DelegateERC20._writeCheckpoint(address,uint32,uint256,uint256) (#1232-1250) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1242)
Don't use strict equality to determine if an account has enough Ether or tokens.

DelegateERC20.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#1096-1137) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,MdxToken::delegateBySig: signature expired) (#1135)
Avoid relying on block.timestamp.

Pragma version^0.6.0 (#2) allows old versions
Pragma version^0.6.0 (#1035) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.sendValue(address,uint256) (#373-379):
- (success) = recipient.call{value: amount}() (#377)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#439-460):
- (success,returndata) = target.call{value: weiValue}(data) (#443)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
