without a Treasurer
Money in from many people and spending decided by many. Five chains under one balance, and nobody holding it for everybody.

NOBODY HAS TO HOLD IT FOR EVERYBODY
GROUP WALLET
MESSENGER
A wallet your group runs together, right inside the chat: paying is as simple as sending an emoji. Messages and signatures are encrypted on your own device, so not even the server can read them.
No phone number, no e-mail·End-to-end encrypted on MLS·RFC 9420·The server holds no keys

Multichain Treasury
Private and
Public Groups
A room only its members can read, or one anybody can find and join. Either way the server carries ciphertext, and everybody’s keys change the moment the membership does.
full encryption
Crypto Holdings
Bitcoin, Ethereum, BNB, Tron and Solana with the tokens on them, in one list under one balance — and every coin says which chain it is on.
five chains non-custodial
Daily Messaging
A full replacement rather than a wallet with a chat bolted on: threads and replies, folders, files, voice notes, polls, saved messages, bots.
full encryption
Calls and
Conference Calls
One to one or the whole group, audio or video. The media key is derived from the group’s epoch, so it rotates when the membership does.
full encryption
Your Own
Company Chat
Outside services not an option? One command raises the whole thing on your own machine — same client, same encryption, and your people still reach anybody outside.

Group wallet
The group's money sits in one wallet, but each member's key stays on their own device. A transfer needs enough signatures — three out of five, say — so nobody spends the shared money alone.

Every chain at once
All coins and tokens in one list: Bitcoin, Ethereum, BNB, Tron. One combined balance, and every coin says which chain it is on — USDT on Tron won't be confused with USDT on Ethereum.

TECH INSIDE
Every Device
Is Connected
All your devices talk to one server. It puts messages in order and carries calls — and it cannot read any of it, it only carries.
Anyone Can Run
Their Own
Anyone can run their own server for their own people: a company, a community, one person on a machine at home. That is a federation.
Every Federation,
One Mesh
Federations are linked to each other, and your device only ever talks to its own. Which rooms you are in does not depend on which federation you joined through.
One Member,
One Secret
Every secret is made on your own device and never leaves it — not to the server, not to the other members.
Two Secrets,
One Key
Two devices agree on a shared key without either of them ever sending its secret.
A Room With
Only Their Doors
The group’s key is made from every member’s secret at once. Only the people in the room can read what is said, and when somebody leaves, the way they came in stops working.
Keys In
Different Hands
A group’s wallet has no owner. Every member keeps their own key on their own device, and the money moves only by the rule they agreed on.
Two Of Three,
And It Moves
A payment waits until enough of them have signed — any two of three, any five of nine, whatever the group set. Until then it is only a request.
Four Chains,
One Group
Bitcoin, Ethereum, Tron and Solana each want a signature in a shape of their own. The group signs the same way for all four.

The questions
that come first
What does it cost?› Who holds a group’s money?› Can the server read my messages?› What if I lose my phone?›
All sixteen answers ↗MLS · RFC 9420any 2 of 3epoch 4
- Only the network feeMoving money costs what the chain charges to move it. None of that comes here.
- No accountNo phone number, no e-mail, nothing to confirm. You install it and you are in.
- Twenty-four wordsLose the phone and the money is still yours — the phrase restores every address on every chain.
- Your own machineRun the federation yourself and what you pay for is the box it runs on.
