Dfns Wallet for Polymesh

Dfns wallet integration with Polymesh SDK (https://developers.polymesh.network/sdk-docs/), makes working with Polymesh as simple and painless as possible. DfnsWallet implements the official polkadot signer interface and we provide a DfnsSigningManager implementing the official signing manager interface to be used in the PolymeshSDK

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-polymesh'
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!,
})

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
