Heads up: Reactive Mainnet goes offline for migration on Wednesday, October 28th, at 12:00 UTC. Why Pause? On October 7th, Lasna testnet completed its migration to the Omni fork. Now it's mainnet's turn: Reactive Mainnet is leaving the legacy Geth and Prysm stack and moving
Reactive Staking Season 9 closes at block 7,196,129 on Wednesday, October 14th, and its one-month pool expires with it. Season 10 picks up on the very next block with a two-week pool that runs until the Omni upgrade goes live on Reactive mainnet on October 28th. It is
Reactive integrates with Robinhood Chain, an Ethereum Layer-2 built for tokenized real-world assets, as both an origin and a destination chain within Reactive Network. Stock Tokens and the DeFi built around them already trade around the clock. With Reactive, the logic that manages them can run around the clock too,
Migration is complete. Lasna is now running on the Omni fork. What's Different The biggest change is that the RVM is gone. Reactive contracts now deploy once, to a single environment, as standard Solidity targeting version 0.8.29, and dual deployment is a thing of the past.
Heads up: Lasna goes offline for migration on Wednesday, October 7th, at 12:00 UTC. Why Pause? Back on May 26th, we announced the launch of a new version of Lasna testnet, running on our new CometBFT-based architecture. Now, in preparation for our mainnet migration, the original Lasna testnet, which
On August 12th, Solana came within four and a half percentage points of losing the ability to finalize blocks, and almost nobody noticed. The network kept producing blocks and processing transactions the entire time, the status page recorded nothing unusual, and for roughly half an hour the margin between business
Reactive Staking Season 8 closes at block 6,816,896 on Sunday, September 13th, and its one-month pool expires with it. Season 9 picks up on the very next block, so stakers can roll straight into the next round with no gap in between. The new round keeps the shape
A wallet that wanted to support five bridges used to integrate five SDKs. Five fee oracles, five sets of error codes, five ideas about what "the transfer went through" means. Multiply that by every wallet and every app, and you get the state of cross-chain UX for most
For as long as Ethereum has existed, sending ETH from one address to another has cost 21,000 gas. It is one of the very few numbers that survived every fork, every roadmap rewrite, and every philosophical argument the ecosystem has had since 2015. Wallets hardcode it. Fee estimators assume
Veritas was the sixth and last of the projects in our look at the UHI9 hookathon, and it puts a reactive contract to a use none of the others needed: keeping a stored number true after the thing it measures has quietly changed. The full project lives on GitHub, though
Season 7 is wrapping up. Our 1-month staking pool expires at block 6,437,662 (Thursday, August 13th), and with it we're opening the door to Season 8. Season 8 repeats Season 7 in structure: a single 1-month pool. We're finalizing the final matters of the
Maestro was the fifth of the six projects in our look at the UHI9 hookathon, and it points a reactive contract at something none of the others touched: the real market price, sitting on a different chain. The full project is open here. Maestro is a Uniswap v4 hook whose
Coinstancy has taken on a practical challenge with Reactive Network: how to keep a portfolio aligned with its intended allocation when market prices are constantly moving. Instead of relying on someone to continuously monitor positions and execute trades, the system responds automatically when a portfolio drifts too far from its
Lambda was the fourth of the six projects in our look at the UHI9 hookathon, and it puts a reactive contract to the use Reactive Network is most literally built for: turning an event on one chain into a transaction on another, with no server in between. The full project,
TrancheShield was the third of the six projects in our look at the UHI9 hookathon, and it takes yet another angle on the same limit: a Uniswap hook only runs when someone trades, but a pool's risk does not sit still between trades. Here is how it deals
Unistrata was the second of the six projects in our look at the UHI9 hookathon, and it draws a different lesson from the same limit: a Uniswap hook only runs when someone trades, but some decisions can’t wait for the next trade. Here is how it handles that. The

EvenFlow was the first of the six projects in our look at the UHI9 hookathon, and the one we singled out as the clearest case of something a Uniswap hook simply can’t do on its own. Here is a closer look at how it gets around that. The full

Plenty of teams came through the UHI9 hookathon, and a good share of them used Reactive Network. The judges did something more useful than count claims: they checked whether each project's reactive contract actually fired a callback on-chain. Six passed that test. This is a look at those

Season 6 is wrapping up. Our 1-month staking pool expires at block 6,055,034 (Monday, July 13th), and with it we're opening the door to Season 7. Season 7 repeats Season 6 in structure: a single 1-month pool. We're finalizing the last details of the

In January 2026, we wrote about Fiet integrating with Reactive Network to take the manual labor out of asynchronous DeFi settlements. That was the promise. Milestone 2 is the delivery: the contracts are live on Arbitrum and Reactive mainnet, and a full end-to-end run is on record, a real settlement

Reactive Network is entering a new era. The first version of REACT tokenomics was built around an Ethereum-style model: no fixed ceiling, validator rewards issued over time, and every network fee burned through real usage. The logic was coherent. It made sense for a young network still proving the shape

There's a question lurking underneath a lot of blockchain engineering that sounds almost too simple to be worth asking: when a transaction lands on a chain, how long until you can be sure it's never coming back off? Not "probably safe" but truly, irreversibly

Season 5 is wrapping up. Our 3-month staking pool expires at block 5,649,633 (around 3 PM UTC on June 10th), and with it, we're opening the door to Season 6.

Something interesting happened in late February 2026. The Ethereum Foundation published a document that, if you squint at it from the right angle, reads like a roadmap toward the kind of consensus design that Cosmos ecosystem chains have been running for years. The document is called the "strawmap"

Somewhere beneath the surface of over a hundred blockchain networks, from Cosmos Hub to Osmosis to Celestia, there's a consensus engine quietly doing the heavy lifting. It's called CometBFT, and unless you've spent time wandering the Cosmos ecosystem, you've probably never encountered

Today, May 25th, we're rolling out the Omni fork for Reactive Lasna. The first testnet built on Reactive Network's new CometBFT-based architecture is live and ready for developers to start building, testing, and experimenting with the changes we've been working toward over the past

Reactive Network is getting a new engine. We're calling this the Omni fork. The consensus layer, the developer experience, and the way reactive contracts work are all being rebuilt. This document covers the technical specifics: what's changing, what stays the same, and what it means if

We spent 2025 building, shipping, and watching a growing cohort of developers push the network forward, stress testing its functionality. As we close out this inaugural year, we've taken stock: what's working, what needs improvement, and where this goes from here. This roadmap is a story

In DeFi Hack Postmortem Part 1, we looked at how Reactive Contracts address the root cause of bridge exploits: the gap between what a validator claims has happened and what actually has happened on-chain. That's the prevention side: stopping the hack before it starts. But prevention only works

On April 18th, 2026, someone sent a fake message to a cross-chain bridge and walked away with $293 million. The target was Kelp DAO, a liquid restaking protocol on Ethereum. The bridge connecting it to other blockchains was configured with a single validator, one computer responsible for confirming whether incoming

Liquidation feels like a shock to many users. Positions weaken gradually: health factor drops, buffers thin, and prices move against you. Then one transaction closes everything. Soft liquidation addresses that gap. Instead of enforcing at a single threshold, it responds to early warning signals and adjusts while the position can

In Intent-Centric Protocols: A Simpler Way to Use Blockchains, we looked at how intent-centric protocols are changing the way people interact with blockchains. Instead of specifying every step of a transaction, you describe the outcome you want and let a network of solvers compete to deliver it. It's
