A decentralized social platform built on Solana with end-to-end encrypted messaging, creator tokens powered by Bags, and a fully gasless experience where users never pay a cent.
Shyft is a fully on-chain social platform. Every post, comment, like, follow, and chat message is a Solana transaction — stored permanently on-chain with no centralized database. Users sign in with their X account, get an instant embedded wallet through Privy, and start using the platform immediately. No seed phrases. No gas fees. No SOL required.
Creators can launch personal tokens directly inside Shyft using the Bags SDK. Fans trade them in-app, and every trade generates revenue that flows back through fee sharing.
Social
- On-chain profiles, posts, comments, reactions, reposts, and follows
- Real-time feed with auto-refresh and live engagement counters
- Clickable profiles and hover cards (like X/Twitter)
- Image uploads, GIF support, YouTube embeds, rich link previews
Messaging
- End-to-end encrypted 1:1 chat using NaCl Box (X25519 + XSalsa20-Poly1305)
- Key exchange and ciphertext stored on-chain — nobody can read your messages except you and the recipient
- In-chat SOL payments
Creator Tokens
- Launch personal tokens via Bags SDK with bonding curve pricing
- In-app trading — buy and sell creator tokens without leaving Shyft
- Fee sharing — creators earn passively as their community trades
- Earnings dashboard with claim flow
Gasless UX
- Treasury-sponsored transactions — platform pays all gas fees and account rent
- Users never need to own, buy, or hold any SOL
- Privy embedded wallets with silent signing — no wallet popups

Every instruction has a separate payer signer so the treasury can cover rent while the user only signs to prove identity.
Users never pay anything. Here's how:
- User signs in → Privy creates an embedded Solana wallet (0 SOL balance)
- User takes an action (post, chat, follow, etc.)
- Frontend builds the transaction with
feePayer = treasury - User's wallet signs to prove identity
- Transaction is sent to
/api/sponsor-txwhere the treasury co-signs - Treasury pays both the gas fee (~0.000005 SOL) and account rent (~0.003 SOL)
Cost per user: ~$0.001 at current SOL prices.
| Component | Technology |
|---|---|
| Key Derivation | Wallet signs a deterministic message → SHA-256 → X25519 keypair |
| Key Exchange | Public keys published on-chain as the first message in each chat |
| Encryption | NaCl Box (X25519-XSalsa20-Poly1305) with random 24-byte nonces |
| Storage | Ciphertext stored on-chain as Solana PDAs |
Each chat pair has a unique shared secret derived from Diffie-Hellman. Alice's chat with Bob uses a different shared secret than Alice's chat with Carol — full isolation between conversations.
