Your AI asks. You decide.

A simple wallet for the AI age. Your assistant can request a payment — nothing leaves until you approve it.

Nothing leaves until you approve it.

Simulation. Nothing is sent.

What happens when your assistant asks for money.

Five steps. Only one of them can say yes, and that is you.

  1. MCP

    Your assistant asks

    It can see your balance and ask for a payment. It has no key, so it can't pay on its own.

  2. Policy

    Your rules check it

    We check the request against the limits you set: how much per payment, per day and per month, and who can be paid.

  3. Passkey

    You decide

    Your phone shows exactly what will be paid, to whom and where. Hold to approve with Face ID, Touch ID or your PIN.

  4. Secure enclave

    Your key signs

    Your key lives in a sealed hardware vault. It signs only what you approved, or what your own limits allow. We never hold it.

  5. On chain

    The payment goes out

    It settles on Solana, Ethereum, Base or Cardano. You see it in your activity.

Try to hack it.

Built from parts you can check.

Passkeys
Sign in and approve with Face ID, Touch ID or your device PIN. No password. No seed phrase on screen.
Turnkey secure enclaves
Keys are generated and used inside hardware-isolated enclaves. ZyroPay never holds them and cannot move your money.
Server-side policy engine
Dollar limits per payment, day and month, recipient allowlists and expiry, checked before your phone ever buzzes.
Model Context Protocol
Any assistant that speaks MCP can connect with OAuth, read balances and ask for a payment. You can revoke it at any time.

Proof, not promises.

Three things the app shows you, so you don't have to take our word for it. Examples below.

What you saw is what gets signed

Every approval is bound to the hash of the exact transaction you reviewed. A signature over anything else is refused.
