As a first round, you are tasked to complete a short technical find below the steps to follow: 1) Create an ERC721 contract, which can allow users to mint 1 NFT at a given time, provided they pay a minimum price of 0.01 in ETH. 2) Create a second ERC721 contract, which can allow users to mint an NFT, provided then transfer the NFT from the first contract above to the second contract (which escrows the token). 3) At a later stage, the user can swap back the second NFT back for the first that price is zero for the swap functionality. 4) Finally, deploy all contracts following best practices of Solidity, keeping upgradability and reusability in mind.

    Hello I’m looking for someone who can assist me in developing a program or already has a working program that meets my requirement . Please be specific in your reply if you want to be considered. I am after a program that scans recent opensea sales, determines which wallets have accepted offers/bids below the collection floor price. Program will then bid on all their NFTs based on certain criteria below the floor price. The program needs to auto outbid any offers as well till sold , time period passes or becomes unprofitable. If the bids are accepted the program will automatically relist the NFTs for sale. Once the NFT is sold the program will convert the ETH back to WETH The program should run in autopilot once it’s been set up
