Generate hosted USDC checkout pages, detect payments on-chain, and fire webhooks to your app — all without touching your customers' funds.
Three steps. No KYC, no custody, no conversion to fiat.
Set your USDC amount, add a title and optional expiry. We generate a unique hosted checkout page with a QR code.
Your customer scans the QR or copies your Stellar address. Funds go straight into your wallet — we never touch them.
We watch the Stellar ledger and fire a signed webhook to your server the moment payment confirms.
Shareable /pay/* links with QR codes, live status, and receipt screen.
HMAC-SHA256 signed events: invoice.paid, invoice.partially_paid, and more.
Payments go direct to your Stellar address. We never hold or move your funds.
Unique memos per invoice so you can identify which invoice was paid even with a shared address.
Smart detection of partial pays, overpayments, and late payments after expiry.
Exponential backoff with up to 5 retry attempts. Delivery logs included.
No transaction fees. No percentage cuts. Flat subscription.
Never. All payments go directly to your Stellar wallet address. PayLinkr only watches the blockchain — we have no access to your funds.
Stellar network, USDC (Circle). XLM is also detectable. We plan to expand to more assets and networks over time.
We sign every webhook with HMAC-SHA256 using your secret key. Check the X-PayLinkr-Signature header. See our developer docs for example code.
We still detect it and mark the invoice 'Late Payment', fire a webhook, and show a receipt. No payment is ever silently ignored.
