report
Token is either risky or in presale. For presale 30+ is a fine score.

SafuYield.claim() (contracts/SafuYield.sol#902-909) ignores return value by token.transfer(_msgSender(),uint256(1000000000000000000)) (contracts/SafuYield.sol#908)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

SafuYield._decimals (contracts/SafuYield.sol#518) should be constant
SafuYield._name (contracts/SafuYield.sol#516) should be constant
