Core checkout pattern

1. Create a pending order with a unique amount.
2. Buyer sends exact USDT on BNB Smart Chain.
3. Service checks token transfer logs or a pasted tx hash.
4. Confirmations are required before paid status.
5. Paid order unlocks a download token.
6. The same transaction hash cannot pay multiple orders.

Boundaries

The starter does not custody funds, ask for private keys, handle refunds, replace compliance review, or guarantee sales. It is code and documentation for builders who can self-host and audit before production.
