Web Exchange
The full trading interface in a browser, on a screen big enough to use it properly — and installable if you want it out of the tab bar.
What it is
The web exchange is Lovely Legends at llx.lflabs.fund. It runs in any modern browser on desktop or mobile, and it is where the chart, the order book, the depth view and your open orders can all be on screen at once.
It is the same account and the same engine as the Telegram Mini App. Sign in with Telegram in one tap, or with an email and password if you would rather not depend on Telegram to reach your account.
How it works
- Sign in
Telegram in one tap through the login widget, or by confirming a code in the bot if your browser blocks third-party widgets. Or set an email and password and sign in with those.
- Trade with everything visible
Chart, order book, depth, the trade tape, the order form and your open orders on one screen, rather than a tab at a time.
- Install it if you want to
It is a progressive web app: install it from your browser and it opens in its own window with no address bar. It caches its own interface, never your balances or prices.
- Switch devices freely
Sign in on another device and everything is where you left it. Sessions are short-lived and can be revoked.
Key benefits
A real trading screen
Candles, depth, the tape and open orders together. On a desktop the layout uses the width instead of stacking.
Installable, offline-tolerant shell
The interface is cached so it opens instantly and survives a bad connection. Balances, orders and prices are deliberately never cached — a stale number shown as a live one is worse than a spinner.
Two ways in
Telegram sign-in, or email and password. Two independent routes to the same account, so losing one does not lock you out.
The same API behind it
Market makers and algorithmic traders use the documented REST and WebSocket API against the same book.

Important notes
Frequently asked questions
Do I need Telegram to use the web exchange?
No. You can set an email and password and sign in with those. Telegram sign-in is one route in, not a requirement.
Is it the same account as the Mini App?
Yes. One account, one set of balances, one order book. The two are doors into the same exchange.
Can I install it like an app?
Yes. It is a progressive web app — install it from your browser and it runs in its own window. There is nothing in an app store to download.
Why does the Telegram login button sometimes not appear?
The Telegram login widget is a third-party iframe and privacy blockers and some browser settings prevent it from rendering. Use “Continue in Telegram”, which does not rely on it.
How long does a session last?
Web sessions are short-lived and can be revoked. Signing out ends the session on that device immediately.
