Basic Attention Token (BAT) Smart Contract Risk
No Revert on Transfer Failure
⚠ HIGH severityVulnerability
BAT returns false on failure instead of reverting. If the return value is not checked, failed transfers will silently succeed, leading to accounting errors or fund loss.
Related: Unchecked Return Values
Safe integration
Always check the boolean return value of transfer/transferFrom, or use SafeERC20 which reverts on false returns.
