Veloran

The payment and access layer for the agent economy.

Sell APIs, datasets, and premium content that humans and AI agents unlock with USDC on Solana. Sellers receive 95% directly, settled on-chain by an Anchor program. Veloran never custodies buyer funds.

Hackathon status

Built for the Solana Frontier Hackathon, May 2026.

• ✅ Live on Solana devnet
• ✅ Human checkout via Privy email or Phantom wallet
• ✅ AI-agent unlock flow via HTTP 402 + X-PAYMENT
• ✅ Anchor settlement program deployed on devnet
• ✅ 95/5 seller/platform split enforced atomically on-chain
• ✅ Per-call unlocks and seller subscriptions
• ✅ Mainnet Anchor program deployed and smoke-tested; live app remains on devnet for hackathon recording

How it works

1. A seller signs in and publishes a paid resource: API-style JSON, dataset-shaped text, or premium analysis.
2. Human buyers open the public URL and unlock with Privy checkout.
3. AI agents call /api/x402/<slug>, receive HTTP 402 payment instructions, sign a Solana transaction, then re-request with X-PAYMENT.
4. The Anchor program transfers 95% to the seller and 5% to Veloran treasury in one atomic SPL-token settlement.
5. The app verifies the transaction and reveals the gated response. Each paid request creates a server-bound PaymentIntent with a 15-minute TTL and a memo of the form veloran:intent:<nonce>. The buyer's transaction must include that memo as a Memo program instruction. The server consumes the intent on the first successful unlock; replays return 409.

Closing line:

Publish once. Humans pay with checkout. Agents pay with HTTP 402. Sellers get paid directly on-chain.

Notes for judges

Veloran uses a custom exact-veloran HTTP 402 payment scheme for the hackathon demo. The app is x402-inspired and agent-readable, but the settlement path is intentionally Solana-native: a custom Anchor instruction verifies the price and executes the 95/5 split directly on-chain.
