Prerequisites

An account management Snap set up.

Steps

1. Install the Keyring API

Install the @metamask/keyring-api module in your project directory using Yarn or npm:

yarn add @metamask/keyring-api

or

npm install @metamask/keyring-api

2. Create a KeyringSnapRpcClient

Create a KeyringSnapRpcClient:

import { KeyringSnapRpcClient } from "@metamask/keyring-api"
import { defaultSnapOrigin as snapId } from "../config"

let client = new KeyringSnapRpcClient(snapId, window.ethereum)

3. Call Account Management API methods

You can now use the KeyringSnapRpcClient to invoke Account Management API methods on your Snap.

For example, to call keyring_listAccounts:

const accounts = await client.listAccounts()
