The extra cents are the receipt.

A $50 invoice that everyone pays as $50 is anonymous. Ten people send $50. You see ten $50 transfers and you cannot tell which one is which. Add unique cents and each invoice becomes its own amount: $50.17, $50.42, $50.08. The chain is the receipt.

What you do

Paste the receive address you control. We never hold it.
Enter a dollar amount. The page adds unique cents.
Send that exact invoice to your buyer.
Watch a public explorer for that exact value. Match = paid.

Why not a payment processor

Processors need an account, a webhook, and a database of who paid. Unique cents skip that. The amount itself is the ID. No login. No custody. No server that stores buyer emails.

What we sell

The hosted tool on this site makes one invoice for free. The $12.37 kit is a single-file generator plus a matching playbook you can run offline. Unlock after the chain shows exactly 12.37 USDT (claim CENTS-4F91). If that amount is taken, 12.41 with CENTS-8M2Q.

Default rail is USDT TRC-20. Ethereum gas on ERC-20 can exceed the kit price. BTC is an optional frozen sat amount, not 12.37 BTC.
