Get keys bound to a wallet address

While most Open Payments code snippets are intended for clients, getting the keys bound to a wallet address is primarily a function of account servicing entities.

When an authorization server receives a signed grant request, the server can make a call to acquire the public keys bound to the wallet address. Then, when a client makes a request to a resource server, the resource server calls the auth server to ensure the signature of the request corresponds to the public JWK of the wallet address. This enables the server to ensure the client is who it says it is.

These code snippets get the keys associated with the specified wallet address.

Before you begin

We recommend creating a wallet account on Rafiki.Money, a test wallet provider that’s part of the Interledger testnet. Creating an account allows you to test your client against the Open Payments APIs by using an ILP-enabled wallet funded with play money.

Additional configuration

Add "type": "module" to package.json

Add the following to tsconfig.json

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "ES2022"
  }
}

Get started

Import dependencies

import { createAuthenticatedClient } from "@interledger/open-payments";

Initialize Open Payments client

const client = await createAuthenticatedClient({
  walletAddressUrl: WALLET_ADDRESS,
  privateKey: PRIVATE_KEY_PATH,
  keyId: KEY_ID,
});

Get wallet address keys

const walletAddressKeys = await client.walletAddress.getKeys({
  url: WALLET_ADDRESS,
});

Output

console.log("WALLET ADDRESS KEYS:", JSON.stringify(walletAddressKeys, null, 2));

Run tsx path/to/directory/index.ts.
