How It Works

Payment in 5 Simple Steps

Fully automated from order creation to fund settlement

1

Merchant Creates Order

Create a payment order via API, specifying amount, currency, and callback URL.

User Completes Payment

The user scans the QR code or copies the address on the checkout page to complete the transfer.

3

On-Chain Transaction Monitoring

BlockSettler monitors on-chain transactions in real time, matching orders with transfer records.

Webhook Async Notification

Once confirmed, a signed Webhook notifies the merchant system to update the order status.
