Dfns Wallet for ethers.js v5

Dfns wallet integration with the popular ethers.js library version 5.x, makes working with Ethereum and other EVM compatible ecosystems as simple and painless as possible.

The DfnsWallet uses generateSignature to compute signatures using your Dfns managed wallets, for all the transactions created by your ethers.js program. Then you need to broadcast these transactions yourself to the corresponding node providers that are either self hosted or by a blockchain provider.

A typical setup routine looks like this,

import { DfnsWallet } from '@dfns/lib-ethersjs5'
import { DfnsApiClient } from '@dfns/sdk'
import { AsymmetricKeySigner } from '@dfns/sdk-keysigner'
import { JsonRpcProvider } from '@ethersproject/providers'

const rpcProvider = new JsonRpcProvider(process.env.RPC_PROVIDER_URL!)

const signer = new AsymmetricKeySigner({
  privateKey: process.env.DFNS_PRIVATE_KEY!,
  credId: process.env.DFNS_CRED_ID!,
  appOrigin: process.env.DFNS_APP_ORIGIN!,
})

const dfnsClient = new DfnsApiClient({
  appId: process.env.DFNS_APP_ID!,
  authToken: process.env.DFNS_AUTH_TOKEN!,
  baseUrl: process.env.DFNS_API_URL!,
  signer,
})

return new DfnsWallet({
  walletId: process.env.DFNS_WALLET_ID!,
  dfnsClient,
}).connect(rpcProvider)
