We're pleased to share that we'll be taking part in the Summer of Ethereum with our friends at ETH Panda and joining some of the most important in-person events for the Chinese speaking ETH Community!

Most DeFi still operates in silos but Reactive Network can remove the walls.
Your contracts can now listen to events on Arbitrum, execute logic on Base, and settle collateral on Ethereum, all without custom bridges or trusted intermediaries.
Cross-chain collateral rebalancing, real-time liquidation protection, automated yield routing… all native. This isn’t another bridge. It’s the layer that makes fragmentation obsolete.

Use case Highlights - DeFi That Never Sleeps
DeFi moves fast, prices shift in seconds, positions drift, and opportunities vanish before most contracts even notice.
Reactive Contracts can watch on-chain events in real time and act instantly. No bots, no manual intervention. Here’s a few examples, let us know if you have any others 🧵
Uniswap Hook Incubator 8 Highlights: Arc-Hook
Arc-Hook is a Uniswap v4 hook created by @drips_young that creates private, invite-only liquidity pools for institutions and big traders.
Normal Uniswap pools are completely public, anyone can see who’s trading and copy them. Arc-Hook fixes this by letting only approved (whitelisted) users join, but it keeps their wallet addresses completely hidden using zero-knowledge tech (KZG commitments).
No one can see who’s in the pool or front-run their trades. It runs on Unichain and uses Reactive Network to automatically keep the private whitelist in sync, no manual updates or central servers needed. This makes it much safer and more attractive for serious money to trade on @Uniswap without exposing their strategies or getting sandwiched.
In other words, it's like a hidden, compliant VIP section inside Uniswap v4.
A lot of people think of Reactive Contracts (RCs) as something only for developers but thanks to ReactDEFI anyone can deploy their own RCs with no coding required.
Utilities currently available include @Uniswap stop loss / take profit orders and a range of @Aave liquidation protection features.
Uniswap Hook Incubator 8 Hightlights: TWAMM-X
Reactive recently took part in the 8th iteration of the Uniswap Hook Incubator to challenge some talented developers to see what they could build with the combination of Uniswap V4 Hooks and Reactive Contracts.
Let's take a closer look at some of those projects, starting with TWAMM-X by @jajak5242, a privacy-first Time-Weighted Average Market Maker hook built for Uniswap v4.
Sound complicated? Basically it's a smart Uniswap v4 hook that lets you make big trades without getting front-run or sandwiched by bots.
It hides your entire order using zero-knowledge proofs and encryption, then splits it into small pieces that execute gradually over time (like a safe TWAP). No one can see what you're buying or selling until it's already done.
For liquidity providers, the fees from these big orders aren't paid in random big lumps. Instead, they get turned into a smooth, steady 24-hour yield stream, so you know exactly how much you'll earn every day.
It also connects to Reactive Network so everything happens automatically, with no extra bots or manual work needed, creating safer big trades and predictable profits for LPs!

We collect questions from our community almost every week, pitch them to our team and post the answers here on X.
Two questions per person max please!
Projects with treasuries on multiple chains waste hours every week chasing fees, collecting swaps on Ethereum, trading revenue on Base, protocol income on Arbitrum… then manually swapping, bridging, and distributing.
Traditional fixes? Multisig drudgery or risky off-chain bots.
Reactive Contracts solve it elegantly: One contract listens for fee events across any chain, automatically swaps if needed, bridges, and distributes proceeds directly to the DAO, stakers, or builders, all fully on-chain and autonomous.
Set it once. Revenue flows in the background. No more manual ops!
If you're in the Toronto area you can join us this coming Thursday from 18:30PM for a seminar co-hosted with @dao_toronto, we'll be talking about building the next generation of on-chain automation.
Great chance to connect with other builders, RSVP below 👇
DeFi strategies can move from static to dynamic. Reactive Contracts allow positions to adjust automatically based on market conditions, enabling real-time rebalancing, risk management, and capital efficiency across chains.
Reactive Contract Utility: Cross-Chain Arbitrage
Cross-chain arbitrage is one of the most powerful opportunities in DeFi, but today it relies heavily on off-chain bots, latency-sensitive infrastructure, and fragmented execution. Opportunities are identified off-chain, transactions are submitted across multiple networks, and execution depends on speed, gas, and coordination. This introduces delay, risk, and inefficiency.
Reactive Contracts change this by making arbitrage event-driven and on-chain. Instead of relying on external systems, contracts can listen to events across multiple chains and respond immediately, turning arbitrage into a native capability of the blockchain itself. 🧵
