Description
FlashBack is a Reactive Network hackathon project demonstrating an end-to-end automated flow from risk event to destination-chain execution.
The system uses real testnet contracts and callbacks, calculating protection size from position values instead of fixed demo numbers.
- Implemented the Reactive contract backend and cross-chain callback path.
- Deployed across Ethereum Sepolia, Base Sepolia, and Reactive Lasna.
- Won first prize in the Reactive Network Casual Hackathon.

Cross-chain protection architecture and deployment
Shows the event monitoring, cross-chain callback, and protection path across Ethereum Sepolia, the Reactive contract, and Base Sepolia.
On-chain execution and protection result
After the wallet is connected, an origin-chain risk event triggers a Reactive callback and produces a verifiable protection result on Base Sepolia.
