CoinOne._writeCheckpoint(address,uint32,uint96,uint96) (#262-273) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#265)
Don't use strict equality to determine if an account has enough Ether or tokens.

CoinOne.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#161-170) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,Token::delegateBySig: signature expired) (#168)
Avoid relying on block.timestamp.

CoinOne.getChainId() (#296-300) uses assembly
- INLINE ASM (#298)
Do not use evm assembly.

Constant CoinOne.totalSupply (#15) is not in UPPER_CASE_WITH_UNDERSCORES
Follow the Solidity naming convention.

CoinOne.slitherConstructorConstantVariables() (#4-302) uses literals with too many digits:
- totalSupply = 100000000e18 (#15)
Use: Ether suffix, Time suffix, or The scientific notation

delegate(address) should be declared external:
- CoinOne.delegate(address) (#148-150)
delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) should be declared external:
- CoinOne.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#161-170)
getPriorVotes(address,uint256) should be declared external:
- CoinOne.getPriorVotes(address,uint256) (#189-221)
Use the external attribute for functions never called from the contract.
