AMPLE [AmpleSwap] Token

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

AmpleToken._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.

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

- Version used: ['>0.6.6', '>=0.4.0', '>=0.6.0<0.8.0', '>=0.6.6']
- >=0.6.0<0.8.0 (#1)
- >=0.6.0<0.8.0 (#24)
- >=0.4.0 (#91)
- >=0.4.0 (#188)

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#508-534):
- (success,returndata) = target.call{value: weiValue}(data) (#517)
Low level call in Address.sendValue(address,uint256) (#429-435):
- (success) = recipient.call{value: amount}() (#433)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
