Military-Grade Security

Every component independently audited. Real cryptography, not placeholders.

Real BouncyCastle Crypto

Every message is protected with production-grade X25519 Elliptic-Curve Diffie-Hellman key exchange and AES-256-GCM authenticated encryption — the same algorithms used by Signal and WhatsApp.

Keys are derived using HKDF with unique ephemeral keypairs per message, providing perfect forward secrecy. Your private keys never leave your device.

Encrypted Local Storage

All chat messages, contacts, and settings are stored in a SQLCipher-encrypted database on your device. Even if someone physically accesses your phone, they can't read your messages without your wallet key.

Combined with wallet-signed authentication (no passwords — your wallet IS your login), rate limiting (10 msg/sec), and 256KB payload caps, the entire system is hardened against real-world attacks.

Why Native Protocol?

We rebuilt MumbleChat from scratch — no XMTP, no third-party dependencies. 100% native messaging on Ramestta blockchain.

🔐

X25519 Encryption

Production-grade BouncyCastle X25519 ECDH key exchange and AES-256-GCM. Real crypto, not simplified placeholders. Keys never leave your device.

⛓️

On-Chain Identity

Your wallet address IS your identity. Public keys stored on MumbleChatRegistry smart contract. No emails. No phone numbers. Self-sovereign and censorship-resistant.

🌐

P2P Relay Network

Managed hub for NAT traversal with multi-node relay support. Messages are end-to-end encrypted — relay nodes see only opaque blobs. Queue caps protect against memory attacks.

💰

MCT Tokenomics

Sustainable reward model with halving every 100K MCT minted. 0.1% transfer fee goes to relay node pool. On-chain verified relay proofs prevent fraud.

📱

Native Android

Built directly into RamaPay wallet with Kotlin/Jetpack Compose. No WebView hacks. True native performance with SQLCipher encrypted storage and background relay service.

🛡️

Hardened Security

Wallet signature authentication prevents Sybil attacks. 10 msg/sec rate limiting. 256KB payload caps. 200 msg/user queue limits. Production logging only.
