This is a bot for the XRP Ledger, known as the XRPL, that automates buying and reselling NFTs. It is written in Python and works by watching the market for NFTs listed below a price ceiling you set, buying them right away, then relisting them for sale at a higher floor price you also choose. When it relists a bought NFT, it works out the original creator's royalty and any marketplace fee automatically, so the resale price is set high enough that you still make your target profit after those costs are subtracted. There is also a mode that caps how much NFT inventory the bot holds and moves any extra XRP profit into a separate cold wallet, which is a wallet kept offline for safekeeping. You can also give the bot a list of specific NFTs to snap up the moment they appear for sale, and a separate protected list of NFTs it should never sell or make offers against. The bot can place standing low offers across an entire NFT collection at once, tracking which pieces change owners and cleaning up old offers automatically. Before risking real funds, there is a dry run mode that lets the bot go through its full buying and selling logic in simulation, logging what it would have done without spending any XRP or submitting real transactions. Under the hood, the bot keeps a persistent connection open to an XRPL server rather than reconnecting for every request, and it uses a ledger feature called Tickets so buying and relisting can happen at the same time without conflicting. It automatically tops up its supply of these tickets when they run low. It also checks transaction fees on the network each cycle so it can adjust its own fees during busy periods. To run it, you need Python 3.11 or newer and a funded XRPL wallet, since the ledger requires a small amount of XRP reserved for each active offer and for storing NFTs.
