Anza Review | Honest Verdict (2026)

Anza is the primary Solana protocol development firm, responsible for building and maintaining the Agave validator client — the most widely used Solana validator implementation. Spun out from Solana Labs, Anza focuses exclusively on core protocol research and development. The firm maintains the Solana SDK, which includes over 100 modular crates that developers use to build Solana programs. Anza also created Pinocchio, a zero-dependency framework for writing Solana programs with minimal overhead, and contributes to the @solana/kit JavaScript SDK for frontend development. Anza's work directly impacts every user and developer on Solana — validator performance improvements, transaction throughput increases, and new runtime features all flow through their engineering team. The firm played a key role in implementing QUIC, local fee markets, and other critical protocol upgrades. For Solana developers, Anza's SDK, documentation, and developer tooling form the foundation of the development experience. Understanding what Anza builds helps developers stay ahead of upcoming protocol changes and new capabilities.
