Message privately, join communities and send digital assets, without giving anyone your phone number. Ledger Chat is the first application built on Humanity Ledger.
Everything below is the real interface, drawn live. Nothing is a feature we do not ship.
Payments and agreements run on the Aztec test network with test tokens. The contracts have not been audited yet.
Ledger Chat
Ledger Chat brings the privacy of a decentralized network to a messenger that feels as simple as the ones you already use.
Every direct message is encrypted on your device before it travels. Only the person you are writing to holds the key to read it.
No phone number, no email and no password. You sign in with your wallet, and your account belongs to you alone.
Messages travel over XMTP, an open messaging network, instead of a database we own. There is far less for anyone to breach, sell or watch.
Ledger Chat in your hand
A conversation with a private invoice, a voice call, a video call and a community, the way they look on your phone. Keep scrolling to watch each one happen.
How it works
Anyone can set up a private identity and start a conversation straight away.
Open Ledger Chat in your browser and connect a wallet. Sending messages is free; we pay the network costs.
Choose a display name. Your encryption keys are generated on your device and never leave it.
Share your address, scan a QR code in person, or search the directory for people and communities.
Message, call, or send digital assets inside the conversation, without switching apps.
The conversation is where people already agree on things. Ledger Chat lets them settle them there too.
Run large groups with free and paid channels, announcements, polls and revocable invite links. Paying a member opens a private chat with them, so the community server never sees it.
Send test USDC, DAI or ETH privately to the person you are talking to, once their Aztec address is verified.
Shielded transfers on the Aztec network keep the amount and the recipient off the public ledger.
Use Ledger Chat on your phone and your computer. Link a new device by scanning a code.
Aztec Network and zk.money
Payments are proven on your own device and sent as private notes, so the amount and the recipient are not published. The network fee is the exception: on Aztec Alpha it is paid publicly from your account.
Proofs made in your browser
The proof for each payment is generated on your device. Your keys and notes stay in this browser's storage and are never sent to our servers.
Verified recipients
Money only goes to an Aztec address the other person signed for. If it cannot be verified, the payment is blocked.
Escrow and streaming agreementsTest network
Lock funds until work is delivered, or pay over time, from inside a conversation. Both sides can see the state on Aztec.
Protection against double spending
Each private note can only be spent once. The Aztec rollup enforces this with nullifiers, without revealing which note was used.
Most messengers are paid for with attention and data. Ledger Chat is built around privacy instead of advertising, and it says plainly where it is still catching up.

Privacy is a right, but people only keep using what is easy. We hid the machinery so you can concentrate on the conversation.
Protect the app on your device with a PIN or your device's biometrics, so a borrowed laptop does not mean an open inbox.
Clear type, generous spacing and nothing competing with your conversations. No gas to calculate and no menus to decode.
Zero knowledge proofs and end to end encryption run underneath an interface that feels like any messenger you already know.
All the everyday features of a modern messenger, without advertising trackers or behavioural profiling.
Ledger Chat runs in any modern browser today. Your conversations follow you to every device you link.
