Introducing Backend Wallets

Winston Yeo

We are thrilled to announce support for backend wallets! This enhancement empowers developers to programmatically access wallets through their backend systems without needing to manage private keys directly. It simplifies wallet management while maintaining security and flexibility for various use cases.

Traditionally, managing wallets in decentralized applications often required dealing with private keys or relying on client-side solutions. However, there are scenarios where programmatic access to wallets on the backend is essential, such as:

• Server-side automation: Automating blockchain interactions for services like token minting, payments, or data signing.
• Enhanced security: Keeping private keys off the client side while enabling wallet operations.
• Custom integrations: Integrating wallets seamlessly with backend APIs for complex workflows.

With backend wallet support, developers can now securely and conveniently access wallets from their backend infrastructure.

The new feature allows you to create a wallet instance on the backend using the backend, here's how it's done with the typescript SDK:

import { inAppWallet } from "thirdweb/wallets";
 
const wallet = inAppWallet();
const account = await wallet.connect({
  strategy: "backend",
  client: createThirdwebClient({
    secretKey: "...", // Your backend client secret key
  }),
  walletSecret: "...", // Your unique wallet secret. Each secret corresponds to a single wallet
});
console.log("account.address", account.address);
