ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#1316-1338) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1318)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#724-730):
- (success) = recipient.call{value: amount}() (#728)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#785-792):
- (success,returndata) = target.call{value: value}(data) (#790)
Low level call in Address.functionStaticCall(address,bytes,string) (#810-816):
- (success,returndata) = target.staticcall(data) (#814)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
