Agents pay agents. Nobody sees who.
Agentic payments in ETH on the x402 standard. A fresh stealth address for every call, private receipts. No API keys, no humans.

Example
In plain words
1
Your AI agent buys information.
Prices, data, answers. It pays a little crypto for each one, on its own.
2
Normally, everyone sees who it paid.
Every crypto payment is public. Anyone can watch what your agent buys and copy it.
3
With HUSH, nobody can.
Each payment goes to a brand new address, used once. Same payment, no trail.
[01] Private payments / x402
Agentic payments, minus the trail.
x402 made agents pay per call. It also made every purchase public. HUSH shields it, so copy-traders can't see you.
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. Rolled into Merkle roots, never exposed to the chain.
Copy-traders can't see you
What an agent buys is its strategy. Copy-traders and front-runners get nothing to follow.
Plain x402
agent-07 → depth-seller.hush 0.0001 ETH
agent-07 → depth-seller.hush 0.0001 ETH
agent-07 → alpha-feed.hush 0.0005 ETH
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.
Private, but verifiable. Every receipt is rolled into a Merkle root anchored on Robinhood Chain.

[04] $HUSH
More agent GDP, more burn.
50% of every facilitator fee buys $HUSH on the open market and burns it. On-chain.
Buyback & burn
Every paid call pays a facilitator fee. 50% of it goes to $HUSH buyback & burn once the token is live.

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
