Most Common Codes
| Code | Count | Example |
|---|---|---|
| W102 | 1 | function 'transfer' has 3 parameters, but NEP-17 requires 4: transfer(from, to, amount, data). The data parameter (type Any) is forwarded to the recipient's onNEP17Payment callback. |
| W103 | 1 | ERC-20 method(s) [approve, allowance, transferfrom] detected. These are not part of the NEP-17 spec; Neo uses Runtime.checkWitness() for authorization instead of the approve/allowance pattern. You may keep them as extensions, but they will not contribute to NEP-17 standard detection. |
| W106 | 1 | function 'supportsInterface' (EIP-165) is unnecessary on Neo N3. Neo uses the manifest 'supportedstandards' array for interface detection, which the compiler populates automatically. |
| W113 | 1 | Contract has transfer function but no onNEP17Payment callback. Other contracts cannot send tokens to this contract. |
