[ 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
A reactive contract is a standard Solidity contract that listens. Deploy it once, and it can:
[+] Subscribe to events on any supported EVM chain
[+] React to them, evaluating conditions in Solidity
[+] Execute transactions on other chains automatically
Works out of the box with Hardhat, Foundry, Remix, and the rest of the EVM toolchain.
[ More Coming Soon ]
Cross-Chain Reach
Monitor any supported EVM chain and react from a single contract.
Auto-Execution
No callers, no keepers. Contracts execute when their conditions are met.
Composable Logic
Chain reactive contracts to build multi-step workflows.
Fast and Final
~1s blocks with instant finality. Once confirmed, callbacks stay confirmed.
Direct Log Access
Read events straight from log subscriptions. No oracles required.
Ready to Build
DeFi, gaming, infrastructure, cross-chain ops — anything event-driven.

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.
