Hosted checkout
Create a checkout session and send the customer to a Payclave-branded payment page with an amount, reference, and expiry.
Hosted stablecoin checkout
Accept stablecoin payments with a checkout built for merchant operations.
Payclave gives merchants a hosted checkout, invoice records, payment verification, and webhook delivery while stablecoins settle to the merchant-controlled settlement wallet. Customers get a focused payment experience, and merchants get a reliable record before fulfillment.
Direct settlement
Payments settle to the configured settlement wallet without a later Payclave payout step.
Verified status
Payclave checks settlement independently before an invoice becomes paid and a fulfillment webhook is delivered.
From order to payment record
A checkout flow with a verifiable outcome.
- 1
Create a checkout session
Your server sends the trusted order amount and reference with a secret API key, or a limited browser integration uses a publishable key.
- 2
Let the customer choose how to pay
The hosted page supports a connected-wallet flow or scan/copy payment instructions for supported networks.
- 3
Verify the settlement
Transaction, recipient, token, chain, amount, expiry, confirmation, and duplicate-use checks determine the payment outcome.
- 4
Fulfill from a signed event
Your backend verifies the Payclave webhook signature, handles the event idempotently, and fulfills the matching order.
A checkout flow instead of manual wallet instructions
A reusable wallet address in an order confirmation leaves the merchant to reconcile amounts, networks, transaction hashes, and late payments by hand. A Payclave checkout session keeps those details attached to a single order and gives the customer one canonical payment URL.
The invoice remains pending while payment is in progress. It moves to a paid, underpaid, overpaid, expired, failed, or cancelled outcome based on evidence recorded for that checkout, not on a browser success screen alone.
A narrow settlement setup with flexible customer payment
Merchants configure a settlement wallet for USDC or USDT on Polygon. Customers can use supported source tokens through wallet checkout or generate one-time Scan or copy instructions for supported deposit networks. The merchant-facing invoice keeps one settlement token and amount.
That separation keeps the customer's payment choice inside checkout without turning Payclave into a custodial wallet or exchange service. Payclave coordinates the experience and verifies the resulting settlement record.
Records for payment operations
Checkout sessions, invoices, payment records, webhook delivery status, and latest attempt details remain available in the merchant dashboard and API. Idempotency keys protect session creation, while signed webhooks let the merchant authenticate status changes.
Test mode is separated from live mode so teams can exercise checkout creation, webhook handling, and fulfillment logic before accepting a live stablecoin payment.
Frequently asked questions
Questions about stablecoin checkout.
What is a stablecoin checkout?
A stablecoin checkout is a customer-facing payment flow that attaches a stablecoin payment to an order or invoice. Payclave adds the hosted page, payment instructions, verification, status records, and webhook delivery needed to operate that flow.
Does Payclave hold customer payments or merchant settlement?
No. Payclave is non-custodial and does not hold customer payments or merchant settlement. It never receives, stores, or has access to private keys. Settlement reaches the wallet configured by the merchant.
Which stablecoins can a merchant receive?
Merchant settlement currently supports USDC or USDT on Polygon. Customer payment options vary by the checkout route and connected wallet.
How should a merchant know when to fulfill?
The merchant backend should verify a signed payment webhook, handle the event idempotently, and confirm the matching invoice status through the API when appropriate. A browser redirect alone is not proof of payment.
