This is a project built for the company I am currently working at. It’s a full-stack web application where users can register and upload their artworks to the Solana blockchain. In this way, for each artwork a certification of authenticity is emitted (much like an NFT).
The user has the option of certifying the artwork without having a wallet: in this case we are the custodial for them. The user can decide in any moment to reclaim custody of the certificate by providing their wallet address.
