How to Connect to Polkadot

It’s easy to connect to your Polkadot infrastructure via RPC or WebSocket.

If you haven’t already configured any Polkadot infrastructure, visit the Polkadot marketplace page to learn more about Blockdaemon’s Polkadot options.

Once you have purchased your Blockdaemon Polkadot infrastructure, Your Blockdaemon Technical Account Manager (TAM) will send you the necessary access credentials. There are multiple ways to use these to connect to your node/cluster.

In this guide, we will cover the following simple methods of connection to your infrastructure:

Polkadot HTTP RPC Connection via cURL

Step 1 – Your TAM will send you the following access credentials:

  • Your Unique Endpoint URL
  • Your Unique Auth Token

Please Note: These are one-time view, so make sure to copy them.

Step 2 – Add your access credentials to a cURL request.

curl curl -H "Content-Type: application/json" \
-H "X-Auth-Token: YOUR_AUTH_TOKEN" \
-d '{"id":1, "jsonrpc":"2.0", "method": "YOUR_RPC_METHOD"}' \
https://YOUR_ENDPOINT_URL/http-rpc
  • Replace YOUR_ENDPOINT_URL with the Endpoint URL sent by your Blockdaemon TAM
  • Replace YOUR_AUTH_TOKEN with the Auth Token sent by your Blockdaemon TAM
  • Replace YOUR_RPC_METHOD with your chosen RPC method

Polkadot Connection via WebSocket

Step 1 – Your TAM will send you the following access credentials:

  • Your Unique Endpoint URL
  • Your Unique Auth Token

Please Note: These are one-time view, so make sure to copy them.

Step 2 – Add your access credentials to a websockets connection request:

wscat -H "X-Auth-Token: YOUR_AUTH_TOKEN" -c wss://YOUR_ENDPOINT_URL/websocket
    • Replace YOUR_ENDPOINT_URL with the Endpoint URL sent by your Blockdaemon TAM
    • Replace YOUR_AUTH_TOKEN with the Auth Token sent by your Blockdaemon TAM

Polkadot Connection via Sidecar API

Step 1 – Your TAM will send you the following access credentials:

  • Your Unique Endpoint URL
  • Your Unique Auth Token

Please Note: These are one-time view, so make sure to copy them.

Step 2 – Add your access credentials to a cURL request:

curl -X GET -H 'Content-Type: application/json' -H 'X-Auth-Token: YOUR_AUTH_TOKEN' 'https://YOUR_ENDPOINT_URL/YOUR_SIDECAR_ENDPOINT'
    • Replace YOUR_ENDPOINT_URL with the Endpoint URL sent by your Blockdaemon TAM
    • Replace YOUR_AUTH_TOKEN with the Auth Token sent by your Blockdaemon TAM
    • Replace YOUR_SIDECAR_ENDPOINT with your chosen REST endpoint
