VIKING [VikingSwap] 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

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

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