Expand description

Verifies an EIP-1271 isValidSignature(bytes32, bytes) call against a smart-contract wallet. Backed by the #759 EvmChain port when it lands; until then a venture wires its own implementation (e.g. an eth_call adapter) or the test-only StaticContractVerifier.

Required Methods§

Source

fn is_valid_signature<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, chain_id: &'life1 str, address: &'life2 str, message_hash: [u8; 32], signature: &'life3 [u8], ) -> Pin<Box<dyn Future<Output = Result<bool, ContractVerifierError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Whether the contract at address (on chain_id) approves signature for message_hash.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
