QuickNode Read-Only Endpoint Proof

Overview

Establish transport, authentication, chain identity, response shape, and tip movement with raw JSON-RPC before adding an SDK. This keeps the first proof deterministic and prevents a client-library configuration error from looking like an endpoint outage.

Prerequisites

• A secret reference for the QuickNode endpoint and token
• The expected chain, network, protocol, and chain identifier
• A non-sensitive read method supported by that chain

Instructions

Step 1: Inspect the integration

Use Read and Grep to find the endpoint variable, expected chain ID, timeout, and current client wrapper. Stop if source or logs contain a literal QuickNode token.

Step 2: Define the probe
