Business

Merchant checkout SDK

Accept private payments on your site without building any zero-knowledge plumbing.

Status: pre-launch. Noirpay is being built. This page describes the design as specified in the whitepaper; nothing on it is live on Robinhood Chain yet, and details can change before launch. See What's live today.

What it does

The checkout SDK renders a payment step that asks the customer's Noirpay account to pay a fresh stealth address for the order amount. The payment shields itself into your merchant vault on arrival, and your server gets an invoice.paid webhook.

What the customer sees

A Noirpay payment sheet with the merchant name, amount and an approve button, inside their app or wallet. No wallet address is shown to either side.

What the chain sees

A transfer inside the pool. Not the merchant, not the customer, not the amount.

What you need

• A business account with a merchant vault.
• An API key with the checkout scope.
• The SDK in your web or mobile checkout.

Integration details ship with the first SDK release.
