Struct ethers_signers::Ledger

pub struct Ledger { /* private fields */ }

Available on crate feature ledger and non-WebAssembly only.

A Ledger Ethereum App.

This is a simple wrapper around the Ledger transport

Implementations

impl LedgerEthereum

pub async fn new( derivation: DerivationType, chain_id: u64 ) -> Result<Self, LedgerError>

Instantiate the application by acquiring a lock on the ledger device.

use ethers_signers::{Ledger, HDPath};

let ledger = Ledger::new(HDPath::LedgerLive(0), 1).await?;

pub fn close(self)

Consume self and drop the ledger mutex

pub async fn get_address(&self) -> Result<Address, LedgerError>

Get the account which corresponds to our derivation path

pub async fn get_address_with_path( &self, derivation: &DerivationType ) -> Result<Address, LedgerError>

Gets the account which corresponds to the provided derivation path

pub async fn version(&self) -> Result<String, LedgerError>

Returns the semver of the Ethereum ledger app

pub async fn sign_tx( &self, tx: &TypedTransaction ) -> Result<Signature, LedgerError>

Signs an Ethereum transaction (requires confirmation on the ledger)

pub async fn sign_message<S: AsRef<[u8]>>( &self, message: S ) -> Result<Signature, LedgerError>

Signs an ethereum personal message

pub async fn sign_typed_struct<T>( &self, payload: &T ) -> Result<Signature, LedgerError>

where T: Eip712,

Signs an EIP712 encoded domain separator and message

pub async fn sign_payload( &self, command: INS, payload: &Vec<u8> ) -> Result<Signature, LedgerError>
