# Integrate YBridgeVault Contract ## YBridgeVaultV3 ## State-Changing Functions ### deposit ```solidity function deposit(uint256 vaultTokenAmount) ``` Initiate a deposit request. The `vaultTokenAmount` is the desired pool token to be deposited. After deposit, the liquidity provider will receive `XYWrappedToken` (`xyUSDT`, `xyUSDC` or `xyETH)`, along with another transaction sent by YBridge worker. ### withdraw ```solidity function withdraw(uint256 shareAmount) ``` Initiate a withdrawal request. The `shareAmount` is the desired amount of `XYWrappedToken` to be redeemed to the underlying token. Similar to `deposit`, you will receive the underlying vault token along with another transaction sent by YBridge worker. ## Public States #### acceptDepositRequest ```solidity bool public acceptDepositRequest; ``` We can tell whether a YBridgeVault accepts deposit request or not from this state. #### acceptWithdrawRequest ```solidity bool public acceptWithdrawRequest; ``` We can tell whether a YBridgeVault accepts withdraw request or not from this state. #### isDepositCompleted ```solidity mapping (uint256 => bool) public isDepositCompleted; ``` We can tell whether a deposit request is completed by giving the deposit request ID from this mapping. #### isWithdrawCompleted ```solidity mapping (uint256 => bool) public isWithdrawCompleted; ``` We can tell whether a withdrawal request is completed by giving the withdrawal request ID from this mapping. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
