Dfns Wallet for Polkadot

Dfns wallet integration with Polkadot{.js} (https://polkadot.js.org/docs/api/start), makes working with Polkadot 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 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-polkadot'
import { DfnsApiClient } from '@dfns/sdk'
import { AsymmetricKeySigner } from '@dfns/sdk-keysigner'

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 DfnsWallet.init({
  walletId,
  dfnsClient,
})
Copy
