This repo contains a sample application for demonstration purposes only, walking through how to create sub-organizations, create private keys, and sign with the @turnkey/ethers signer, using passkeys. Please feel free to clone or fork this repo, or file an issue if there are improvements to be made! ❤️

The flow showcases 3 ways to make requests to Turnkey:

• the initial request to create a new sub-organization is authenticated in the NextJS backend with an API signature (using API_PUBLIC_KEY/API_PRIVATE_KEY from your .env.local file)
• the request to create a new ETH address is signed on the frontend with your passkey, but it's passed to the NextJS backend as a signed request (the body, stamp, and url are POSTed). This lets the backend submit this request on your behalf, and poll until the new "create private keys" activity completes. Once the activity completes it returns the new address to the frontend
• the request to sign a message is done 100% client-side via a Turnkey Ethers signer (see @turnkey/ethers): it's signed with your passkey, and submitted from the browser to the Turnkey API directly.

If you want to see a Viem demo with API keys instead of passkeys, head to the example with-ethers. A demo using passkeys with Viem can be found here. See our SDK repo for additional packages and examples.

Make sure you have Node.js installed locally; we recommend using Node v16 .

$ git clone https://github.com/tkhq/demo-ethers-passkeys.git
$ corepack enable  # Install `pnpm`
$ pnpm install # Install dependencies
$ pnpm run build  # Compile source code

The first step is to set up your Turnkey organization and account. By following the Quickstart guide, you should have:

• A public/private API key pair for Turnkey
• An organization ID

Once you've gathered these values, add them to a new .env.local file. Notice that your API private key should be securely managed and never be committed to git.

$ cp .env.local.example .env.local

Now open .env.local and add the missing environment variables:

• API_PUBLIC_KEY
• API_PRIVATE_KEY
• NEXT_PUBLIC_TURNKEY_API_BASE_URL
• NEXT_PUBLIC_ORGANIZATION_ID

$ pnpm run dev

This command will start a NextJS app on localhost. If you navigate to http://localhost:3000 in your browser, you can follow the prompts to create a sub organization, create a private key for the newly created sub-organization, and sign a message using your passkey with a ethers custom account!
