Metaegg working on web3 through NFT, Gaming, Entertainment, and DeFi. MEGG is a token made to support what’s next, controlled, and built on by the community. It will serve as a decentralized protocol layer for community-led initiatives that drive culture forward into the metaverse & gaming.
MetaeggDeFi._writeCheckpoint(address,uint32,uint256,uint256) (#1066-1084) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1076)
Don't use strict equality to determine if an account has enough Ether or tokens.

MetaeggDeFi.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#932-973) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,MEGG::delegateBySig: signature expired) (#971)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#440-446):
- (success) = recipient.call{value: amount}() (#444)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#519-545):
- (success,returndata) = target.call{value: weiValue}(data) (#528)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
