Raven

Raven uses steganography and cryptography to embed encrypted messages within ordinary text. Users encrypt content locally on their device, with ciphertext stored on Solana. The system operates pairwise with cryptographic keys—no accounts required, no server-side decryption. Built by a solo developer in spare time, Raven includes a relayer and retention sweeper service. All writes are signed by a shared pool wallet, making transaction volume and timing publicly visible.
