# Blockchain API Quick Start Guide

Once you are logged in to Launchpad, you will be able to set up your Blockchain API. To do so, follow the steps below.

## Subscription

Before you can create a new RPC endpoint, you will need a subscription.

To subscribe:

1. Verify that you are in the SaaS environment of Launchpad by checking the toggle button on the top right. You will easily recognize the SaaS environment by its light theme.\

3. In the subscription page, select the plan that fits your need. The "EW Member" plan is only available for enterprises that are [Energy Web members](broken://pages/Vg5FkW7TWZCnJoHKEizx#energy-web-members).\ <br>

   This will direct you to the endpoint creation page.

3. At the next step, under "**Security**" you can choose whether you want to set up JWT based security for your RPC endpoint. **Please note that you can require or disable this form of security at creation or later when managing your existing endpoints**.\

   If you choose JWT as a requirement, these are the steps to find the Token and Public Key you will need:

   a. Go to [www.jwt.io](http://www.jwt.io/)

   b. Select Algorithm as "**RS256**"

   c. You will see the following two sections: [Encoded](https://jwt.io/#encoded-jwt) and [Decoded](https://jwt.io/#decoded-jwt)

   d. You will find JWT token under Encoded and Public Key under Decoded<br>
4. Your RPC endpoint is ready! You can view and manage it by accessing "**Manage**" under **Blockchain API** in the left hand bar menu.<br>
