Example: with-zerodev-aa

This example shows how to construct and broadcast a transaction using Turnkey with Ethers (WIP), Viem, and Zerodev.

If you want to see a demo with passkeys, it's coming 🔜™️!

Getting started

1/ Cloning the example

Make sure you have Node.js installed locally; we recommend using Node v18+.

$ git clone https://github.com/tkhq/sdk
$ cd sdk/
$ corepack enable  # Install `pnpm`
$ pnpm install -r  # Install dependencies
$ pnpm run build-all  # Compile source code
$ cd examples/with-zerodev-aa/

2a/ Setting up Turnkey

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
  • A Turnkey wallet account (address), private key address, or a private key ID

2b/ Setting up ZeroDev

The next step is to navigate to ZeroDev to create an account. Visit the ZeroDev Dashboard to create a paymaster and find your bundler RPC. You can find more details on the tutorial page here: https://docs.zerodev.app/sdk/getting-started/tutorial.

Once you've gathered these values, add them to a new .env.local file. Notice that your 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
  • BASE_URL
  • ORGANIZATION_ID
  • SIGN_WITH -- a Turnkey wallet account address, private key address, or private key ID. If you leave this blank, we'll create a wallet for you.
  • ZERODEV_RPC

3/ Running the scripts

Note: only Viem is supported in this example at this time. Ethers is currently a WIP.

These scripts construct transactions via Turnkey and broadcast them via Infura. If the scripts exit because your account isn't funded, you can request funds on https://sepoliafaucet.com/, via Coinbase Wallet, etc.

Viem

$ pnpm start-viem

This script will do the following:

  1. instantiate a Turnkey Viem wallet client
  2. instantiate a Viem public client (to be used to fetch onchain data)
  3. create a ZeroDev Validator
  4. create a ZeroDev Kernel Client (with Paymaster support)
  5. send a UserOp to mint an NFT

See the following for a sample output:
