Telegram bot for conducting transactions between users

This was a guarantee bot where its essence is as follows: There are two users, one who wants to sell something and the other who wants to buy, and to avoid deception, they conduct their transaction through this bot. It works in such a way that there is an administration that manages finances and assists in transactions. Users find each other using a code generated by the bot, meaning they press start transaction and the buyer gives a code which the seller enters. After that, they transfer either a channel, account, or money to the bot's accounts. When the buyer and seller have pressed everything, the bot checks everything; if all is well, the bot delivers the product to the buyer while the money goes to the seller's balance. The seller submits a withdrawal request, and this request goes to the admin, after which he processes everything.
