Usage

This package implements the TransactionSigner interface from blockstack.js using Ledger's Bitcoin application.

This provides both single-sig and multi-sig signers.

To use:

import { LedgerSigner } from 'blockstack-ledger'
import bsk from 'blockstack'
import Transport from '@ledgerhq/hw-transport-node-hid'

const signer = new LedgerSigner(`m/44'/88'/0'/0/1`, Transport)
bsk.makeTokenTransfer(recipientAddress, 'STACKS', BigInteger.fromHex('10'), '', signer)
    .then((signedTX) => ...)

Building

This library, unfortunately, depends on a fork of the Ledger Bitcoin API. This is because the original API does not expose the ability to sign a subset of inputs in the transaction (e.g., if you want a transaction to have three inputs, where only one of the inputs is signed by the Ledger, but the other inputs are signed by other parties).

Testing

Until I can figure out how to get the APDU mocking working correctly with ledgerjs, you'll need a device to test with. That device should be initialized with this seed phrase:
