Event-Driven Automation Meets Hyperliquid’s Lightning-Fast L1

TL;DR

Reactive Smart Contracts (RSCs) are compatible with HyperEVM as both origin and destination chain.
Builders gain low-latency triggers, cross-chain execution and a universal $REACT gas model.
HyperEVM brings deep liquidity, dual-block performance and HyperBFT security.

Why HyperEVM?

HyperEVM is an Ethereum-equivalent execution layer baked directly into the Hyperliquid blockchain. It inherits HyperBFT consensus, uses $HYPE as the native gas token and runs Cancun-era EVM with both base-fee and priority-fee burn for maximal neutrality.

The network’s dual-block architecture—small 2 M-gas blocks for swaps and 30 M-gas blocks for heavy contract calls—keeps routine trades snappy without throttling complex deployments.

Pair that with Hyperliquid’s on-chain order book and zero-gas perpetuals, and you get one of the deepest liquidity venues in crypto and one of the most exciting chains for developers to build.

Institutional-grade tooling is arriving fast across HyperEVM.

What Reactive Network Adds

Cross-chain triggers - RSCs on HyperEVM can react to events on any Reactive-enabled chain—and vice-versa—without off-chain relays.

Universal gas - Pay execution fees in $REACT across every connected network.

GMP Compatability - Permissionless cross-chain messaging via a modular, trust-minimised layer

DeFi & Trading Use-Case Spotlights

Perp Hedging Robot - An RSC listens for large liquidations on Hyperliquid’s order book and auto-opens hedge positions on another futures DEX.
Cross-Chain Delta-Neutral Vault - Price feeds on HyperEVM trigger transfers of collateral to Arbitrum vaults (for example) whenever basis risk exceeds a user-defined threshold.
NFT Floor-Price Defender - If Hyperliquid spot markets slip 5% below OpenSea ETH floors, an RSC sweeps listings on HyperEVM and bridges assets to mainnet.

Developer Quick-Start

About Reactive Network

Reactive Network introduces Reactive Smart Contracts—on-chain programs that react autonomously to events across any blockchain. Powered by Hyperlane and fueled by $REACT, Reactive removes the complexity of bridges, keepers and off-chain crons, letting builders ship truly cross-chain dApps in hours, not weeks.

Reactive Streak System in World of Rogues

World of Rogues is a post-apocalyptic multiplayer RPG that blends on-chain logic with gameplay design. One standout mechanic is a streak system, built entirely on smart contracts. It tracks daily claims and issues rewards in the form of in-game points and NFTs once players reach specific thresholds. The core logic

Reactive Network Integrates Arbitrum

Bringing Event-Driven Automation to the Heart of L2 DeFi & DeFAI Reactive Network is excited to announce native support for Arbitrum One, Ethereum’s flagship Layer-2 roll-up. Starting today, developers can deploy Reactive Smart Contracts (RSCs) on Arbitrum One and link them—permissionlessly—to any other Reactive-enabled chain through Hyperlane’
