Accept payments with Whitechain Commerce
Add on-chain USDT payments to your store.
Whitechain Commerce gives your store a way to accept USDT payments from customers who use a wallet on Whitechain. The funds go straight to your payout wallet. You can confirm payments in the dashboard, verify transactions on the block explorer, and send full or partial refunds from your wallet.
Choose how to accept payments
| If you want to… | Start here |
|---|---|
| Share a fixed-price checkout in a message or on your site | Payment links. Create and share a link from the dashboard without writing code. |
| Add USDT to your store's existing checkout | Store integration quickstart. Create one session per order, redirect shoppers to hosted checkout, and update your orders with signed webhooks. |
| Keep checkout inside your React storefront | Checkout widget. Embed the wallet and payment flow if you can build with the SDK workspace packages. The SDK is not published to npm. |
