What if smart contracts didn’t need to be manually triggered?

What if they could observe blockchain events, initiate actions on their own, and run forever - across multiple chains?

That’s the idea behind Reactive Smart Contracts.

Traditional smart contracts are limited. They execute once, live on a single chain, and rely on users to initiate every interaction. They were a powerful innovation - but they weren't built for a multi-chain world.

Cross-Chain Reactive Smart Contracts are different.

They can monitor on-chain conditions in real time, use data from any connected L1 or L2, and make autonomous decisions without relying on oracles, relayers, or bridges. 

They don’t just respond - they react.

They manage their own gas balance using $CWEB, regardless of what chain they are deployed on. And, they execute continuously, block after block, without needing constant user input.

This isn’t just a performance upgrade - it’s a paradigm shift.

Because real-world automation, real cross-chain logic, and truly decentralized applications aren’t possible if your smart contracts need to be hand-fed every time they run.

We built Reactive Smart Contracts to fix that.
