Cylum is a protocol designed to facilitate the construction of NFT and Meterverse projects on the Binance Smart Chain, as well as partnerships and funding. The CYM token is used to power and drive this ecosystem. In addition to our reward system, we have a unique lock-stake algorithm that provides each token holder with a reward of up to 400% annual percentage yield (APY) for staking $CYM.
Contract creator or owner is blacklisted for past scams
CYLUM.withdrawStuckToken(address,address) (#658-661) ignores return value by IERC20(token).transfer(recipient,IERC20(token).balanceOf(address(this))) (#660)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Low level call in Address.sendValue(address,uint256) (#336-342):
