Null Checkout

Create a reusable payment page, track separate customer orders and export verified receipts.

5 min readCurrent exchange release

One public page, separate payment orders

Checkout is a reusable page for project payments, services or community support. Choose the asset and network you want to receive, enter a receiving wallet and add a name and description. Each payer starts their own Receive request, so multiple customers can use the same public link.

The destination and receiving asset cannot be edited after creation. Create another page if either changes. The recipient does not need to connect or sign with the receiving wallet.

Create your checkout ↗

Share the public link, keep the management key private

The dashboard provides a public link, a QR code and HTML for a website button. The button opens checkout on Null Cash; it does not embed a wallet or execute a payment on your website. The QR contains the page URL, not a deposit address.

The server stores a hash of the key. The key is sent in a request header, never in the public URL. Losing the key does not change the receiving wallet or stop payments to it, but it prevents management of this page.

What a customer does

  1. Open the page and check its name, asset, network and destination. Creator identity is not verified by Null Cash.
  2. Select Choose how to pay. A separate seven-day payment request is created for this browser session.
  3. Choose an available sending asset, review the route and fees, and follow the funding instructions on that order.
  4. Save the order and track the final receiving transaction. Do not send funds to the page QR.

Repeated clicks and retries reuse the same session. Returning to the checkout offers Continue your payment. After a completed, returned or expired session, Start a separate payment deliberately creates a new one. Do not use a new browser to retry a payment already funded.

An optional suggested amount is a reference, not an enforced price or guaranteed payout. This release is not a shopping-cart integration, automatic subscription or invoice reconciliation system. Confirm the actual received amount before fulfilling goods or services.

Read verified receipts, not promises

The dashboard refreshes saved activity every 20 seconds while open. Background refresh checks up to three outstanding orders per visit, using the same on-chain delivery verification as Receive. Provider or network delays can leave old snapshots visible; Last verified shows when an order was actually checked.

MetricMeaning
Verified receivedSum of final amounts for verified delivered requests, in this page’s receiving asset.
Delivered paymentsRequests with verified final delivery. Provider completion or intermediate ETH alone does not count.
Orders in progressReserved or ongoing orders, including ones that need attention.
Sessions startedAll requests created from the page, including unpaid and expired requests. This is not a unique-customer count.

CSV exports all sessions with UTC timestamps, status, verified amount, destination and transaction link. Returned or incomplete orders are not included in received totals. A page currently accepts up to 2,000 sessions; create another page after reaching this limit. The dashboard shows 50 rows per page.

Pause new sessions without stranding existing orders

Pause prevents the creation of new payment requests. Existing sessions can still be resumed, funded or completed. It does not cancel orders, reverse transactions or refund money. Resume enables new sessions again. There is no page fee on top of the existing exchange fees; the payer sees route-specific charges before funding.

Checkout inherits current exchange availability, limits, service-fee eligibility, provider processing and automatic final-token delivery rules. It does not guarantee anonymity, instant settlement or delivery on every asset pair. The public page reveals its configured receiving address and asset; other customers’ orders and aggregate revenue remain available only in the management dashboard.
