Ad network · Telegram mini-apps
An ad network for Telegram mini-apps: users watch ads to earn bonuses, advertisers run campaigns, publishers place banners. Over 400,000 users interacted with ads in the first two weeks.

01 / The story
Exto is an ad network designed for Telegram mini-apps. When users interact with these mini-apps, they watch ads to earn bonuses. Advertisers use the platform to create and manage ad campaigns, ensuring efficient ad delivery across the mini-app network while providing a seamless user experience.
Exto needed an advertising network inside Telegram mini-apps where users watch ads in exchange for bonuses. It had to stay non-intrusive for users, give advertisers intuitive and robust campaign tools, and scale reliably with a fast-growing user base.
Exto launched as an intuitive, scalable ad network inside Telegram mini-apps: a hassle-free bonus flow for users, a powerful campaign tool for advertisers, crypto-wallet funding on reliable infrastructure. In the first two weeks, over 400,000 users interacted with ads on the platform.
