Private chat,
sealed on Solana.
✓ Proof of Encryption
WhatsApp, Messenger and Telegram say “end-to-end encrypted”. You just have to trust them. Sealio proves it — every message lives on Solana as ciphertext, and anyone can check it.
Sealio is an end-to-end encrypted messenger where your wallet is your identity. No phone number. No servers reading your messages. Just you, your friends, and the occasional SOL tip for a bad joke.

Proof of Encryption
Messages are encrypted on your device and written to Solana as ciphertext. Open any transaction on Solscan: you’ll see it exists, and that nobody can read it. Only the recipient holds the key.
On-chain delivery
Encrypted messages travel over Solana. No central inbox to hack, subpoena or switch off.
Non-custodial
Your keys stay on your phone. Back them up, take them anywhere. We never hold your funds.
Send SOL in chat
Tip a friend, split a pizza, settle a bet — right inside the conversation.
GIFs & images
Because some arguments can only be won with a GIF.
No phone number
Your wallet is your identity. Add contacts by address or QR code.
Real conversations. Really sealed.
