TKOToken._writeCheckpoint(address,uint32,uint256,uint256) (#1094-1112) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1104)
Don't use strict equality to determine if an account has enough Ether or tokens.

Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#449-455):
- (success) = recipient.call{value: amount}() (#453)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#528-554):
- (success,returndata) = target.call{value: weiValue}(data) (#537)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
