Scalar Field – Robinhood Bridge

About

Scalar Field – Robinhood Bridge is a minimal, background-only Chrome extension that completes the Robinhood OAuth login flow for the Scalar Field trading platform.

When Robinhood redirects its authentication callback to localhost:15051, this extension detects it, captures the URL parameters, and securely posts them to Scalar Field — finishing the login handshake with no manual steps required.

FEATURES
- No popup, no UI, no settings — installs and works silently
- Manifest V3 service worker architecture
- Activates only on localhost:15051 — no other tabs or sites are touched
- Does not store, log, or share any personal data
- Required companion for Scalar Field's Robinhood trading integration

PERMISSIONS EXPLAINED
- localhost:15051 — listens for the Robinhood OAuth redirect
- scalarfield.io — forwards the callback to complete authentication

This extension is intended for Scalar Field users who have connected their Robinhood account and need the browser-side OAuth bridge to function correctly.
