Made an encrypted mutual crush identification mini-app to celebrate the Solana launch! Was super fun writing this one and making it secure. Front-end + API + Onchain Program: https://github.com/jc4p/mutual-match-frame https://mutual-match.kasra.codes/

for the nerds: 1. you sign a tx 2. that hash is used to generate a new ed25519 keypair 3. that public key is sent to my server for matching to FID 4. you select a user, encrypt a message using their public key, send to a unique (per duo) Solana program 5. If the program has 2 entries, it’s a mutual match
