Aztec

Aztec is the leading privacy-first Layer 2 zkRollup on Ethereum, enabling developers to build private smart contracts with fully programmable end-to-end privacy. Developers write contracts in Noir using the Aztec.nr framework, interact with the network through the Aztec.js TypeScript SDK and the Private eXecution Environment (PXE), and use the first-party `aztec` CLI to compile, test, prove, and deploy. Aztec ships an official MCP server and recommended CLAUDE.md/AGENTS.md instructions for AI-assisted development. Backed by a16z, Paradigm, and SV Angel.

Aztec is profiled on the APIs.io network. Tagged areas include Company, Blockchain, Privacy, Zero-Knowledge, and Ethereum.

Aztec’s developer surface includes documentation, API reference, getting-started guide, engineering blog, CLI, changelog, and 12 more developer resources.
