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.

CrossCurve MetaLayer is a unified decentralized infrastructure for cross-chain liquidity and incentives, powered by the Curve AMM. It enables efficient swaps, yield generation, and access to deep DeFi liquidity secured by the Consensus Bridge.

MetaLayer Architecture

CrossCurve MetaLayer emerged as a logical extension of the decentralized EYWA bridge. A simple “bridge” is no longer sufficient—more advanced solutions are required for real

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.

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

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.

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

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, 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.

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

🔗 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 will be deployed in chain;

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

3. The vesting contracts will be deployed in chain.

4. EYWA is an omnichain token and can be moved to ,

🕐 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 .

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 . This feature will be available after the migrates to Arbitrum.

   In simple terms, this means that these tokens can be tied to Eywa NFTs and sold on an 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 .

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

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.

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

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.

Liquidity Section and its Functionality

To start working in the CrossCurve application, go to the Liquidity section, in the top right corner click “Connect wallet”, select a suitable wallet from the list and confirm the connection, making sure that you are on the original page https://app.crosscurve.fi/liquidity.

1. After successfully connecting, in the Choose pool window, select the pool or asset you are interested in for working with liquidity.

Once you have chosen the necessary asset, the interface will display the TVL in the selected pool, as well as a link to the original pool of the selected asset on , your Wallet Balance showing the amount of the asset, and the Estimated APR for Farming in the selected pool.

1. The next step is to select the operation to be performed with the asset ( or ) and the method of execution, or .

For convenience, a quick link to add the token to the wallet via the contract address has been added for correct balance display. By clicking on the “+”, a request will pop up to add a custom token. After signing, it will be displayed in the wallet.

The EYWA NFT collection can be found on the Aurora and Arbitrum blockchains.

You can view your EYWA NFTs right on our website in the NFT->Gallery tab.

The Gallery/Bridge tab allows you to see all the connected wallet’s NFTs on the Aurora chain available for bridging to the Arbitrum chain.

The Gallery/Merge tab allows you to see all of the connected wallet’s NFTs on the Arbitrum chain available for rarity increase via merging.

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

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

Here is the pool , and the of supported tokens.

1. To start, go to the Curve Finance website via the, 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.

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.

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.

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.

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.

After successfully connecting your wallet in the «Gallery/Merge» tab, the gallery will show all the NFTs stored in the connected wallet, sorted by .

For your convenience, use the NFT rarity filter to choose the rarity category you want to level up.

Select the necessary number of NFTs for merging and rarity increase and click «Merge»:

Liquidity provision on CrossCurve offers the chance to contribute to the market stability of cross-chain assets. By staking tokens in liquidity pools like EYWAUSDT or CrossCurve frxUSD, providers earn trading fees from swaps occurring within the pool. This process not only provides a potential income stream through fees and rewards but also plays a crucial role in facilitating smooth cross-chain transactions.

Savvy investors can leverage CrossCurve's advanced AMM algorithms to balance risk and return, optimizing their positions in a multi-token ecosystem. Always consider the associated risks and conduct due diligence before participating.

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.

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.

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 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 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.

Staking is the simplest way to earn passive income in CrossCurve. All you need to do is lock EYWA tokens (instructions available here), which automatically makes you a member of our DAO and enables you to receive rewards every epoch. You can boost your earnings through additional mechanics like longer lock durations, using NFTs, and participating in votes.

How does staking work in CrossCurve?

Each epoch, a portion of EYWA tokens from the DAO Treasury is allocated to incentivize protocol activity. Most of these tokens go to rewarding DAO participants.

To receive these rewards, you must lock EYWA tokens in the DAO Locker. Once locked, you receive an NFT that records your voting power — veEYWA. The more veEYWA you hold, the larger your share of the rewards.

Each epoch runs from Thursday 00:00 UTC to Wednesday 24:00 UTC. At the start of each new epoch, rewards from the previous one are .

How to maximize your APR?

Formulas:

• veEYWA = ((EYWA amount × lock period in weeks) ÷ 156

• User share = your veEYWA ÷ total veEYWA in DAO

• Reward = User share × total reward pool (EYWA)

• Weekly Return Rate (WRR) = Reward ÷ locked EYWA amount

For example, if you lock 156 EYWA for 1 week, then you will get:

• 1 veEYWA

If total veEYWA in the DAO is 1 000, and the reward pool is 1 000 EYWA, then your reward is:

• 0.1% of the pool = 1 EYWA

Weekly return rate (WRR): 0.64%

Your income depends directly on your share of veEYWA. To increase it, you can:

1. Lock more EYWA tokens

2. Extend your lock duration

3. Use EYWA NFT with a

These methods can be combined. Here are strategy examples:

1. Increasing EYWA amount

Locking 1560 EYWA for 1 week will get you:

• 10 veEYWA (10 times more)

If total veEYWA in DAO is 1009, then your share is:

• 0.99% of the pool = 9.9 EYWA (9.9 times more)

• Weekly return rate (WRR): 0.63% (almost no change)

2. Increasing lock duration

Locking 156 EYWA for 3 years (156 weeks) will get you:

• 156 veEYWA (156 times more than when locking for 1 week)

