  3. Click the BNB node.
  4. Click the Connect tab.

In the Connection Information section, you'll find the following:

BNB RPC connection via cURL

Use cURL to establish a BNB RPC connection with the following command:

curl -X POST -H 'Content-Type: application/json' --data '{"method": "YOUR_RPC_METHOD", "params": [YOUR_PARAMS], "id": 1}' 'YOUR_ENDPOINT_URL?auth=YOUR_AUTH_TOKEN'
  • Replace YOUR_RPC_METHOD with your chosen RPC method.
  • Replace YOUR_PARAMS with your selected RPC parameters.
  • Replace YOUR_ENDPOINT_URL with the Endpoint URL in the Blockdaemon app.
  • Replace YOUR_AUTH_TOKEN with the Auth Token in the Blockdaemon app.

BNB Connection via WebSocket

Add your access credentials to a WebSocket connection request:

wscat -H "X-Auth-Token: YOUR_AUTH_TOKEN" -c wss://YOUR_ENDPOINT_URL/websocket 



wscat is a tool that can connect over WebSocket(s) and may need to be installed. You can use your preferred tool of choice.
