**Deck:** On-chain governance stripped admin control over Aztec’s rollup contract, freezing the code in place and clearing the technical bar for L2Beat’s top decentralization tier.
Privacy-focused Ethereum layer-2 Aztec said it reached Stage 2 on L2Beat, the highest decentralization rating the rollup tracker assigns. The milestone followed an on-chain governance action that revoked ownership of the rollup contract.
Aztec announced the change Monday afternoon on X. Revoking ownership made the contract code immutable, the network said, leaving no admin able to override the protocol and preserving an escape hatch through which users can always exit. Those three properties map directly to the conditions L2Beat sets for its top tier.
Code Frozen In Place
L2Beat’s Stage 2 is the final rung on its maturity ladder, reserved for rollups fully governed by smart contracts rather than a privileged operator. The framework requires an immutable contract with no admin override, a permissionless proof system, and an exit window that lets users withdraw their funds if they object to an upgrade. L2Beat’s project page lists Aztec at Stage 2.
Most rollups launch with what L2Beat calls training wheels: a multisig or security council that can pause the chain or push upgrades. Stage 2 removes that backstop. With ownership revoked, Aztec’s rollup contract can no longer be changed by its deployers. The escape hatch is the user-side guarantee, a mechanism that lets holders withdraw to Ethereum even if the network’s operators stop cooperating.
Privacy Pitch
Aztec described itself as the only decentralized L2 with privacy native to the protocol. The network runs an Ethereum layer-2 in which transaction privacy is built into the base layer rather than added by individual applications, backed by zero-knowledge proofs, cryptographic shortcuts that let one party prove a statement is true without revealing the underlying data.
The Stage 2 designation arrives months after Aztec’s mainnet went live and weeks after a separate incident on its deprecated infrastructure. A long-shuttered contract from Aztec Connect, the network’s previous product, was drained of roughly $2.1M earlier this month, three years after that system was wound down. The current rollup is a distinct codebase.
Aztec Labs, the team behind the protocol, has continued to build out its privacy stack. It acquired ZKPassport to fold privacy-preserving identity verification into the network. L2Beat tracks one other project under the Aztec banner, the deprecated Aztec Connect, separately at a lower tier.
