The messenger
they can't crack.

End-to-end encrypted with post-quantum cryptography. Keys verified on the blockchain. Sender sealed. No tracking. No compromise.

1 Keys exchanged on-chain

Your public keys are anchored in a Sparse Merkle Tree, committed to Base L2. The shared secret is derived without ever transmitting a private key.

2 Every message, a new key

The Double Ratchet rotates encryption keys per message. Compromise one — the rest stay sealed. That's perfect forward secrecy.

3 Even we can't see the sender

Sealed Sender hides who sent a message — our relay can't tie messages to your identity. By design.

Sealed Sender

Not even our server knows who sent a message.

Sender Sealed

Double Ratchet

A new encryption key per message. Perfect forward secrecy.

Forward Secrecy

Blockchain Key Transparency

Keys anchored on Base L2. Sparse Merkle Tree. Forged keys are caught instantly.

Kill Switch

One tap. Everything gone. Blockchain-triggered remote wipe.

Auto-Destruct

30 seconds to 7 days. Messages vanish on a timer, or via Dead Man's Switch.

One app

Everything, in one encrypted place.

Direct messages, group chats, Stories and disappearing media — all end-to-end encrypted, all under keys that only you control.

Share keys without
trusting anyone.

PHANTOM anchors every public key on Base L2. Both sides derive a shared secret over the chain — the private key is never transmitted and lives on no server.

Equivocation detection means a forged or swapped key is mathematically impossible to hide. You verify the cryptography, not us.

Auto-destruct

Messages that vanish on your terms.

Set a timer from 30 seconds to 7 days. Or arm the Dead Man's Switch — if you don't check in, everything wipes itself.
