SHARPEI [Shar Pei] Token

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

TokenRecover.recoverERC20(address,uint256) (#1128-1130) ignores return value by IERC20(tokenAddress).transfer(owner(),tokenAmount) (#1129)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
