Expand description

Network-agnostic signing: messages, typed data, and hashes.

Required Methods§

Source

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

returns the available accounts for this signer

Source

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

Returns the signature

Source

fn sign_typed_data<'life0, 'life1, 'async_trait>( &'life0 self, address: Address, payload: &'life1 TypedData, ) -> Pin<Box<dyn Future<Output = Result<Signature, BlockchainError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Encodes and signs the typed data according EIP-712. Payload must conform to the EIP-712 standard.

Source

fn sign_hash<'life0, 'async_trait>( &'life0 self, address: Address, hash: B256, ) -> Pin<Box<dyn Future<Output = Result<Signature, BlockchainError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Signs the given hash.

Provided Methods§

Source

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

Returns true whether this signer can sign for this address
