Made an encrypted mutual crush identification mini-app to celebrate the Solana launch! Was super fun writing this one and making it secure.

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

hahaha maybe let me see what @sdv.eth wants to do and how rabbit hole i go on it first

are you gonna do the auction your time thing again?

it's sooooo fun and deriving the symmetric key was a blast, full code: https://github.com/jc4p/mutual-match-frame/blob/243d9e58218bf6dbf0e1776d6fe62adb399b7938/src/main.js#L855

lol sign my public key 🥺 👉👈
the cryptographer in me is getting a kick out a curve25519 being used for this. awesome app!
