This quickstart will guide you through Turnkey’s onboarding, adding an API key, creating a wallet, and signing your first Ethereum transaction.

Create your Turnkey Organization

  • Visit and enter your email address
  • Confirm your email by clicking on the link inside of the confirmation email
  • Follow the prompts to add your first authenticator and create your organization

Find your Organization ID

All API requests require an organization ID. Yours can be located in the user dropdown menu at the top right corner of the dashboard.

Find organization ID

For convenience, it's worth setting this as a permanent shell variable:

export ORGANIZATION_ID="<Your Org ID>"

Add an API key

Turnkey API Keys are generic public / private key pairs that allow you to make requests to our API. To generate a new key pair, we'll use the Turnkey CLI.

Installing turnkey

brew install tkhq/tap/turnkey

We are employing Homebrew in this guide as a quick and easy install path. For an installation path that requires no trust in external parties, refer to our CLI repo.

Generate an API key

turnkey generate-api-key --organization $ORGANIZATION_ID --key-name quickstart

When you run this command, Turnkey’s CLI generates an API key pair and stores the API private key locally. Copy the publicKey field in the output. In the next step, we'll add this to our User.

Add your public API key

Navigate to your user page by clicking on "User Details" in the user dropdown menu.

Find user details

Click on "Create API keys" and follow the prompts to add the generated public API key. You'll be required to authenticate with the same authenticator used during onboarding. After this succeeds, you should be all set to interact with our API.

NOTE: if you would like to manually your locally stored public/private API key files (e.g. key.public, key.private), you will have to save the files without newlines (which occupy extra bytes). For example, for VIM, use :set binary noeol or :set binary noendofline before writing.

Create a Wallet

Wallets are collections of cryptographic key pairs typically used for sending and receiving digital assets. To create one, we need to provide a name:

turnkey wallets create --name default --key-name quickstart

Create an Ethereum account

To create a cryptographic key pair on our new Wallet, we need to pass our desired address format:

turnkey wallets accounts create --wallet default --address-format ADDRESS_FORMAT_ETHEREUM --key-name quickstart

This command will produce an Ethereum address (e.g. 0x08cb1216C95149DF66978b574E484869512CE2bF) that we'll need to sign a transaction. You can see your new Wallet account with:

turnkey wallets accounts list --wallet default --key-name quickstart

Sign a Transaction

Now you can sign an Ethereum transaction with this new address with our sign_transaction endpoint. Make sure to replace the unsignedTransaction below with your own. You can use our simple transaction generator if you need a quick transaction for testing:

turnkey request --path /public/v1/submit/sign_transaction --body '{
"timestampMs": "'"$(date +%s)"'000",
"organizationId": "'"$ORGANIZATION_ID"'",
"parameters": {
"signWith": "<Your Ethereum address>",
"unsignedTransaction": "<Your Transaction>"
}' --key-name quickstart

If you'd like to broadcast your transaction, you can easily do so via Etherscan.
