FEATURES

Built for the
future of privacy

Every feature designed from the ground up with decentralization and encryption as non-negotiable foundations.

Wallet-Native Identity
Your wallet address is your identity. No phone numbers, no emails, no data to harvest. Generate a new address anytime.
E2E Encryption
AES-256-GCM encryption with forward secrecy. Your messages are unreadable by everyone — including us. Verified on-chain.
Fully Decentralized
No central servers. Messages relay through the Waku protocol. No single point of failure, no censorship, no downtime.
QR Code Sharing
Share your profile instantly with a scannable QR code. Others scan it and start an encrypted chat — zero typing required.
Group Chats
Create encrypted group channels for your DAO, team, or community. Every message is end-to-end encrypted for all members.
Rotating Addresses
Generate new wallet addresses at any time. Your old addresses are preserved in history. Ultimate privacy through identity rotation.

Message with Zero Trust
Send text, files, voice messages, and reactions — all encrypted. Read receipts, typing indicators, and replies work without compromising privacy.
SECURITY

Unbreakable by design

We don't just encrypt your messages. We built an architecture where reading them is mathematically impossible — even for us.

AES-256-GCM Encryption
Military-grade encryption standard. Every single message is individually encrypted with unique session keys.
On-Chain Key Verification
Encryption keys are exchanged and verified on the blockchain. No MITM attacks. Cryptographic proof of identity.
Perfect Forward Secrecy
Session keys rotate automatically. Compromising one key doesn't decrypt past or future messages.
Zero-Knowledge Architecture
We never see your messages, metadata, or contacts. Everything is encrypted client-side before it touches any network.
