Stripe-like checkout for the Stellar network.
Accept USDC, EURC, and XLM payments in minutes — with 5-second finality and near-zero fees.
Stellar has the best payment rails in crypto — sub-5-second settlement, $0.00001 transaction fees, $83M+ USDC supply, and MoneyGram cash-out at 350K+ locations worldwide. But there's no merchant-facing product layer.
OrbitStream bridges that gap.
A business that wants to accept USDC on Stellar today must build payment detection, confirmation logic, checkout UI, and settlement flows from scratch. OrbitStream gives them a Stripe-like experience: a hosted checkout page, embeddable widget, JS SDK, and webhook system — so any merchant can start accepting Stellar payments in under 10 minutes.

1. Merchant creates checkout session via API or SDK
2. Backend generates unique memo, returns checkout URL
3. Customer visits checkout page — scans QR or connects Freighter wallet
4. Customer signs payment (USDC / XLM / EURC)
5. Payment detector matches incoming payment by memo via Horizon streaming
6. Backend marks session paid, dispatches HMAC-signed webhook
7. Customer sees confirmation screen
import { OrbitStream } from '@orbitstream/sdk';
