Getting Started with QuickNode

Let’s get started and see how easy and painless it is to create an RPC endpoint in just a few minutes. To build on any of QuickNode’s supported blockchains, you'll need an API endpoint to connect with the network. Let’s follow a few short steps to create our custom endpoint:

Go to https://QuickNode.com/ and click “Create account”

Enter your information and click the button to “Create a free account”

Next, specify which type of project you are building. Choose “Other” and enter scan node.

Once you click “Finish,” you’ll see this screen. You’ll need to check your email inbox to complete the next step.

Check your email to verify your QuickNode account. Click “Verify Your Account”

Clicking verify in the above email will take you back to the developer portal. Next, you’ll click “Create an endpoint.”

Select the chain you’d like to build on.

And select the network

Next, you’ll be prompted to select add-ons from the QuickNode Marketplace to add. There are many free add-ons available to supercharge your dApp — along with several paid add-ons from industry leaders.

This step is optional. You can continue without selecting any add-ons.

Next, select a plan. Choose the “Build” plan to apply your discount.

Finalize your Build plan and enter your coupon code “Forta20” here before completing your purchase (don’t add the quotes into the coupon section, just Forta20).

Select your endpoint.

From here, you’ll need to grab the RPC URL required to set up your Forta node.

You can copy the HTTP Provider or WSS Provider URL to use in your web3 application. On your endpoint's page, you can view Metrics, manage Add-ons, and control Security features such as token authentication, JSON Web Tokens (JWT), referrer whitelisting, and more.

Now that you have your HTTPS RPC URL, we’ll need to connect QuickNode to the Forta scan node running on your terminal.

Configure your QuickNode Chain APIs

If you haven’t already installed Forta on your terminal, make sure to go through the quickstart guide for kickstarting your Forta scan node.

Once your Forta directory has been initialized, you’ll find a file named  config.yml. We’ll need to configure that file so that our scan node knows how to pull data from the blockchain.

Forta detection bots are able to call JSON-RPC APIs using the RPC endpoints and the chain ID configured in the config.yml file, to do so, we’ll need to initialize the scan.jsonRpc.url property in the config.yml file, with the QuickNode HTTP RPC URL from your account.

Open the config.yml file in your Forta directory, and copy your QuickNode RPC URL in the jsonRpc property:

chainId: 1

scan:
  jsonRpc:
    url: https://{Your QuickNode RPC URL}

That’s it! Your Forta node will now scan blockchain transactions at lightning speed using QuickNode’s Core API.

Please note that we’ve set the chainId property to one in the above code. This is because we provided guidance to create an Ethereum application, and the Ethereum Mainnet chain ID is one.

If you want to scan other chains like Polygon, Arbitrum, or Optimism, please refer to the following section!
