ArenaSwap is a decentralized exchange platform built on BSC (Binance Smart Chain) that focuses on gamification of yield farming and gambling.
Our vision is to make DeFi and yield farming mainstream through gamification and storytelling, creating an ecosystem that supports the value of our token and NFTs.
We implement powerful deflationary mechanisms to safeguard the token value. Gamified gambling and an NFT collectible game are developed as part of the ecosystem to achieve this.

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
