REFUNDS

A refund button that works.

Customers open a refund flow from their receipt. The assistant asks follow-ups, checks your policy, and routes clear cases — inside your guardrails.

Sorry about that. What exactly is broken or not working? Please add a screenshot that shows it.

Thanks. A feature that doesn’t work is covered by Your business's refund policy, and this is within what I can approve. Approved: 24.00 USDC goes back to you as ETH.
APPROVEDApprove: clear, small casesThe assistant approves within your guard threshold and auto-approve limit. AI approvals still wait out your veto window before the refund executes.

BUSINESS PROTECTIONS

The AI proposes. Your rules decide.

Guardrails apply to every refund — on chain, not just in the assistant. Adjust the controls to see how a $24 request is handled.

FOR YOUR CUSTOMERS

No NEAR wallet. No gas.

Customers manage their receipt, and ask for refunds, without ever setting up NEAR.

Receipt key in the browser

Customers get a private key for their receipt on the device they paid from.

Sign actions locally

Refund requests are signed in the browser. Secrets never leave the customer.

No gas for customers

Zap relays the signed action and covers NEAR gas. No wallet setup required.
