ACE [BURNACE] Token

Contract creator or owner is blacklisted for past scams

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

burnace.withdraw(uint256)._owner (#777) shadows:
- Ownable._owner (#638) (state variable)
Rename the local variables that shadow another component.

burnace.buyToken(address) (#724-740) performs a multiplication on the result of a division:
-_tkns = (sPrice * _eth) / 1000000000000000000 (#730)
-_burnamt = ((_tkns * 150) / 100) (#731)
Consider ordering multiplication before division.

burnace.beginClaim(uint256,uint256,uint256,uint256) (#754-760) should emit an event for:
- aSBlock = _aSBlock (#755)
- aEBlock = _aEBlock (#756)
- aAmt = _aAmt (#757)
- aCap = _aCap (#758)
burnace.beginBuy(uint256,uint256,uint256,uint256,uint256) (#761-768) should emit an event for:
- sSBlock = _sSBlock (#762)
- sEBlock = _sEBlock (#763)
- sChunk = _sChunk (#764)
- sPrice = _sPrice (#765)
- sCap = _sCap (#766)
Emit an event for critical parameter changes.

burnace.withdraw(uint256)._owner (#777) lacks a zero-check on :
- _owner.transfer(amount) (#778)
Check that the address is not zero.
