How to build a wallet

This guide shows how to build either an WebExtension Wallet or a iFrame-based Wallet.

WebExtension wallet

The full implementation of this example can be found here:

• WebExtension Wallet Example

Note:

• If you want to see a more advanced implementation you can take a look into the repository of the Superhero Wallet

1. Create bridge between extension and page

First you need to create a bridge between your extension and the page. This can be done as follows:

// import { AeSdkAepp, Node } from '@aeternity/aepp-sdk';


const TESTNET_NODE_URL = 'https://testnet.aeternity.io';
const MAINNET_NODE_URL = 'https://mainnet.aeternity.io';
const COMPILER_URL = 'https://compiler.aepps.com';

2. Initialize AeSdkWallet class

Then you need to initialize AeSdkWallet class in your extension and subscribe for new runtime connections. After the connection is established you can share the wallet details with the application.

iFrame-based Wallet

The iFrame-based approach works similar to the WebExtension approach except that the connectionProxy in between isn't needed.

You can take a look into the implementation of the following example to see how it works:
