Federated Keyless Integration Guide

Step 1. Setup your IAM provider

Set up your project with your IAM to match the account structure you are looking for.

Step 2. Register the JSON Web Key Set (JWKS) on-chain

Federated Keyless accounts require the JWKS to be registeed on-chain.

To register the JWKS - call the 0x1::jwks::update_federated_jwk_set entry function with an Aptos account that will store the JWKs that will be used to validate transactions signed by federated keyless accounts.

The JWK set can be found as follows -

AWS Cognito - https://cognito-idp.<region>.amazonaws.com/<userPoolId>/.well-known/jwks.json

Auth0 - https://<yourDomain>/.well-known/jwks.json

The typescript SDK contains functionality to simplify the process given the issuer for your IAM provider setup (the iss claim value on your user’s JWT tokens).

import {Aptos} from '@aptos-labs/ts-sdk'; // Requires version v1.29.1 or later
 
const aptos = new Aptos(new AptosConfig({ network: Network.DEVNET })); // Configure your network here
const alice = // Derive your Aptos account here
const jwkTxn = await aptos.updateFederatedKeylessJwkSetTransaction({ sender: alice, iss });
await aptos.signAndSubmitTransaction({ signer: alice, transaction: jwkTxn });

You can use the interactive example provided by the SDK to easily register the JWKS for your IAM provider in devnet or testnet. This will setup the JWK owner account with a Google Keyless account.

git clone https://github.com/aptos-labs/aptos-ts-sdk
cd aptos-ts-sdk
pnpm install && pnpm build
cd examples/typescript
pnpm install
pnpm jwk_update

To setup the JWK owner account in mainnet, you will need create an account and use it to register the JWKS.
