Crypto Autobuy Bot

A self-serve store bot with its own credit wallet. Users top up with crypto, buy from a button panel, and get their product delivered instantly in DMs - with no human in the loop.

A store that runs itself

This is a store with no one behind the counter. Everything happens on its own, inside Discord.

Each user has a credit wallet. They buy from a simple button-and-dropdown panel, pick a quantity, add a coupon if they have one, and confirm. The bot slices the items out of the stock, delivers them to their DMs as a file, and saves everything to its own database. It even auto-holds products when they expire and warns buyers before time runs out.

Crypto in, product out

To add credits, a user runs a command and the bot creates a live crypto invoice through a payment gateway. They pay, and that is it.

When the payment lands, the gateway calls back to my Flask server. The bot checks the signature with HMAC first, so nobody can fake a payment, then credits the user and logs it. A custom, auto-recovering lock keeps the file database safe even under many buyers at once. It is about 2,400 lines, and once it is running, it sells and delivers while I sleep.
