In 2015, Ethereum revolutionized blockchain as the first decentralized smart contract network. With it, the grand promise of web3 was born: one unified ecosystem to hold Earth’s assets and power its systems.
Composability, or two different applications communicating within a single block, was a breakthrough innovation for Ethereum at this time. But in the pursuit of scale, L2s robbed Ethereum of its core characteristic.
It’s no secret that the cross-rollup user experience is now a mess. Siloed ecosystems, wrapped assets, leaky bridges and blocked use cases – this is the current L2 landscape.
But what if all Layer 2s could function together like a single Layer 1, while still maintaining sovereignty?
Today, we take a major step towards this goal as Javelin becomes agnostic and compatible with any protocol through its unique Superbuilder network. Going forward any chain can be composable regardless of its architecture, solving fragmentation between rollups and their ecosystems.
We believe that Superbuilders like Javelin are the key to unlocking a composable web3 and will power massive cross-chain growth and adoption.
The Dawn of Superbuilders
Until recently, only Layer 1 blockchains like Ethereum were composable systems (guaranteeing atomicity of transactions via monolithic block production). For years, however, it’s been theorized that cross-chain composability could occur when independent protocols were unified at the block-production level.
Although many researchers speculated about Superbuilders, a type of block builder for multiple chains, no one could figure out how to build one.
Last year, the NodeKit team came together to solve this challenge. Harnessing our backgrounds in big data and algorithmic trading, we created Javelin, and turned what was purely theoretical into reality.
The result: multiple, independent chains made composable for the first time ever through Javelin’s groundbreaking Superbuilder technology.
From Siloed To Composable
Rollups now have a choice. Build siloed ecosystems that fragment liquidity, leak value, and introduce bridge risks, or build composable, fully autonomous networks with increased profitability, atomicity, shared liquidity, value accrual, and unlocked use cases.
For web3 to scale into the global decentralized economy, it will need to be an environment of many chains. Just like we don’t all live in one city, we believe that the societies built on top of Ethereum won’t share one sequencer. Instead they will live in clusters, opting into the communities they wish to share composability with.
Making Javelin agnostic has significant implications for delivering this type of seamless cross-chain user experience. With this shift, Javelin will now be able to power a wide variety of products including L2s with centralized/decentralized sequencers, App-Specific Rollups, based preconfirmations, Shared Sequencers, and more.
Perhaps most importantly, Javelin addresses the issue of siloed ecosystems and creates a model for true global composability. Our decision to make Javelin agnostic both strengthens The Composable Network and web3 as a whole, unifying and unlocking the next generation of onchain use cases.
In a world where blockspace is abundant, Composability is all that matters.

The NodeKit Team
