Use Cases

Overview​

The Use Cases section primarily focuses on analyzing scenarios where Reactive Smart Contracts might be a game changer.

The Basic Demo Smart Contract is a basic use case of the Reactive Network with low-latency monitoring of logs emitted by arbitrary contracts on any chain (Sepolia testnet in this case) and enabling calls from the Reactive Network to these arbitrary chain contracts.

The Deploying Reactive Smart Contracts with Remix article is a guide walking you through deploying Reactive Smart Contracts using the Remix Development Environment.

The Uniswap V2 Stop Order Demo is a demo of a simple reactive smart contract that implements a stop order upon a Uniswap V2 liquidity pool. Study its setup and try deploying and testing it yourself.

If you have an idea for another use case, feel free to submit and turn it into a bounty, using our Unicornization or Hackathon program.
