Cents

Why unique cents

Why the extra cents are the receipt.

A payment ID does not have to be an account. If the amount is unique, the chain already tells you who paid.

How to send one

  1. Open the free invoice tool.
  2. Paste a receive address you control (USDT TRC-20, ERC-20, or BTC).
  3. Enter the dollars. The page adds unique cents.
  4. Send that exact amount. Watch a public explorer for the exact amount.

Why unique cents

Ten people sending 50.00 USDT look the same on-chain. 50.17, 50.42, and 50.08 do not. The extra cents are the payment ID.

Default rail

USDT TRC-20. ERC-20 USDT/USDC and BTC also match if the amount is exact. Ethereum gas can cost more than a small invoice.
