Ensure that a verified contract satisfies the following high-level requirements:
- The implemented token follows the security standards.
Category “V10” lists requirements related to the token of the smart contracts.
| # | Description |
|---|---|
| 10.1 | Verify that the token contract follows a tested and stable token standard. |
| 10.2 | Use the approve function from the ERC-20 standard to change allowed amount only to 0 or from 0. |
| 10.3 | Verify that the contract does not allow to transfer tokens to zero address. |
| 10.4 | Verify that the re-entracy attack has been considered when using the token contracts with callbacks (e.g. ERC-777). |
| 10.5 | Verify that the transfer business logic is consistent, especially when re-sending tokens to the same address (msg.sender == destination). |
| 10.6 | Verify that there are no vulnerabilities associated with Token. |
