About the Hackathon
# 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.

# 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)
