There whould be several options here within buying, bidding or selling an NFT. In time we would also like a monitoring function for projects.

It will need to be able to run without interaction so will required to use custom mnemonic as per the opensea example here: [login to view URL]

Initially it will be only for Ethereum ERC721 Tokens, but then the addition of Matic (Polygon) / Sol (Solana) may come later as well.

This could be a longterm project in which we will keep updating and making the product better with the developer that is chosen.
