Aztec is the privacy-native Layer 2 on Ethereum. It empowers developers to build applications that protect user privacy while enabling compliance. Backed by a $100M Series B led by a16z, Aztec is led by a team of world-class researchers and cryptographers who invented trustless client-side proving—the innovation that makes privacy-preserving apps on mobile possible. Using zero-knowledge proofs (ZKPs) and the Noir open-source, Rust-like programming language, Aztec is building a secure and scalable privacy layer for the decentralized future.
