses, facilitating an OTC market.

   Allocations of smaller size, including all Airdrops rounds and Community round participants can move their tokens but ONLY by using Eywa NFTs. This feature will be available after the NFT collection migrates to Arbitrum.

   In simple terms, this means that these tokens can be tied to Eywa NFTs and sold on an NFT marketplace at any time before the lock-in period ends.

1. Opportunity to use vesting tokens for staking.

   Eywa vesting token holders can stake their tokens before the end of the vesting period and receive staking/farming rewards.

2. Opportunity to participate in the CrossCurve DAO to receive veEYWA votes.

Note: Any changes in the accruals during validators’ rounds will be updated here.

Voting on Emission and Incentive Parameters

Every three months (every 12 epochs), the project may initiate a vote to change the parameters of token emission distribution from the CrossCurve Treasure.

During this voting, the following parameters are determined:

1. The amount of emission per epoch: the total number of EYWA tokens allocated for the project’s development.

2. The percentage allocated to pool rewards (Pools incentives).

3. The percentage allocated to bond creation (Bonds incentives).

4. The percentage allocated to grants (Grants incentives).

5. The percentage allocated to attract external rewards to project pools (Bribes incentives).

Voting Conditions and Restrictions

Voting frequency: Once a voting is initiated, the next one can only occur after three months.

Parameters for voting: All five parameters must be proposed for the voting:

1. Emission amount per epoch.

2. % for Pool incentives.

3. % for Bond incentives.

4. % for Grant incentives.

5. % for Bribe incentives.

Restrictions:

• The sum of percentages for parameters 2-5 must total exactly 100%.

• The emission per epoch cannot exceed the average emission since the DAO’s launch by more than 25%.

• Reducing emission is not restricted and can be lowered to 0, if DAO participants support it.

Initial DAO Parameters

• Emission per epoch: 1 262 295 EYWA tokens.

• • 38% — Pool incentives.

  • 25% — Bond incentives.

  • 0% — Grant incentives.

  • 37% — Bribe incentives.

Emission Distribution Algorithm per Epoch

1. Determining the total emission volume A certain emission amount E is allocated from the EYWA Treasure (for example, the initial 1 262 295 EYWA tokens or another value approved by the DAO).

2. Calculating staking rewards: The amount of staking rewards S is calculated.

3. Calculating token volumes for incentives After deducting the staking rewards, the remaining amount is distributed as follows:

Voting for Pools

All veEYWA holders can participate in weekly (every epoch) voting to distribute Pool incentives among the pools.

What are Pool incentives?

Pool incentives are EYWA tokens, allocated from the CrossCurve Treasury each epoch to attract liquidity providers to the project. DAO participants vote on how this amount is distributed among the pools.

Benefit for Liquidity Providers

The more votes directed to a pool where a provider’s liquidity is located, the higher their reward in the next epoch.

List of Eligible Pools

Only those pools connected to the CrossCurve project are eligible for Pool incentives distribution:

1. Pools created by the project before the DAO launch.

2. Pools added via a DAO vote.

• Any DAO participant can initiate a vote to add a new pool.

• To include a pool in the list, the proposal must receive more than 50% of the DAO votes.

Voting Procedure

Voting takes place on a separate page in the DAO section. To participate, a user must:

1. Distribute all 100% of their votes among the available pools.

2. Press the "Vote" button to confirm their voting choice.

Before the end of the current epoch, a user can cancel their votes and vote again.

Incentive Distribution Scheme Based on Voting Results

1. Vote Counting Process:

At the start of a new epoch, all veEYWA votes cast for pools in the previous epoch are counted. The percentages allocated by participants are converted into a specific number of EYWA tokens directed to each pool.

1. Formula for Incentive Distribution:

where:

— the number of EYWA tokens allocated to pool X.

— the total EYWA token amount allocated to all pools in the current epoch

— the amount of veEYWA votes cast for pool X.

