# Aztec > Build with ‍the power of privacy on Ethereum Aztec is a privacy-first Layer 2 for Ethereum that uses zero-knowledge proofs for confidential transactions with public verification. Aztec is a privacy-first Layer 2 scaling solution for Ethereum that uses zero-knowledge proofs. The protocol lets users conduct private transactions on public blockchains with cryptographic verification. Applications built on Aztec offer user privacy while maintaining Ethereum's security benefits. Aztec focuses on providing the infrastructure for developers to create privacy-preserving applications that protect sensitive data. - Type: Company - Sector: Infrastructure - Status: Active - Founded: 2017-01-01 - Profile: https://thegrid.id/profiles/aztec ## Products - [Aztec 3](https://thegrid.id/profiles/aztec): Aztec 3 is a Layer 2 solution that uses zero-knowledge technology to provide private transaction capabilities on Ethereum while maintaining public verifiability and security. (L2, Live, Main Product) - [Noir](https://thegrid.id/profiles/aztec): Noir is a domain-specific language for creating zero-knowledge proofs. Noir enables developers to build private applications while maintaining compatibility with public blockchain infrastructure. (Developer Tooling, Live) - [Sandbox](https://thegrid.id/profiles/aztec): Sandbox is a local development environment that enables developers to build and test privacy-focused smart contracts. The Sandbox simulates Aztec's Layer 2 functionality, allowing for experimentation with private and public execution environments.
