Every time you send a "Memo" or a trade intent on-chain, it’s public. If you’re negotiating a large OTC (Over-The-Counter) trade, bots can front-run you. If you’re just chatting wallet-to-wallet, the whole world can read your business. I’m building ShadowDEX to fix this. What is ShadowDEX? ShadowDEX is a decentralized messaging and atomic swap protocol. It treats the Solana blockchain as an immutable, encrypted post office. The core innovation is the Asymmetric Handshake Protocol (AHP) . Instead of using centralized servers or shared passwords, it uses the same math that powers Monero and Signal: Diffie-Hellman Key Exchange (X25519). How the "Secret Handshake" Works: The Ephemeral Key: When you send a message, the client generates a one-time "ghost" key. The Math: It combines your private key with the receiver's public key to create a S
