Introduction

The Open Hack is a hybrid hackathon created to empower developers across India to build consumer-facing applications on TON — real-world products that everyday users can interact with and enjoy.

Over a period of one month, participants will progress from idea to prototype to TON integration through a structured program combining expert mentorship, technical workshops, and continuous builder support. The journey concludes with a live finale at our side event during India Blockchain Week 2025 in Bangalore, where the top ten teams will present their projects to industry partners, investors, and the TON ecosystem.

Unlike traditional hackathons focused on infrastructure or tools, The Open Hack encourages developers to create user-first applications — marketplaces, games, social utilities, learning platforms, and more — designed to make blockchain technology accessible and useful in daily life.