— the amount of veEYWA votes cast for pool i out of all n pools

Thus, the number of EYWA tokens allocated to a pool depends on the proportion of veEYWA votes that pool received relative to all votes.

Reward Distribution to Liquidity Providers

At this stage, all incentives allocated each epoch to attract liquidity providers to the project’s pools are distributed via Angle Merkl service.

Funds Flow Scheme:

CrossCurve Treasure → Pools incentives → Gauge → Angle Merkl → Liquidity Providers

Liquidity providers can claim their rewards:

• Through the project’s pool interface.

• Through the Angle Merkl service interface.

Boosting Liquidity Provider Income for DAO Participants

If a liquidity provider is also a DAO participant, they receive increased rewards through a boost coefficient B.

Boost Coefficient Formula:

where:

— the user’s boost coefficient (cannot exceed 2.5)

D — the total sum of all deposits in the pool (in USD)

d — the user’s deposit amount in the pool (USD).

V — the total veEYWA of all users.

v — the user’s veEYWA amount.

Calculating the User’s Reward:

A maximum boost of B=2.5 does not mean the reward is simply increased by 2.5 times. The total is divided among all liquidity providers taking into account their individual boost coefficient B.

User Reward Formula:

Where:

— the user’s reward

— the total amount of tokens allocated as liquidity rewards

— the user’s boost coefficient

— the user’s deposit size (USD).

— the boost coefficient of user i.

— the deposit size of user i (USD).

Restrictions:

• Maximum boost coefficient: 2.5.

• Rewards are distributed proportionally, taking into account each user’s deposit and boost coefficient.

This system incentivizes DAO participants to provide liquidity, increasing their returns thanks to holding veEYWA.

Introduction

CrossCurve is launching Sonic with an updated pool architecture built on the principle of isolated connections: each network connects to a universal asset within Sonic.

For example, the sxEthereum pool with the universal token xfrxUSD and the s-token с sUSDC_arb

This not only enhances the system's resilience but also opens direct access to all key drop programs of the Sonic ecosystem.

Currently, Sonic incentives are provided for all paired pools on Sonic and for the 3UNIT0 pool.

Season 1

Sonic Points — Rewards for Users

This is the core drop mechanism from Sonic, focused on end users. Points are awarded for holding whitelisted assets and come in two types: passive (for storing assets in a wallet) and active (for using assets in third-party apps, such as CrossCurve), which earn double the passive rate.

Thus, farming Sonic Points through CrossCurve is twice as profitable!

The following assets offer different boosts:

• scUSD — 6x

• scETH, scBTC — 4x

At the end of the drop, Sonic Points will be converted into NFT-safes, from which $S tokens will gradually unlock. All information is displayed in the dashboard: my.soniclabs.com/points

Sonic Gems (cmGEMS1) — Rewards for Applications

This is a separate program for protocols and the second part of the Sonic drop. During the first season, 1 680 000 Gems will be distributed. 262 500 have already been pre-allocated to the winners of Sonic Boom. CrossCurve, as one of the winners in the Sapphire tier, has already received 8750 Gems. The remaining 1 417 500 Gems will be distributed based on user activity and multipliers. For CrossCurve as a bridge, a 5x multiplier applies.

We’ve decided to tokenize these as cmGEMS1 and allocate 100% of these tokens as rewards to liquidity providers in the project’s pools.

What is required from CrossCurve users? - Provide liquidity to the project’s isolated Sonic pools on Sonic - Rewards will be distributed through Merkl and will account for your veEYWA boost, if you have one. This can boost your yield up to 2.5x. The instructions to this particular step can be found .

But perhaps the main advantage of cmGEMS1, unlike Points, is that they can be directly exchanged for $S.

Rings Points — Points from Token Issuer on Sonic

Rings Protocol is the issuer of the stablecoins scUSD, scETH and scBTC, which are present in the Sonic pools on CrossCurve. The protocol has its own drop program — Rings Points, which are awarded automatically, similar to Sonic’s own.

