What is the Optimism Superchain?
The Superchain is a vision of a unified network of Layer 2 blockchains built using the OP Stack, Optimism's open-source development framework. These chains, called OP Chains, share infrastructure, security, and standards to enable seamless communication and scalability across Web3.
Superchains benefit from shared bridges, governance, and security guarantees, creating a more consistent and scalable foundation for decentralized applications.

FAQ: Understanding the Superchain Ecosystem
What is the OP Superchain?
The OP Superchain is an evolving network of Layer 2 blockchains built using the OP Stack: a modular, open-source framework developed by Optimism. Each of these chains, called OP Chains, shares core infrastructure, governance models, and security features while still remaining independently operated.
Think of it as a constellation of chains that function like one, allowing Dapps, users, and devs to move across networks more easily. The Superchain vision is to create a unified, scalable Web3 experience that feels like using a single network, even though it's made up of many chains.
What is an OP Chain?
An OP Chain is any blockchain that’s deployed using the OP Stack and therefore becomes part of the Superchain ecosystem.
An OP Chain is any blockchain that’s deployed using the OP Stack and therefore becomes part of the Superchain ecosystem.
Shared bridge infrastructure for L1<>L2 activity
Common standards for contracts, tokens, and tooling
The ability to interoperate more easily with other OP Chains
Collective upgrades and community governance under the Optimism Collective
Notable OP Chains include Optimism Mainnet, Base, Zora, Ink, Unichain, Soneium, World Chain, and Lisk, among many others. You can view the full list of Superchains in the directory above.
What is the Superchain ecosystem?
The Superchain ecosystem is the broader community of chains, developers, applications, and users building on OP Stack-based networks.
It includes:
Infrastructure providers (like Blockscout) powering core services
End-user Dapps like wallets, DEXs, games, and NFT marketplaces
Governance bodies like the Optimism Collective that guide coordination
The goal is to create a more unified, efficient blockchain environment where resources, tools, and users can move freely across many chains, without each one having to build from scratch.
Why does the Superchain matter?
In Web3 today, there’s a problem: fragmentation. Every new chain tends to build its own explorers, its own bridge, its own rules. That slows everything down.
The OP Superchain flips that. By sharing code, governance, and infra through the OP Stack, it enables:
Faster launches for new chains
A consistent developer experience
Shared liquidity and tools
Easier UX for users moving between ecosystems
It’s simply a more scalable model for blockchain growth and a big reason why OP Stack adoption is rising fast.
What is a Superchain block explorer?
A block explorer is a tool that lets users, devs, and analysts search, verify, and interact with blockchain data. Blockscout is the most widely used open-source block explorer across the Superchain, currently powering over 25 OP Stack networks.
It offers:
Transaction and account search
Smart contract verification
Gas usage and fee data
Cross-chain visibility between L1 and L2
Multichain support through a single interface
Whether you're looking up a wallet address, tracking a bridge deposit, or exploring newly deployed Dapps, a Superchain block explorer like Blockscout gives you the transparency and tools you need.

Why do Superchains need their own block explorers?
Each OP Chain in the Superchain ecosystem functions as an independent blockchain, with its own deployed contracts, native tokens, user base, and developer tooling. While the OP Stack ensures interoperability and shared infrastructure, the data generated by each chain lives within its own environment.
That’s why dedicated block explorers matter. They offer transparency for chain-specific activity, give developers a place to verify contracts, and act as the first stop for new users entering the ecosystem. Blockscout supports this modular model by giving every OP Chain a full-featured, open-source block explorer while maintaining a consistent user experience across the entire Superchain network.
What makes Blockscout different from other Superchain block explorers?
Blockscout is the most widely deployed open-source block explorer in the EVM ecosystem, and it’s built from the ground up for multichain support. Unlike walled-off explorers, Blockscout is fully transparent, customizable, and actively developed in the open. It already supports over 1000 EVM networks and supports the majority of live Superchain deployments today.
Beyond basic data lookups, Blockscout enhances the user experience with features like human-readable domain support, built-in Dapp discovery through Dappscout, smart AI-powered transaction interpretation, and bridge-aware tracking for L1 <> L2 flows. It’s not just a tool for reading onchain data, it’s a window into the Superchain ecosystem that helps users and developers explore, understand, and interact with their chain of choice.
Can I compare activity across OP Chains with Blockscout?
Yes. Blockscout’s dashboards and real-time stats make it easy to track and compare performance across Superchains. Whether you're monitoring contract deployment trends, transaction throughput, transaction batches, gas fees, or user growth, each chain’s block explorer provides a clear and consistent data view.
This visibility is crucial for anyone looking to understand how OP Chains are growing, how users are moving assets between layers, and where developer activity is concentrated. For ecosystem builders and chain operators, these insights help inform go-to-market strategy and ecosystem development. For users and researchers, they offer a transparent way to assess what’s happening under the hood across the Superchain network.
What is a Rollup-as-a-Service (RaaS) provider?
RaaS providers help developers and teams launch their own rollups (Layer 2 blockchains) without having to manage complex infrastructure. They offer tools, templates, and services to simplify deploying, running, and maintaining a new OP Chain.
Some popular RaaS providers in the Superchain ecosystem include:
How do I launch my own OP Rollup?
Launching an OP Rollup means building a chain using the OP Stack, the open-source framework powering the Superchain. You can deploy your own OP Chain by working directly with the OP Stack codebase or partnering with a RaaS provider who handles infrastructure for you.
If you're building your own Superchain rollup, Blockscout offers a fast way to launch your own open-source block explorer with Autoscout. Get your explorer live in minutes with no manual infra setup.
