Quick answer

A Telegram Mini App is a web application that runs inside Telegram, launched from a bot, a link, a button or the attachment menu, without installing anything. It can use the user’s Telegram identity, theme, payments in Stars and TON wallets. Popular Mini Apps include games, tap-to-earn apps, shops, wallets, booking tools and quizzes. Developers love them because distribution happens inside chats — and they earn from ads through networks like Adsun, which provides Reward, Interstitial and Task blocks with USDT payouts.

Many add Stars purchases too: paying users buy items, everyone else watches rewarded ads.

Worked example

Hypothetical example — not real Telegram or Adsun data

A new Mini App reaches 5,000 daily active users. Each user sees 3 rewarded ads a day = 15,000 impressions. At a $1.20 eCPM: 15,000 ÷ 1,000 × $1.20 = $18 per day, about $540 a month. The owner spends $100 on an Adsun CPC campaign at $0.05 per click = 2,000 clicks; 40% open the app = 800 new users, cost per user = $0.125. Replace every figure with your own data.

Adsun measurement methodology

Adsun counts an impression when an ad is rendered in a publisher block, a click when the user opens the ad destination, and a reward only after the server-to-server Reward URL confirms completion. Debug-mode traffic is excluded from billing and reports. Metrics are shown per platform, block and country in the partner and advertiser dashboards. Adsun does not publish aggregate network benchmarks in this guide; any number below marked “Hypothetical” is illustrative only. See the SDK documentation for integration details.