Like Gems, Rings Points can be directly exchanged for $S at the end of the season.

Season 2

Sonic Points — Rewards for Users

This is the core drop mechanism from Sonic, focused on end users. Points are awarded for locking whitelisted assets in CrossCurve pools.

The following assets offer different boosts:

• scUSD — 6x

• scETH, scBTC — 4x

All information is displayed in the dashboard: my.soniclabs.com/points

Conclusion

CrossCurve’s transition to Sonic is not just an upgrade, but a real expansion of economic opportunities for our liquidity providers. With the new pool architecture, almost every provider can receive triple incentive accrual - not counting CrossCurve’s own rewards.

As part of Sonic’s Airdrop Season 2, CrossCurve has launched the CrossCurve MetaPoints program to reward active users of CrossCurve.

Rules

Participants:

• Users who provide liquidity to participating pools* in the Farms tab by staking LP tokens in the CrossCurve app

• Users swapping cross-chain via the Trade interface (as long the the swap’s route passes through the Hubchain)

Rewards:

Participants receive MetaPoints. Also, their activity helps CrossCurve receive more Sonic Gems, which will be swapped to $S tokens at the end of Sonic’s airdrop season 2. All of the received $S tokens will be distributed among all the participants who got enough MetaPoints to receive at least one $S

Pool marking:

Pools participating* in the MetaPoints program will be marked with a special symbol .

Point accrual mechanics for liquidity providers

• Only the specially marked pools in Farms are included

• Points accrue only for the volume of s-tokens in the LP:

○ E.g., if the LP token only has 40% of its TVL is in s-tokens, then only this 40% counts towards accrual, not the other 60%.

• Accrual formula:

○ 1 point = 1$ s-token left in the pool for 1 day

• Accrual frequency:

○ daily at 00:00 UTC

• Each pool could have an individual multiplier that increases or decreases the total amount of accrued points.

Accrual mechanics for users moving liquidity

• Only cross-chain swaps receive points (as long as the route passes through the Hubchain).

• Swaps below $10 do not count.

• Users get 100 MetaPoints for every $10 swapped

Integration

• Users can find MetaPoint accrual information on the Leaderboard page in each relevant tab:

- My MetaPoints — total MetaPoints earned by the connected wallet

- In Farms — total MetaPoints earned by staking in Farms

- In Swaps — total MetaPoints earned for cross-chain swaps in Trade

- Total MetaPoints — total amount of MetaPoints earned by all the participants of the CrossCurve MetaPoints program

• In the “Frams” LP staking interface, participating pools will have the icon next to them, alongside the point multiplier.

• In the “Trade” interface, the expected point value of the swap will be reflected alongside points from Season 2 of Sonic’s airdrop.

FAQ

1. How do I earn $S tokens Swap on CrossCurve or provide liquidity to CrossCurve pools

2. Which pools are participating in this program? Only the selected pools marked by the program’s icon in the interface

3. Does my entire staking position accrue points? No, only the part reflecting the % of s-tokens in the pool

4. How is the value of the LP token determined? In USD based on the average daily value

5. How frequently do the LP points accrue? Daily

6. What can I do with MetaPoints? At the end of the Sonic’s Airdrop Season 2, they will be converted into $S tokens

Slippage is the price change caused by external market movements and not related to the user's operation within the pool. Slippage strongly depends on the liquidity volume inside the pool. If a token pool has low liquidity, significant changes in the exchange rate within the pool require less market movement.

In the settings, you can specify slippage (by default, the parameter is set at 0.5%) Slippage is a change in price caused by external market movements and not related to the user's activity in the pool. Slippage highly depends on the liquidity volume inside the pool. If a token pool has low liquidity, significant rate changes within the pool require less market movement.

CrossCurve users can configure the maximum permissible slippage for cross-chain operation:

You can always see the exact total value in Routing details → Total slippage.

