By Severity
| Severity | Count |

| warning | 1130 |
Most Common Codes
| Code | Count | Example |
|---|---|---|
| W200 | 1020 | function 'tryRecover' in 'ERC2771Context' overrides 'Context::tryRecover' which is not marked 'virtual' |
| INVALID_STORAGE_RETURN | 59 | function 'getAddressSlot' return value 'AddressSlot' uses 'storage' data location (treated as Any) |
| W121 | 45 | duplicate constant state variable 'GENERIC' detected while merging libraries |
| W111 | 2 | function 'execute' 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. |
| W116 | 2 | function 'execute' has payable modifier which has no effect on Neo N3. Use onNEP17Payment callback to receive token payments. |
| MANIFEST_WILDCARD_CONTRACT | 1 | contract 'ERC2771Forwarder' requires wildcard contract manifest permissions (contract='*') due to dynamic contract calls. This is riskier than fixed contract hashes; use --deny-wildcard-contracts to make this a hard error. |
| VALIDATION_WARNING | 1 | 'using X for *' is supported; all library functions are available but type-specific filtering is not enforced at compile time |
