|---|---|---|
| W111 | 2 | function 'onNEP17Payment' is marked payable, but Neo N3 has no native coin transfer; the modifier is accepted for compatibility but has no effect. Use onNEP17Payment(address, uint256, bytes) to handle incoming NEP-17 token payments. |
| RAW | 1 | [info][NEP-17] NEP-17 transfer method has 2 parameter(s), spec expects 4. See STANDARDS_MAPPING.md for details. |
| W101 | 1 | function 'transfer' has 2 parameters (ERC-20 pattern). NEP-17 requires 4 parameters: transfer(from, to, amount, data). The from address is verified via Runtime.checkWitness() and data (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. |
| W116 | 1 | function 'deposit' has payable modifier which has no effect on Neo N3. Use onNEP17Payment callback to receive token payments. |
