SyncSwap USDT-ETH pool

The “USDT-ETH” strategy allows users to deposit their assets in four ways in an zkSync vault using either: I) LP token; II) ETH and USDT separately; III) ERC20 token (that is in our whitelist); IV) solo native token (ETH). Token ratio in the pool is 50:50. In case an ETH token is deposited, it is split into two even parts. One half is used swapped for USDT while the other half remains as is. 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 ETH and USDT as the required asset, the vault provides these funds as liquidity to the SyncSwap and obtains ETH/USDT LP token in return. No staking to be done in 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 an 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, IV) whitelisted ERC20. Users should pay the Parallax fee on their earnings upon withdrawal.
