Lightchain Desktop

Windows

Windows 10 or 11, 64-bit · 117 MB

Run the installer once. It installs for your user, with no administrator rights, and adds Start-menu and desktop shortcuts.

First launch: if Windows says it protected your PC, choose More info then Run anyway.

macOS

macOS on Apple Silicon (M1 and newer) · 138 MB

Open the file and drag Lightchain Chat into Applications. After that it opens from Launchpad or Spotlight like any app.

First launch: if macOS says it cannot open the app, go to System Settings → Privacy & Security and choose Open Anyway.

What's new

What changed in each version. The full notes are on GitHub.

Version 0.1.1LatestOctober 13, 2026

Fixes paid questions, which failed for everyone on 0.1.0. If you are on 0.1.0, please update.

Fixed

  • Questions to models are answered again. In 0.1.0 every paid question failed with "the frame carried no signature" after the fee was taken.
  • For Workers no longer says Docker is missing when it is running. Opened from the Finder or the Dock on a Mac, the app could not find Docker, Ollama or Foundry.
  • A model's reasoning no longer ends up inside its answer.
  • Testnet models can be reached again.

New

  • Formatted answers on the Models page: headings, lists, links, and code blocks with a Copy button.
  • Live status while you wait for an answer, and a folding section for a model's reasoning.
  • A question box that takes several lines: Enter sends, Shift+Enter starts a new line.
  • Resizable panes: drag the edge of the sidebar, the model list or the people panel.

Version 0.1.0October 2, 2026

The first public beta: peer-to-peer rooms, a six-chain wallet, paid AI answers and worker hosting.

Frequently Asked Questions

What the app is, what it runs on, and what to expect the first time you open it.

One app for Lightchain: peer-to-peer chat rooms, a wallet across six chains, paid AI answers from models on the Lightchain network, and the tools to run a worker or validator. It talks to other people directly, with no account and no central server holding your messages.

The app is free and open source. Asking a model is paid in LCAI per answer, at the price shown beside each model. Chat, the wallet and everything else cost nothing beyond normal network fees.

Windows 10 and 11 (64-bit), and Macs with Apple Silicon (M1 and newer). Intel Macs and Linux are not offered as downloads yet.

This beta is not yet code-signed, so Windows and macOS cannot name the publisher. On Windows choose More info, then Run anyway. On macOS open System Settings, Privacy & Security, then Open Anyway. You only need to do this once.

On your computer, encrypted with the password you choose. When you create the wallet the app shows a twelve-word recovery phrase once - write it down, because it is the only way to restore the wallet and nobody can recover it for you.

Not to chat or hold a wallet. To ask a model you need LCAI in the wallet, then a small top-up of your AI credit from the Account page - the app walks you through it.

Yes, on a machine with Docker, Ollama and a suitable GPU. The For Workers page checks your machine, the models it can serve and your stake before anything starts, and the worker keeps running in the background when the app is closed.

Lightchain Desktop is in beta, so tell us on Discord (discord.gg/lightchain): what you were doing, what you expected and what happened. The app can export a diagnostics file from Settings that helps us find the cause - it never contains your keys, recovery phrase or messages.

Download the newest version from this page and install it over the old one. Your wallet, rooms and settings stay where they are.
