    fn is_signer_for(&self, addr: &Address) -> bool { ... }
}

An Ethereum Signer used via RPC.

Required Methods

fn accounts(&self) -> Vec<Address>

Returns the available accounts for this signer.

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, address: Address, message: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Signature>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the signature

fn sign_transaction<'life0, 'life1, 'async_trait>( &'life0 self, request: TransactionRequest, address: &'life1 Address, ) -> Pin<Box<dyn Future<Output = Result<T>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

signs a transaction request using the given account in request

fn sign_typed_data( &self, address: Address, payload: &TypedData, ) -> Result<Signature>

Encodes and signs the typed data according EIP-712. Payload must implement Eip712 trait.

Provided Methods

fn is_signer_for(&self, addr: &Address) -> bool

Returns true whether this signer can sign for this address