When you set a slippage tolerance in the app, this value is treated as the maximum slippage for the entire route.

Allocation rules:

● Stable pools always receive max / 10.

○ Example: if max = 1%, each first stable pool in a chain gets 0.1%.

○ Only the first stable pool in each chain applies slippage.

● Crypto pools receive the remaining slippage.

○ The remainder is evenly distributed across all chains that contain crypto pools.

○ Only the first crypto pool in each chain applies slippage.

● Other swaps in the same chain receive 0%.

● Therefore, total slippage ≤ your chosen max.

Total Slippage is the total effective slippage applied across all networks where a swap occurs during a cross-chain transaction.

It is calculated as the sum of slippage percentages for each individual network involved in the transaction.

Slippage Allocation Examples (Max = 1%)

You can find the rules for distributing slippage in the table below:

If you set the value too low, you will receive a warning and your transaction may fail due to low slippage:

If you have set a value that is too high (e.g. 1%), which significantly exceeds the recommended value of 0.5%, the transaction may be executed at an unfavorable rate due to frontrun:

To provide liquidity to Sonic pools:

• Select the pool where you want to transfer liquidity, e.g., xsArbitrum.

• Determine the required token amounts.

Withdrawing Liquidity

Example of using Easy mode for withdrawing liquidity of the EUSD LP token into the USDT stablecoin

To start working in the CrossCurve application, go to the Liquidity section. After successfully connecting your wallet, in the Choose pool window, select the EUSD pool. This mode allows you to exchange the liquidity token into a single stablecoin without interacting with the liquidity pool interface on Curve.

1. Having selected the Withdraw operation and Easy mode, proceed to the exchange modal window by pressing Next.

1. Next, select the USDT stablecoin (or any other available asset participating in the EUSD pool) to withdraw liquidity and choose the preferred network of the received original asset.

1. After entering the amount of tokens to be withdrawn, the system will calculate the number of LP tokens received and the gas fee. By pressing Routing details, the Routing will be displayed.

1. The first transaction requires allowing the spending of EUSD by pressing “Approve EUSD” and signing the transaction in the wallet. For signing the transaction, you must hold the native token of the network in which the transaction is being conducted to pay for the gas.

After confirming the spending of EUSD, a “Swap” button will appear.

1. By pressing the "Swap" button, a request will be sent to the wallet to confirm the transaction of exchanging the EUSD LP token from the EUSD pool to the USDT stablecoin on the Arbitrum network.

6. After signing the transaction, a notification about the transaction sending, the ongoing exchange, and the estimated waiting time will be received. The status and progress will be displayed in the top right corner.

Withdrawing Liquidity

Step 1. Go to xCRVUSDC pool on Curve and analyze the optimal way to withdraw funds from the pool:

A balanced method of withdrawing liquidity from the pool is recommended – you will receive s-tokens in proportion from several assets so that your operation brings the pool into a balanced state.

Step 2. After connecting the wallet, go to the Withdraw/Claim tab and use the Balanced mode. After entering the amount to be withdrawn, the AMM will distribute the s-tokens in proportion to the pool's balance from the total TVL.

This method should be applied to avoid penalties and earn additional profit on Curve in cases when you are working with large sums relative to the total TVL of the pool, or when the pool is close to perfect balance. After pressing Withdraw, confirm the operation in the wallet. After completing the operation, the system will issue a Withdraw Complete message.

Step 3. Convert the required s-tokens in the CrossCurve interface.

1. In the Input window, select the s-token for conversion and specify the amount of s-tokens to be converted.

2. In the Output window, select the token for conversion, approve the spending of the s-token by clicking Approve scrvUSDC_o, and confirm the transaction in the wallet.

1. After approving the spending of scrvUSDC_o, a Swap button will appear.

4. By pressing the "Swap" button, a request will be sent to the wallet to confirm the transaction of exchanging the scrvUSDC_o s-token for the selected crvUSDC LP.

