Name

Cap

One-liner

Spending ceilings for AI agents. One Solana deposit, off-chain Hyperliquid packets, one settlement.

Description

Harbor Labs opens an $8 USDC payment channel on Solana. Scout, an overnight agent, buys Hyperliquid mark packets as 50-byte Ed25519 vouchers. It cannot open, settle, or exceed the cap. Unused USDC returns when Priya seals the channel. Replay of the same voucher pays nothing.

Buyer

Head of Ops at a crypto research desk. They already pay for Hyperliquid marks and LLM briefs. They will not give an overnight agent a vendor API key, and they will not sign a chain tx per packet.

Pricing

Seat $99/mo is the first invoice. 50 bps on distribute is the scale line. Demo channel $8 (cents of take). Production $500–$5,000. At $10k/mo agent spend: ~$50 take + $99 seat.

Go-to-market

Beachhead: crypto research desks already paying for marks and LLM briefs. $8 is the demo ceiling, not ACV. Charge $99/mo for the desk (who may open and settle), plus 50 bps on distribute when production channels are $500–$5,000. Compose with pay-kit so any 402 route sits behind a human-held ceiling. Zero paying users this week — public desk is the proof.

Traction (true)

Zero revenue. Zero LOIs. Public replay at /desk?play=1, public GitHub, npm test with no keys, weekly one-minute videos. No token. No extra chain.

Next 30 days
