SyncSwap USDC-USDT pool

The “USDC—USDT” strategy allows users to deposit their assets in four ways in a zkSync vault using either: I) LP token; II) USDC and USDT separately; III) ERC20 token (that is in our whitelist); IV) solo native token (ETH). The token ratio in the pool is unstable. In case an ETH token is deposited, it is split into two even parts. One half is swapped for USDC and another half is swapped for USDT. In case an ERC20 token is deposited it is swapped for WETH first and the app unwraps it to make ETH, after that the strategy performs the same actions as if it was ETH deposited initially. Having USDC and USDT as the required assets, the vault provides these funds as liquidity to SyncSwap and obtains USDC/USDT LP tokens in return. No staking is to be done in the scope of this strategy, hence rewards consist of swap fees only. Rewards are obtained in ETH and are immediately added to a user’s deposit. Thus, to perform a compound, the strategy relies on a difference between the amount of a deposit at a given moment and its amount at a moment of a previous compound (or initial amount if no compounds have been made).

When a user decides to withdraw then the following options are available for them: I) LP token; II) ETH and USDT separately, III) solo ETH, and IV) whitelisted ERC20. Users should pay the Parallax fee on their earnings upon withdrawal.
