Cross-Chain Swaps Liquidity

Provision of liquidity for cross-chain pools at Curve

deBridge is a decentralized infrastructure that is fully composable with the existing DeFi ecosystem. That’s why we don’t need to invent our own AMM or DEX, but just create liquidity pools for deAssets in existing DEXs. In every blockchain supported by deBridge, there will be a liquidity pool for deUSDC at Curve or protocols that support the concept of the stable swap.
Cross-chain swaps are one of the applications built on top of deBridge infrastructure that enables users to perform swaps from any asset on one chain to any asset on another.
Here are the instructions on how to deposit liquidity into the pool for each blockchain/L2.

Arbitrum deUSDC/2CRV pool

This is a stablecoin pool at Curve that contains deUSDC (USDC bridged through deBridge) paired with 2CRV - Curve token that represents the basket of two stable coins (USDT+USDC)
In case you want to deposit $X amount of liquidity into this pool, please bridge half ($X/2) amount of USDC from Ethereum to deUSDC in Arbitrum through dePort. The other half should be bridged through Arbitrum’s default bridge https://bridge.arbitrum.io/ in the form of USDT or USDC.
Be aware that you will need to have some ETH on your wallet in Arbitrum in order to cover gas costs to broadcast the transaction.
Once you have deUSDC and USDC/USDT in your wallet balance on Arbitrum (you can check through https://arbiscan.io/), you can deposit the liquidity at Curve.
