Aztec Network launches Alpha mainnet, the first Ethereum L2 to support privacy smart contracts

By: rootdata|2026/04/01 13:42:02

The privacy chain Aztec Network, supported by a16z, officially launched Alpha Network, becoming the first Ethereum Layer 2 with a complete private smart contract execution environment, which was previously approved by a unanimous community governance vote.

Aztec integrates privacy at three levels: private data supports confidential transactions and RWA transfers; private identity allows for selective disclosure to meet compliance requirements; private computation hides on-chain behavior, opening up space for privacy DeFi and gaming applications. Contracts are written in the Rust-style language Noir, with privacy logic executed on the user side to generate zero-knowledge proofs, settling on Ethereum approximately every 12 seconds.

However, this launch comes with a significant warning, as Aztec disclosed known serious security vulnerabilities, with auditing still ongoing. The team advises users to only deposit funds they can afford to lose.
