Unified Messaging
Your conversations shouldn’t live on someone else’s server. Vaultr is built on Matrix, encrypted end-to-end by default, and bridges every app you already use into one private inbox.
The unified inbox
Through Matrix’s bridge architecture, Vaultr becomes your universal inbox. You get privacy and consolidation without asking a single contact to change their habits.
Encryption by default
Prekey bundles and the double-ratchet model secure every direct message with forward secrecy.
Message Layer Security — the modern standard for scalable, efficient group end-to-end encryption.
Messages are sealed before they leave your phone. Vaultr’s servers relay data they cannot read.
In-chat payments
In Vaultr, value is a message type. Request an amount on any chain; it appears in the thread, claimable with a code, protected by on-chain escrow with the fee shown before a cent moves.
No copying addresses between apps. No guessing networks. As natural as attaching a photo.
Anti-spam
Unknown senders must post a deposit before reaching you. Scammers pay to spam; the honest get it back. Market design beats any algorithm — and it never makes a wrong judgment call about your conversations.

FAQ
Yes, by default on every conversation — not as a setting you toggle. One-to-one chats use the Signal protocol’s prekey model; group chats use MLS (Message Layer Security). Messages are encrypted on your device, and Vaultr’s servers only ever relay ciphertext.
Yes. Vaultr is built on Matrix and bridges to Telegram, WhatsApp, and Signal, plus native XMTP for Web3. You reply from Vaultr and it reaches your contact on their platform — they never need to install anything.
Create a payment request inside a thread — amount, token, and chain. It appears as a message with a claim code. The recipient claims it, the on-chain escrow fee is shown transparently before funds move, and the whole flow stays inside the conversation.
With economics, not moderation. Unknown senders must post an anti-spam deposit (in BMZ) before their message reaches you. Scammers pay to spam; legitimate senders get the deposit back when you engage. Tiered rate limits further throttle cold outreach.
No one. Matrix is an open, federated protocol — like email for messaging. It can’t be shut down by a single company’s decision, and Vaultr relays only encrypted data it cannot read.
Your vault. Your keys. Your messages. Your money. Your identity. Your rules. Get it on every platform — and if they’ve blocked the stores where you live, install the PWA and walk right in.