If total veEYWA in DAO is 1 155, and the reward pool equals to 1 000 EYWA, then your share is:

• 13.5% of the pool = 135 EYWA (135 times more)

• Weekly return rate (WRR): 86.5% (135 times higher)

3. Using NFT with x3 multiplier

Locking 156 EYWA for 1 week and using NFT with the x3 multiplier will get you:

• 3 veEYWA (3 times more than without an NFT)

If total veEYWA in DAO is 1002, and the reward pool equals to 1 000 EYWA, then your share is:

• 0.29% of the pool = 2.9 EYWA (2.9 times more)

• Weekly return rate (WRR): 1.9% (approximately 3 times higher)

4. Combined strategy: increasing lock duration + utilizing NFTs

Locking 156 EYWA for 156 weeks and applying NFT x3 will get you:

• 468 veEYWA (468 times more)

If total veEYWA in DAO is 1467, and the reward pool equals to 1 000 EYWA, then your share is:

• 31.9% of the pool = 319 EYWA (319 times more)

Weekly return rate (WRR): 204.5% (319 times higher)

How other participants affect your APR

In addition to the steps you can take to maximize your APR, it’s important to consider “external” conditions. In the section “How to increase staking income,” we looked at examples where the veEYWA volume of other DAO participants was static. But in reality, this figure is constantly changing. One important point: how other participants lock their EYWA also affects your final yield.

Reward distribution specifics depending on veEYWA amounts

Let’s consider a few simple scenarios with two DAO participants. Suppose that in the previous epoch, only two users participated in the DAO:

Scenario 1: both locked 75 000 EYWA for the maximum term (3 years)

• veEYWA of participant A = 75 000

• veEYWA of participant B = 75 000

• Total veEYWA = 150 000

• Shares are equal — both participants receive 50% of the rewards

Scenario 2: both have 75 000 EYWA, but:

• Participant A locks for 3 years → 75 000 veEYWA

• Participant B locks for 1 year → 25 000 veEYWA

• Total veEYWA = 100 000

• Participant A receives 75% of all rewards

Based on the the total reward pool for the week (epoch) is 13 190.73 EYWA, therefore:

• Reward A: (75 000 / 100 000) × 13 190.73 = 9 892.5 EYWA

• Reward B: (25 000 / 100 000) × 13 190.73 = 3 297.5 EYWA

Weekly Return Rate (WRR):

• WRR A = (9 892.5 ÷ 75 000) × 100% = 13.19%

• WRR B = (3 297.5 ÷ 75 000) × 100% = 4.37%

APY calculation:

• APY A = ((1 + 13.19% ÷ 100%)^52 – 1) × 100% ≈ 62 700%

• APY B = ((1 + 4.37% ÷ 100%)^52 – 1) × 100% ≈ 824%

“Compound” button and APY

To receive staking rewards each epoch, you must press the “Compound” button. This action adds the accrued reward to the lock amount.

Increasing the lock amount raises your veEYWA share and, accordingly, your reward in the next epoch. The yield displayed on the locker page (APY) is shown assuming regular use of Compound — based on the principle of bank compound interest.

If you do not press Compound, your yield will be lower than what is shown in the interface. Therefore, to earn income that matches the displayed APY, you must manually add the reward to the lock each epoch.

How to maximize earnings

1. Lock EYWA for the maximum term

2. Use NFTs with a high multiplier

3. Press “Compound” each epoch

4. Participate in incentive voting

Conclusion

Staking in CrossCurve is more than just passive income. It includes many mechanics that allow you to earn returns far beyond traditional staking.

You’re not just earning — you’re helping shape the CrossCurve ecosystem and receiving real rewards for it.

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 )

Rewards:

Participants receive MetaPoints. Also, their activity helps CrossCurve receive more , which will be swapped to $S tokens at the end of . 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 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 ).

• Swaps below $10 do not count.

• Users get 100 MetaPoints for every $10 swapped

Integration

• Users can find MetaPoint accrual information on the Leaderboard 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 .

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 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 , 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:

This mode allows you to exchange a single stablecoin into the liquidity token without interacting with the liquidity pool interface on Curve.

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.

To begin using the CrossCurve application, go to the Early Farming Program page in the Vesting section. Click «Connect wallet», select the appropriate wallet from the list, and confirm the connection, making sure you are on the official page:

After successfully connecting your wallet, to display the rEYWA balance in your wallet, you must switch the network to Fantom by clicking Switch chain and confirming the network change in your wallet.

Once connected to the Fantom network, the application will display the rEYWA token balance in your wallet. To exchange rEYWA for the Vesting safe with EYWA, you need to move your rEYWA tokens to the Arbitrum network by clicking Bridge rEYWA to Arbitrum and singing the transaction in your wallet.

Overview

CrossCurve SuperDVN is a verification module (DVN, Decentralized Verification Network) compatible with the LayerZero . It leverages the CrossCurve Consensus Bridge as its internal mechanism for cross-chain message verification and transmission.

SuperDVN serves as a sovereign data verification layer for cross-chain applications, providing a decentralized, secure, and resilient environment for communication between blockchains.

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 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.

Withdrawing Liquidity

Step 1. Go to 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.
