Solo dev. built in my spare time.

Raven uses a combination of steganography and cryptography to create a metadata resistant messenger. It encrypts any piece of text on your device and stores the ciphertext on Solana. It works pairwise with keys, users decrypt locally on their device- no accounts. I do run the relayer and a retention sweeper (not claiming peer to peer). One more thing, every write is signed by the same pool wallet, so anyone can see volume/timing. Check the white paper below and there’s been no audit.

Several variations include: public, private, and stealth (for fun, i’ve hidden a public raven in this post)
