BNBVerse [Binance Verse] Token

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

BinanceVerse._writeCheckpoint(address,uint32,uint256,uint256) (BinanceVerse.sol#269-287) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (BinanceVerse.sol#279)
Don't use strict equality to determine if an account has enough Ether or tokens.

BEP20Extended._transfer(address,address,uint256) (BEP20Extended.sol#300-323) contains a tautology or contradiction:
- _balances[sender].sub(amount).sub(receiedAmount) < 0 (BEP20Extended.sol#315)
Fix the incorrect comparison by changing the value type or the comparison.

BinanceVerse.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (BinanceVerse.sol#80-104) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,INVALID_EXPIRATION) (BinanceVerse.sol#91)
BinanceVerse.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (BinanceVerse.sol#135-176) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,BNBVerse::delegateBySig: signature expired) (BinanceVerse.sol#174)
Avoid relying on block.timestamp.
