report
Token seems to be legit.

BSWToken._writeCheckpoint(address,uint32,uint256,uint256) (#1227-1245) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1237)
Don't use strict equality to determine if an account has enough Ether or tokens.

Low level call in Address.sendValue(address,uint256) (#392-398):
- (success) = recipient.call{value: amount}() (#396)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#471-497):
- (success,returndata) = target.call{value: weiValue}(data) (#480)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