5. After signing the transaction, a notification about the transaction sending, the ongoing exchange, and the estimated waiting time will be received. The status and progress will be displayed in the top right corner.

Voting for pools and earning incentives

Locking EYWA tokens provides unique opportunities to earn additional income by receiving incentives for voting on specific pools. veEYWA holders use their votes to direct liquidity distribution and rewards across CrossCurve pools. Projects seeking liquidity offer incentives (various tokens) to veEYWA holders in exchange for their votes.

Locking EYWA tokens transforms voting rights into income streams: veEYWA holders select the most beneficial proposals and receive rewards in tokens, cryptocurrencies, or other forms of income from participating projects. The higher your veEYWA balance, the greater your potential rewards.

Using EYWA DAO NFTs further enhances your earnings when voting on pools.

To start using the CrossCurve application, navigate to the Vote page under the DAO section. Click «Connect wallet», select your wallet from the list, and confirm the connection, ensuring you are on the official page: https://app.crosscurve.fi/vote-pools

After successfully connecting your wallet, open the Pools tab to participate in pool voting.

You will see the following details:

• Current voting round ends in - Countdown timer indicating when the current voting round concludes

• Total voting power available for this epoch - Combined voting power of all DAO participants for the current epoch

• You have - Number of your locks and their voting power in veEYWA tokens

• Voted - Number of your locks and the total veEYWA voting power you have already allocated this epoch

• Ready for voting - Number of locks available for voting and their total veEYWA voting power

• Estimated EYWA emission in the next epoch - Estimated EYWA token rewards allocated for the upcoming epoch

• Select % vote - Select the percentage of your voting power allocated to the chosen pool

• Votes sent - Percentage of voting power you have already allocated to each pool

• Est. rewards - Estimated reward amount in USD equivalent

CrossCurve offers two distinct liquidity pools to users: the Stable Pool and the Volatility Pool:

* Volatility Pools consist of liquidity (Curve pools) for asset pairs with volatile prices, typically experiencing divergence. For example, USDT vs. EYWA or ETH vs. BTC. Volatile pairs are formed by combining uncorrelated assets and utilize Curve's unique impermanent loss compensation mechanism for pools containing volatile assets. ** Stable Pools are pools of stable liquidity (Curve pools) between assets whose prices are pegged to each other. For example, USDT vs. USDC.

Another case involves derivative assets, such as wstETH and rETH. Although rETH is considered a volatile asset, the trading pair between wstETH and rETH is classified as a stable pool because the price of wstETH does not significantly fluctuate relative to rETH.

Stable pairs on CrossCurve are designed for correlated assets and aim to maintain a 1:1 transfer ratio between them as closely as possible.

To participate in voting, select the pool you're interested in, adjust the percentage of your voting power to allocate, and click Vote. Then, sign the transaction in your wallet.

You can view detailed information about your submitted votes by expanding the Votes sent menu.

To cancel your current vote for a specific pool, click Reset. To remove all your votes across all pools, click Reset all.

When confirming vote cancellation, all your votes for the selected pool will be withdrawn. To proceed, click Ok and sign the transaction in your wallet.

Proposals provides the CrossCurve DAO community with tools to manage and guide the protocol's development:

- A platform for managing and voting on proposals impacting the CrossCurve protocol

- Decentralized decision-making by token holders

DAO members actively participate in shaping the CrossCurve protocol by:

• Creating proposals: members can introduce initiatives such as protocol parameter adjustments or fund allocation.

• Voting: users vote For/Against proposals using their veEYWA tokens (vote weight corresponds to veEYWA balance).

• Status tracking: displays proposals categorized by active, completed, and pending, along with their outcomes.

To begin interacting with proposals in the CrossCurve app, visit the Proposals page at under DAO → Vote, then click Connect wallet.

The Proposals page lists DAO proposals, each showing:
