# Sign Up to use ChainAPI

Table of Contents

ChainAPI identifies you through a wallet you own by way of MetaMask (opens new window). Other wallets will be supported in the future. ChainAPI will ask you to sign a message (from within MetaMask) for a particular wallet account proving your ownership of the account. For the first time you connect, you will be prompted for your email address which will be linked to a ChainAPI account. Each time you return to ChainAPI you will connect again, using MetaMask, to identify yourself by signing a message for the same account.

# Connecting

If you are an existing MetaMask user, it is recommended that you create a separate (dedicated) MetaMask wallet specifically for ChainAPI using a new seed phrase known in MetaMask as a "Secret Recovery Phrase". In the future ChainAPI will offer services allowing control of your Airnode via the ChainAPI UI. A separate dedicated wallet will help streamline these features.

  1. Connect: Click on the Connect With MetaMask button (or alternatively use Log In Using MetaMask) to create a new account and register and email address. If you do not have MetaMask installed you will be prompted to do so.


  1. Create Wallet: (new MetaMask installations only) - If you have just installed MaskMask, it will open a web page to create or open an existing wallet.

    Once the new wallet is created, return to the ChainAPI landing page, refresh it and select the Connect With Metamask button again.

  1. Signature Request: When MetaMask opens you may be asked to select an account before the signature request prompt appears. For newly created wallets there will only be one account, the default account though others can be added. For existing wallets select which account you would like to use. Remember the account you select.

    You will be prompted to authorize a signature request which does not require any cryptocurrency. By signing this request, you prove ownership of the wallet account.


  1. Register Email: (first time connecting) After the MetaMask popup closes you may be prompted for your email address if the MetaMask account you selected is not recognized by ChainAPI. ChainAPI associates your email address with your MetaMask wallet account for future communications. Enter your email, wait a moment for it verification, then select the Confirm Email button.

    An email will be sent to you asking you to confirm ownership of the email address. After performing the confirmation ChainAPI should show its Getting Started page.

# Subsequent Connecting

Be sure to use same account each time you use the Connect With MetaMask button. Opening MetaMask will show you the account currently selected.
