STAX [StableX] Token

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

StaxToken._writeCheckpoint(address,uint32,uint256,uint256) (#987-1005) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#997)
Don't use strict equality to determine if an account has enough Ether or tokens.

StaxToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#853-894) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,SUSHI::delegateBySig: signature expired) (#892)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#316-322):
- (success) = recipient.call{value: amount}() (#320)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#382-403):
- (success,returndata) = target.call{value: weiValue}(data) (#386)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
