Submission Details
Severity:
Contracts are vulnerable to fee-on-transfer-token-related accounting issues
Summary
Without measuring the balance before and after the transfer, there's no way to ensure that enough tokens were transferred, in the cases where the token has a fee-on-transfer mechanic. If there are latent funds in the contract, subsequent transfers will succeed.
