ICE Token

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

IceToken._init (#135) is written in both
_init = true (#291)
_init = false (#305)
Fix or remove the writes.

Contract ownership is not renounced (belongs to a wallet)

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

IceToken.depositWithTransferPermit(address,uint256,uint256,uint8,bytes32,bytes32,address) (#332-335) ignores return value by IERC20(underlying).transferWithPermit(target,address(this),value,deadline,v,r,s) (#333)
Ensure that all the return values of the function calls are used.

solc-0.8.3 is not recommended for deployment
Pragma version^0.8.0 (#3) allows old versions
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) (#101-112):
- (success,returndata) = address(token).call(data) (#105)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
