Yuno Wallet documentation

Connect an AI agent, review authorizations, and test the temporary mock-card flow.

Yuno Wallet gives you one place to connect an AI agent, add a payment method, and approve the exact authorization it requests. Temporary-card issuance is mocked: Wallet evaluates an intent and can return a synthetic, non-chargeable credential without handling a purchase.

What you can do today

Use the public MCP endpoint from a compatible client, sign in to your Wallet account, and let the client request an authorization for a proposed purchase. You review the merchant, amount, scope, and expiry through a unique approval link.

Current scope

Two rails: mock by default, Visa when you ask for it

Wallet creates and approves authorizations, evaluates proposed purchase intents, and issues purchase-bound temporary mock cards. An authorization created with mode: "network" runs on Visa Intelligent Commerce instead: after you approve it, you confirm the purchase instruction with a Visa Payment Passkey and Visa issues a real network credential against your enrolled card token.

Mock authorizations never contact a merchant, processor, or payment network. Network authorizations reach Visa, which enforces the instruction limits itself. See Visa Intelligent Commerce for the whole flow.
