Get Started

Create Evercloud project and start your communication with blockchain

Registration

Go to https://dashboard.evercloud.dev/ and click "Register now!". Verify your e-mail and you will be taken to the dashboard.

Create a Project

Click "Create Project" and enter the name of your project

2. Click "Add project". You will see your project endpoints, analytics, security information and project settings:

Configure security

This is optional if you want to protect your endpoint with Basic Auth authorization.

Do not share your secret with anyone and store it safely.

Go to the "Security" tab and click toggle "Secret required"

You will see your secret appear in the "Summary" tab

Explore Playground

Click on the circle with arrow next to the endpoint to open GraphQL playground.

In the playground you can make queries and explore Graphql Schema.

First, you need to add your projectID to the url inside the playground to access it.

If you enabled "Secret required" option, then you need specify Basic Auth creds in the headers! You will find them on "Security" tab in Evercloud Dashboard.

Now lets execute this query to get the hash of the last masterchain block!

query{
  blockchain{
    blocks(last:1){
      edges{
        node{
          id
        }
      }
     }
  }
}

See the result
