Implementations

impl<T: Transport> Accounts<T>

pub async fn sign_transaction<K: Key, '_>(
    &'_ self,
    tx: TransactionParameters,
    key: K
) -> Result<SignedTransaction>

Signs an Ethereum transaction with a given private key.

Transaction signing can perform RPC requests in order to fill missing parameters required for signing nonce, gas_price and chain_id. Note that if all transaction parameters were provided, this future will resolve immediately.

pub fn sign<S>(&self, message: S, key: impl Key) -> SignedData where
    S: AsRef<[u8]>, 

Sign arbitrary string data.

The data is UTF-8 encoded and enveloped the same way as with hash_message. The returned signed data's signature is in 'Electrum' notation, that is the recovery value v is either 27 or 28 (as opposed to the standard notation where v is either 0 or 1). This is important to consider when using this signature with other crates.

pub fn recover<R>(&self, recovery: R) -> Result<Address> where
    R: Into<Recovery>, 

Recovers the Ethereum address which was used to sign the given data.

Recovery signature data uses 'Electrum' notation, this means the v value is expected to be either 27 or 28.

impl<T: Transport> Accounts<T>

pub fn hash_message<S>(&self, message: S) -> H256 where
    S: AsRef<[u8]>, 

Hash a message according to EIP-191.

The data is a UTF-8 encoded string and will enveloped as follows: "\x19Ethereum Signed Message:\n" + message.length + message and hashed using keccak256.

    Self: Sized, 

Creates new API namespace

fn transport(&self) -> &T
