zkSync RPC connection via cURL

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

curl -X POST \
https://<YOUR_NODE_URL> \
-H "Content-Type: application/json" \
-H 'X-Auth-Token: <YOUR_AUTH_TOKEN>' \
-d '{"jsonrpc":"2.0", "id":2, "method": "YOUR_RPC_METHOD", "params": [YOUR_PARAMS] }'
  • Replace YOUR_NODE_URL with the node URL in the Blockdaemon app.
  • Replace YOUR_AUTH_TOKEN with the Auth Token in the Blockdaemon app.
  • Replace YOUR_RPC_METHOD with your chosen RPC method.
  • Replace YOUR_PARAMS with your selected RPC parameters.

zkSync 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:8443/websocket
  • Replace YOUR_AUTH_TOKEN with the Auth Token in the Blockdaemon app.
  • Replace YOUR_NODE_URL with the node URL in the Blockdaemon app.
