ARENA Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

ArenaToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/ArenaToken.sol#212-230) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/ArenaToken.sol#222)
Don't use strict equality to determine if an account has enough Ether or tokens.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

BEP20._approve(address,address,uint256).owner (contracts/libs/BEP20.sol#280) shadows:
- Ownable.owner() (@openzeppelin/contracts/access/Ownable.sol#35-37) (function)
Rename the local variables that shadow another component.

ArenaToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/ArenaToken.sol#78-119) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,ARENA::delegateBySig: signature expired) (contracts/ArenaToken.sol#117)
Avoid relying on block.timestamp.

ArenaToken.getChainId() (contracts/ArenaToken.sol#237-241) uses assembly
