Unified Messaging

Every platform. One encrypted inbox.

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

Reply from Vaultr. They never switch apps.

Vaultr encrypted chat with an in-conversation payment

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

A subpoena yields ciphertext.

Signal protocol (1:1)

Prekey bundles and the double-ratchet model secure every direct message with forward secrecy.

MLS for groups

Message Layer Security — the modern standard for scalable, efficient group end-to-end encryption.

Encrypted on device

Messages are sealed before they leave your phone. Vaultr’s servers relay data they cannot read.

In-chat payments

Send money inside a message.

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.

Sending a crypto payment inside a Vaultr conversation

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

Questions, answered

Is Vaultr messaging end-to-end encrypted?

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.

Can I message people on other apps?

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.

How do in-chat payments work?

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.

How does Vaultr stop spam?

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.

Who controls the network?

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.
