TAU.setLiquidPair(address)._lp (contracts/TAU.sol#273) lacks a zero-check on :

TAU.antiWhale(address,address,uint256) (contracts/TAU.sol#210-255) uses timestamp for comparisons
Dangerous comparisons:
- traders[_recipient][BUY].lastTrade + buyCooldown > curTime (contracts/TAU.sol#225)
- traders[_sender][SELL].lastTrade + sellCooldown > curTime (contracts/TAU.sol#242)
Avoid relying on block.timestamp.
