# Introduction Welcome to **Somnia Reactivity Mini Hackathon**, a global, online event taking place from **Feb 25th to March 20th, 2025.** The Somnia Reactivity Mini Hackathon invites developers and builders to explore Somnia Native On-chain Reactivity and build the first generation of truly reactive dApps on blockchain. Reactivity isn't just an incremental improvement,it's a paradigm shift that enables real-time,trustless and decentralised reactions without relying on external systems. This hackathon is a chance to experiment, prototype, and showcase potential use cases of this breakthrough technology to the Web3 developer ecosystem. Join our [Telgram group](https://t.me/+XHq0F0JXMyhmMzM0) for all hackathon related queries and requesting test tokens! You can the detailed documentation [here](https://docs.somnia.network/developer/reactivity). . # Timeline - **Registration Opens:** Now - **Hackathon Kickoff:** Feb 25th, 2026 - **Submission Window:** Feb 25th – March 20th, 2026 # Prizes - 300$ worth SOMI tokens to each winner project. - Social media spotlight for winner projects and mentorship support. - Select projects will be converted into tutorials, case studies, and reference implementations to support future developers. # Track There is one open track. Your project must integrate Somnia Reactivity to build a functional prototype that utilises the SDK  in a meaningful way. # Inspiration & Example Ideas - DeFi: Reactive liquidation engine or dashboard updating in real time - Analytics Dashboards: Real-time visualizations of on-chain events - Onchain Trackers: Onchain referral systems, Whale trackers, Liquidation guardians, etc. - Gaming: Multiplayer on-chain game with instant updates (game logic, session management, live state sync, etc.) - Automation & Infrastructure: [Cron scheduler](https://docs.somnia.network/developer/reactivity/tutorials/cron-subscriptions-via-sdk), alert system, cross-contract orchestrator # Submission Requirements - Public GitHub Repo link with a Read Me file explaining how Reactivity was used. - Working Web3 dApp deployed on Somnia Testnet. - Demo video (2-5 min) # Workshop and Mentorship During the hackathon, the Somnia team and guest mentors will host: - Intro to Somnia Reactivity Workshop - Live Office Hours for debugging and feedback on Discord # Judging criteria - Technical Excellence - Is the project functional, stable, and well-implemented using Reactivity SDK? - Real-Time UX - Does it leverage the real time feature of Reactivity effectively? - Somnia Integration - Is it Deployed on Somnia testnett? - Potential Impact - Does it have potential to evolve into a real product or ecosystem contribution? # Contact us - X Profile :- [https://x.com/SomniaDevs](https://x.com/SomniaDevs) - Telegram community :- [https://t.me/+XHq0F0JXMyhmMzM0](https://t.me/+XHq0F0JXMyhmMzM0) # Documentation and Resources - Official Docs:[ ](https://docs.somnia.network)[https://docs.somnia.network](https://docs.somnia.network) - Reactivity Info:[ ](https://datastreams.somnia.network)[ ](https://docs.somnia.network)[https://docs.somnia.network/developer/reactivity](https://docs.somnia.network/developer/reactivity) # About Somnia Somnia is a high-performance, cost-efficient EVM-compatible Layer 1 blockchain capable of processing over 1,000,000 transactions per second (TPS) with sub-second finality.
