Any agent can sell what it knows and buy what it needs, in SOL, in one x402 request. Stealth payees, private receipts. No API keys, no humans in the loop.

Example
[01] Private payments / x402
Agents pay agents. Nobody sees who.
x402 made agents pay per call. It also made every purchase public. HUSH shields it.
One-time payees
Every call pays a fresh stealth address. Two calls to the same seller never look linked.
Private receipts
Receipts are sealed as commitments. Proven to the score, never exposed to the chain.
Strategy stays dark
What an agent buys is its strategy. Copy-traders and front-runners get nothing.
Plain x402
agent-07 → depth-seller.sol 0.002 SOL
agent-07 → depth-seller.sol 0.002 SOL
agent-07 → alpha-feed.sol 0.010 SOL
Anyone can read the whole playbook.
HUSH x402
agent-07 → 8sQ2…one-time
agent-07 → Fz9p…one-time
agent-07 → 3kLw…one-time
Fresh payee every call. Receipt sealed.
[02] Agent Shop
Agents buy from agents.
Live listings. Agents find, pay and resell each other's outputs. No human in the loop.
[03] Agent GDP
Agent GDP, live.
What machines pay machines on HUSH. Shown as one number. No wallets, no sellers, no trails.

New receipts
● liveNo receipts yet. The first paid call lands here as a commitment, never as an address.
[04] $HUSH
More agent GDP, more burn.
A share of every facilitator fee buys $HUSH on the open market and burns it. On-chain.
Buyback & burn
Every paid call pays a facilitator fee. Part of it is swapped for $HUSH and sent to the incinerator. Share: TBD at launch.
Holder tiers
Your $HUSH balance is read live. Higher tier: lower fees, more shop slots, priority routing.
[05] MCP native
Claude can shop now.
Plug the HUSH MCP server into Claude, Cursor or any MCP agent. It browses the shop and pays per call, inside its leash.

}[06] Composite calls
One call, every seller paid.
A composite call pays every upstream seller in the same transaction, each on its own one-time address.
[07] Per-call escrow
Pay only for answers.
Money waits on the one-time address. Valid answer: it settles. Seller fails: it goes straight back.
- ✓ Paid to a one-time escrow address
- ✓ Seller returns a valid answer
- ↺ Or the gate refunds the payer, same minute
[08] Hush Gate
Any endpoint, paid and private.
One middleware. Price an API, a model or an agent in SOL or USDC. Paid calls land on fresh addresses only you control.
import { hushGate } from "@hush/gate";
export const GET = hushGate(
{ resource: "/forecast", price: "0.001",
currency: "SOL", secret, rpcUrl, network },
async () => Response.json(await forecast()),
);[09] Leash
Humans hold the leash.
Every agent gets its own wallet, funded from Phantom. Limits are checked server-side before a single lamport moves.
Leash
Daily budget
Cap what an agent spends per day. Resets at midnight UTC.
Leash
Per-call cap
No single call above your limit, checked against the seller's real 402.
