Scroll was designed by and for Ethereum Developers. Scroll is a fast, reliable, and scalable Layer 2 Blockchain that extends Ethereum capabilities. This allows apps to scale without surprises. Existing Ethereum apps can be migrated to Scroll at a significant cost reduction thanks to bytecode compatibility. Our open-source development approach brings together the best ideas from contributors who share similar values, resulting in more secure and better designed systems. Scroll is a community-driven initiative that redefines and evolves Ethereum's roadmap. Scroll uses advanced EVM models that have been battle-tested, as well as rigorous audits, to ensure our foundation is rooted firmly in security and reliability. Scroll protects its developers and users from vulnerabilities by prioritizing code safety through open source collaboration.
