Hubchain Pools and Assets

CrossCurve pools and assets are integrated within the Fantom ecosystem.

CrossCurve facilitates the swapping of s-tokens within Curve pools on the Fantom Hubchain. All liquidity in CrossCurve on Hubchain is composed of s-tokens. These s-tokens are collateralized synthetic assets issued by the CrossCurve Consensus Bridge. Each s-token is fully backed by the original asset to which it is pegged, with these assets securely locked in the CrossCurve Token Bridge on the source blockchain. Audited by SmartState.

Specialized tokenized assets that facilitate cross-chain trading and yield generation. These s-tokens, typically part of CrossCurve's core stable pools, enable the exchange of similar tokens, thereby creating a unified cross-chain liquidity market. By aggregating liquidity across various blockchains, s-tokens play a pivotal role in streamlining cross-chain operations and enhancing the efficiency of decentralized trading within the Curve-based protocol.

To understand the naming convention of s-tokens on CrossCurve, particularly when incorporating a list of supported networks within the name, such as "scrvUSDT_e," let's break it down:

• The prefix "s" typically stands for "synthetic", indicating the type of token.

• The main body of the name, such as "crvUSDT," specifies the underlying asset. Here, "crvUSDT" indicates that the token is related to CrossCurve pools, and "crvUSDT" is the ticker of the actual pool, xCRVUSDT, being used.

• The suffix after an underscore, such as "e," represents the network on which the token operates. For instance, "e" might denote the Ethereum network.

In this naming structure, "scrvUSDT_e" would represent a synthetic version of the CrossCurve s-token operating on the Ethereum network, to work with the liquidity in the xCRVUSDT pool.

Each different suffix corresponds to other supported networks, providing a quick reference to the cross-chain capabilities of the s-token within the CrossCurve platform:

e - Ethereum network

ar - Arbitrum network

o - Optimism network

av - Avalanche network

p - Polygon network

b - Binance Smart Chain network

ba - Base network

g - Gnosis network

m - Mantle network

me - Metis network

mo - Mode network

bl - Blast network

l - Linea network

t- Taiko network

c - Celo network

f - Fraxtal network

t_t - Kava nework

s - Sonic network

ft - Fantom network

Each different body of the name, such as "crvUSDT," specifies the supported pool:

crvUSDT - xCRVUSDT pool

crvUSDC - xCRVUSDC pool

3CRV - xCRVUSDT, xCRVUSDC, xSTABLE pools

3crypto - x3CRYPTO pool

2CRV, 3Pool, 4Pool - xSTABLE pool

USDC, USDT, USDB, USDCe, 3pool, FrUsdt, USDt - xSTABLE2, xSTABLE3 pools

WETH - xWETH, xWETH2 pools

ETH, wfrxETH - xWETH2 pool

2BTC, BTC.b, WBTC, BTCB, cbBTC - xBTC pool

CRV, CRVTRI - xCRV pool

CrossCurve supports the use of both standard assets and LP tokens as collateral for s-tokens. Below, you will find a list of cross-chain pools, the s-tokens they contain, and the assets backing them.

LP tokens in the CrossCurve ecosystem offer liquidity providers a means to engage with various DeFi platforms across multiple blockchains simultaneously. By providing liquidity, participants receive LP tokens, which represent a claim on their share of the pool's assets and its yield. Holding LP tokens allows providers not only to decide when to withdraw their assets but also to benefit from enhanced returns through cumulative rewards from both Curve and the CrossCurve DAO. Essentially, LP tokens signify ownership of a portion of the liquidity pool, enabling providers to earn returns on their stakes and facilitating cross-chain transactions within the Curve finance ecosystem.

xsStable pools

Synthetic tokens are categorized into three types:

• s_Stable_chain, where Stable represents a USD asset variant, and chain is the network where the asset is used.

Each type of synthetic token corresponds to a pool where it can be paired in an LP token:

• xs_chain, where xs is a stable pool, and chain is the network where the asset is used.
