# Eip712VerificationResult

> Flutter Sealed Class

**Sealed Class**

Outcome of an EIP-712 proof verification attempt.

```dart theme={null}
sealed class Eip712VerificationResult
```

The sealed hierarchy lets callers distinguish between "the proof was
cryptographically verified", "the proof is structurally well-formed but
the full cryptographic check could not be completed", and the specific
reasons a proof was rejected.
