[ On-Chain If-This-Then-That for Smart Contracts ]
Smart contracts need to react across chains. Today that means off-chain bots, custom infrastructure, and constant maintenance.
Reactive Network replaces all of it with a single on-chain automation layer.
Follow Reactive Network for updates.
Latest News
With Reactive Contracts, applications can:
[+] Subscribe to events on supported EVM chains
[+] Evaluate conditions in Solidity when events occur
[+] Trigger cross-chain transactions automatically
No bots. No off-chain infrastructure.
Just continuous, event-driven automation.
[ More Coming Soon ]
Cross-Chain Reach
Subscribe to events on any supported EVM chain. React from one contract.
Auto-Execution
No callers, no keepers. Reactive Contracts fire when their conditions are met.
Composable Logic
Chain Reactive Contracts together to build multi-step, event-driven workflows.
Built to Scale
Event processing runs inside isolated ReactVM instances. No complex coordination overhead.
Direct Log Access
Reactive Contracts read blockchain events straight from log subscriptions. No oracles. No middleware.
Ready to Build
DeFi, gaming, infrastructure, cross-chain ops. If it's event-driven, it runs on Reactive.

ReacDEFI
Automated DeFi using Reactive Contracts that respond to on-chain events without bots or manual monitoring. Personal contracts track conditions such as Aave health factors or Uniswap V2 price changes and automatically trigger actions like liquidation protection, stop-loss, or take-profit orders.

Reactive Bridge
A cross-chain token portal for staking, withdrawing, and transferring REACT. Users can swap REACT to wrapped REACT on Ethereum or Base, or convert wrapped tokens back to native REACT on Reactive.
