NEX is a novel trustless NFT-to-NFT exchange, here two people can exchange their NFTs with ease.
This application makes life easy just like old days when we used to exchange pokemon cards. Exchanging NFT to another NFT is a huge problem now. There are currently only two options but both have thier own downsides. List in a marketplace: There is a hugh possibility that someone else could buy it or the intended person may not have enough crypto to make this happen. Blind-Trust: Sending the NFT to other person, trusting that he/she will pay you back. (Stupid option xD). So this application solves this problem.
How it's made
So i have used chainlink vrf to create unique random hash so that you can share it with your friend for swapping NFTs and nobody else can spam. And I have deployed smartcontracts in polygon testnet. Also used moralis for frontend to blockchain connectivity. Build a smart contract which will act as a mediator so people don't have to trust eachother.
