The biggest crypto bot on Telegram (1.5M+ monthly users): a custodial wallet to buy, sell, store, send and pay with cryptocurrency directly in chat, plus a P2P exchange. Free to use, fees apply on trades.
Full app-like interfaces that open inside Telegram itself — a real UI with buttons and screens, not just chat messages.
A Telegram Mini App is a genuine app interface — buttons, screens, forms — that opens inside a chat window instead of a separate download. Tap the bot's menu button (or a message button) and it expands into a full-screen or half-screen web view, with none of the back-and-forth of a command-based bot.
This is still a small category: most Telegram bots are chat-only, and only a handful of the ones we tested actually ship a proper Mini App rather than a menu that just says so. Here are the ones that do it well — a crypto wallet, a chess board, a QR scanner using your camera, and a couple of task managers.
