CryptoNotary

I’m Anatolii, the maker of CryptoNotary. To be honest, I am not a professional developer. I come from a creative background, and I was tired of seeing designers and artists get their work stolen or used without payment. Lawyers are expensive, and existing blockchain tools are often too complex for non-tech people. So, I set myself a challenge: could I build a solution over the weekend using AI as my mentor? The result is CryptoNotary. It is a simple, decentralized tool that acts as a "digital witness." It allows you to prove you possessed a specific file at a specific time. How it works (The Magic): Drag & Drop: We calculate the SHA-256 fingerprint of your file locally in your browser. Your file never gets uploaded to any server. It stays 100% private. Sign: You verify the hash using your crypto wallet (MetaMask, etc.). Get Proof: The app generates a professional PDF Certificate of Ownership containing the cryptographic proofs. Why use it? It's Free: We use off-chain signatures (EIP-712), so you don't need to pay any Gas fees. It's Instant: Takes about 10 seconds. It's Beautiful: We spent a lot of time making sure the Certificate looks professional enough to show a client (or a judge). This is my first Web3 project, and I’m super excited to share it with you. Since I built this with the help of AI, I’m sure there is room for improvement! I would love your feedback: Does the flow feel simple enough for non-crypto users? What do you think of the Certificate design? Thanks for checking it out!
