Raven — Hidden Messages

Your secret never touches the post. Raven seals it on a public blockchain — the post is just the signal that one is waiting.

Send encrypted messages that never touch the post you publish. Raven lets you write a normal tweet, post, or comment — and seal a message on-chain that only your recipient can open. To everyone else, it's just a post. Why Raven exists Other encrypted messengers protect the contents of your messages. Anyone watching the network sees you and someone else exchanging encrypted traffic — they just can't read it. Over time, who you talk to, when, and how often becomes a kind of message in itself. Raven hides the conversation itself. You're not sending encrypted traffic to a server everyone can see you sending to. You're posting in public, like everyone else does all day, and the post happens to mean something to one specific person. How it works Compose. Write your public post (a tweet, LinkedIn update, anything) and type your secret message underneath. Send. Raven encrypts the secret end-to-end and stores it on the Solana blockchain. You get back the ordinary-looking text you wrote — that's what you post publicly. Recipient scans. Your recipient sees your post in the wild and clicks the Raven extension. Raven recognizes the carrier text, fetches the encrypted blob, and reveals the message. The encrypted message lives on a public blockchain. Anyone can see the encrypted blob; nobody can read it without your recipient's private key. An ordinary public post is the signal that one is waiting — and nobody has reason to look at it twice. What's inside Compose — write a normal post; your message is sealed on-chain, never in the post. Scan This Page — pressing Ctrl+Shift+R (Cmd+Shift+R on Mac) scans the current tab for hidden ravens. Snip Scan — Ctrl+Shift+S to select a region (works on images and text on any site). Paste Scan — paste any text from anywhere into the extension popup to check it. Auto-tune — opt-in subscription so ravens addressed to you arrive without a manual scan. Send via Flock — optional delivery for ravens to recipients who have Raven open. Key management — generate sharable keys for individual contacts (private) or for broadcasting to a circle (public). Export / import — move your identity between devices via QR code or .raven backup file. Privacy by design All encryption happens on your device using the Web Crypto API and the TweetNaCl library. Your keys live in a passphrase-encrypted vault in browser local storage. They never leave your device unless you explicitly export them. No accounts. No passwords on a Raven server. No analytics. No tracking. No ads. What Raven uses Raven uses Solana the way websites use HTTPS — as plumbing for one specific job. You don't need a wallet. You don't pay gas. You don't need to know what a blockchain is or care that one exists. There's no token. No airdrop. Nothing for sale. Cross-device Raven on Chrome shares one portable identity with the Raven web app at sendraven.ink — export from one, import into another.
