Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ownership is not renounced (belongs to a wallet)

AnyswapV5ERC20.depositWithTransferPermit(address,uint256,uint256,uint8,bytes32,bytes32,address) (#339-342) ignores return value by IERC20(underlying).transferWithPermit(target,address(this),value,deadline,v,r,s) (#340)
Ensure that all the return values of the function calls are used.

Pragma version0.8.2 (#23) allows old versions
solc-0.8.2 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in SafeERC20.callOptionalReturn(IERC20,bytes) (#121-132):
- (success,returndata) = address(token).call(data) (#125)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
