A SignatureProvider for communicating with eosjs from a Ledger device.
When plugged into eosjs, this signature provider enables applications to route signing requests to a Ledger device. Full instructions for eosjs can be found here.
EOSIO Labs repositories are experimental. Developers in the community are encouraged to use EOSIO Labs repositories as the basis for code and concepts to incorporate into their applications. Community members are also welcome to contribute and further develop these repositories. Since these repositories are not supported by Block.one, we may not provide responses to issue reports, pull requests, updates to functionality, or other requests from the community, and we encourage the community to take responsibility for these.
# Using yarn
yarn add eosjs-ledger-signature-providerconst { SignatureProvider } from 'eosjs-ledger-signature-provider'
const signatureProvider = new SignatureProvider()
signatureProvider.getAvailableKeys()
.then((result) => console.info('Keys: ', result))
.catch((error) => console.info('Error: ', error))
const chainId = '000000000'
const serializedTransaction = {} // A transaction as a Uint8Array. View `serializeTransaction` in https://github.com/EOSIO/eosjs/blob/develop/src/eosjs-api.ts
signatureProvider.sign({ chainId, serializedTransaction })
.then((result) => console.info('TransactionId: ', result))
.catch((error) => console.info('Error: ', error))const { Api, JsonRpc } from 'eosjs'
const { SignatureProvider } from 'eosjs-ledger-signature-provider'
const rpcEndpoint = 'https://localhost:3000'
const signatureProvider = new SignatureProvider()
const rpc = new JsonRpc(rpcEndpoint)
const api = new Api({ signatureProvider, rpc })
// eosjs will call both `getAvailableKeys` and `sign` from the SignatureProvider
api.transact(...)
