xChat Native

xChat Native is the original JettChat experience: sign in with X, connect a Solana wallet (or pay $8.88), get end-to-end encrypted chat with gaze cursor typing. It's the lowest-friction path into the JettChat product.

Implementation: jettoptx/joe-jettchat-app + @jettoptx/auth.

OAuth flow

Sign-in uses X/Twitter OAuth 2.0 PKCE with the following scopes:

• tweet.read, tweet.write
• users.read
• dm.read, dm.write
• offline.access

After the authorization-code exchange:

1. The auth route generates a fresh PKCE code verifier/challenge.
2. On callback, the SDK exchanges the code for tokens.
3. An Ed25519 JWT is signed by @jettoptx/auth and dropped into the jettauth httpOnly cookie.
4. The X profile is cached in a separate client-readable x_profile cookie.

JTX gate

After sign-in, JettChat's middleware enforces JTX access on protected routes. The four code-level tiers map onto the three staking tiers:

A 30-day Stripe-backed basic gate is available at $8.88 for users without JTX. See Token / Subscriptions.

What's wired up

• ✅ X OAuth 2.0 PKCE end-to-end
• ✅ Solana JTX balance check via Helius RPC
• ✅ Ed25519 JWT cookie sessions
• ✅ AGT Gaze Triad biometrics (shared with Phantom Mode)
• ✅ Stripe and Tempo CLI fallback payment rails
• ✅ Founder bypass wallet for protocol treasury

Phantom Mode contrast

If you need maximum privacy and metadata resistance — Tor-only transport, post-quantum crypto, hardware-backed keys, duress PIN with cryptographic wipe — use Phantom Mode instead. xChat Native is optimized for speed of onboarding and public networks; Phantom Mode is optimized for adversarial environments.
