We would like to automate some OpenSea activities through the OpenSea SDK (Javascript - [login to view URL]) this would run in a loop checking a MySQL database for entries, which will specify the bid, buy or sell action (Including the contract address, token id and any other relevant information required to make the bid or purchase).

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.
