The decentralized future of Ethereum has taken a major leap forward with the official mainnet launch of Scroll, a community-driven, open-source zkEVM solution designed to scale Ethereum without compromising security or decentralization. After years of rigorous development and testing, Scroll’s zero-knowledge Ethereum Virtual Machine (zkEVM) is now live, offering developers and users a seamless, high-performance Layer 2 (L2) experience that feels just like Ethereum — but faster and more affordable.
This milestone marks a pivotal moment in Ethereum’s evolution, addressing long-standing challenges around scalability, transaction costs, and developer accessibility. By leveraging cutting-edge zero-knowledge proof technology, Scroll delivers a scalable infrastructure that preserves Ethereum’s core values while unlocking new possibilities for Web3 innovation.
What Makes Scroll’s zkEVM Unique?
At its core, Scroll is built on a bytecode-level, EVM-equivalent zkEVM architecture. Unlike other scaling solutions that require developers to rewrite or adapt their smart contracts, Scroll enables direct deployment of existing Ethereum applications — no code changes needed.
This level of compatibility ensures that tools, wallets, and developer workflows function exactly as they do on Ethereum. Whether you're deploying a DeFi protocol, an NFT marketplace, or a blockchain game, the transition to Scroll is smooth and intuitive.
Zero-knowledge proofs are used to batch and compress transactions off-chain before securely submitting them to Ethereum’s mainnet (Layer 1). This process drastically reduces gas fees and increases transaction throughput, all while inheriting Ethereum’s robust security model.
Security First: A Foundation of Trust
Security is not an afterthought at Scroll — it's foundational. From day one, the project has maintained a fully open-source codebase, enabling continuous peer review and transparency. The team employs a dedicated internal security group and collaborates with leading third-party auditing firms to rigorously test every component of the system.
“We take security extremely seriously,” said Haichen, co-founder of Scroll. “Our commitment to openness and thorough auditing ensures that users and developers can trust the network as it scales.”
This proactive approach has been validated through over a year of public testing. The Alpha and Beta testnets collectively processed more than 55 million transactions, with nearly 1 million batches finalized on Ethereum L1. The Sepolia testnet alone attracted over 900,000 wallet addresses and handled more than 6 million transactions in just two months.
With the mainnet launch mirroring the exact configuration of the Sepolia testnet, confidence in stability and performance is high. The Sepolia environment will continue operating as a sandbox for developers to experiment and build new applications.
Developer-Centric Design Driving Web3 Adoption
Scroll’s mission extends beyond technical innovation — it aims to accelerate mainstream adoption of blockchain technology by improving both user and developer experiences.
“Looking ahead, the vast majority of value transfer will happen on Ethereum’s Layer 2s,” said Sandy Peng, co-founder of Scroll. “By making it easier for developers to build real-world applications on Web3, we’re paving the way for millions of new users to join the ecosystem.”
To support this vision, Scroll’s mainnet rollout begins with onboarding key infrastructure providers, followed by broader support for dApps, developer tools, and decentralized services. Over 100 projects have already deployed on Scroll’s testnet, spanning DeFi, gaming, identity, and infrastructure — a strong indicator of ecosystem momentum.
By lowering barriers to entry and maintaining full EVM equivalence, Scroll empowers developers to focus on innovation rather than adaptation.

The Road Ahead: Decentralization as a Priority
Founded in 2021, Scroll was created with a clear mission: build a scalable, secure, and community-owned Ethereum extension using zkEVM technology. While the mainnet launch is a major achievement, it’s only the beginning.
The next critical milestones include the development of a decentralized proving network and a decentralized sequencer — components essential for achieving full decentralization. These upgrades will gradually shift control from centralized operators to a distributed network of participants, aligning with Ethereum’s long-term ethos.
Scroll has also played a vital role in advancing the broader zkEVM landscape. In collaboration with the Ethereum Foundation’s Privacy and Scaling Explorations (PSE) team, Scroll has contributed approximately 50% of the codebase for PSE’s zkEVM implementation. Through research publications and open-source contributions, the team continues to advance knowledge in zero-knowledge cryptography, circuit design, and hardware acceleration.

Frequently Asked Questions (FAQ)
Q: What is zkEVM and why does it matter?
A: zkEVM stands for zero-knowledge Ethereum Virtual Machine. It allows transactions to be verified off-chain using cryptographic proofs, then posted efficiently to Ethereum. This enables faster, cheaper transactions while maintaining Ethereum-level security.
Q: Is Scroll fully compatible with Ethereum?
A: Yes. Scroll is bytecode-level EVM equivalent, meaning any smart contract that runs on Ethereum can be deployed on Scroll without modification.
Q: How does Scroll reduce transaction costs?
A: By batching thousands of transactions off-chain and submitting compact zero-knowledge proofs to Ethereum, Scroll significantly lowers gas fees compared to L1.
Q: Can I use my existing wallet with Scroll?
A: Absolutely. Wallets like MetaMask work seamlessly with Scroll. Bridging assets from Ethereum is simple and well-documented.
Q: What types of projects are building on Scroll?
A: A diverse range including DeFi protocols, NFT platforms, gaming apps, and developer tools. Over 100 projects have already launched on testnet.
Q: Is Scroll decentralized yet?
A: The mainnet launch is centralized in operation but designed for decentralization. Future upgrades will introduce a decentralized prover network and sequencer.
