QuickNode Endpoint Hardening

Overview

Protect endpoint tokens as credentials, isolate consumers with multiple tokens, and layer only controls that match the client threat model. A browser referrer rule is not a substitute for keeping privileged RPC or account keys on a server.

Prerequisites

• Endpoint inventory with owners, applications, and environments
• Current plan and available endpoint-security controls
• A threat model covering browser, server, CI, and operator access

Instructions

Step 1: Find exposure

Use Read and Grep for quiknode.pro, x-token, x-api-key, JWT configuration, logs, examples, and client bundles. Stop and rotate any live credential committed to Git or shipped to an untrusted client.

Step 2: Separate identities
