Aztec

Privacy-focused Layer 2 for private contracts

Overview

Aztec Protocol provides privacy-first scalability for Ethereum by operating as a Layer 2 zkRollup that enables programmable privacy for smart contracts. Its system bundles multiple off-chain transactions and submits a single validity proof to Ethereum, reducing costs while keeping transaction data confidential through zero-knowledge proofs. Private computations run on a user’s device in a Private Execution Environment, while public functions run on the Aztec Virtual Machine, with developers using the Noir language to write private smart contracts. The company aims to broaden Ethereum adoption by offering end-to-end privacy and scalable, private smart contracts for decentralized applications.

Aztec Connect investigates potential $2.1M exploit on deprecated contract.

Aztec Connect investigates potential $2.1M exploit on deprecated contract. Last updated: June 14, 2026 3:39 pm 6 hours ago Aztec Connect is being investigated for a potential exploit after about $2.1 million moved from the protocol's old Ethereum smart contract on June 14. The affected system is Aztec Connect, a deprecated privacy product that is separate from the AZTEC ERC20 token and the current Aztec Network. The Aztec Foundation said there are no links between the old product and any smart contracts tied to the AZTEC token or current Aztec network infrastructure. The Ethereum transaction was confirmed at 12:26:23 UTC and interacted with the Aztec Connect contract. The transfer included about 908.99 ETH, along with ERC20 assets including 270,513 DAI, 167.89 wstETH, yvDAI, yvWETH, LUSD and yvLUSD. No exploit vector has been confirmed yet. The asset movement is visible onchain, but the public information available so far does not establish whether the transfer came from a specific contract flaw, sequencer-related path, withdrawal logic issue or another mechanism. Old system leaves limited controls. Aztec Connect was already in sunset mode long before the June 14 incident. The old rollup stopped accepting deposits in March 2023, and Aztec's withdrawal-support window ran until March 31, 2024. After that date, Aztec stopped running the sequencer, contract permissions were renounced, and users had to rely on technical withdrawal tooling or community-operated infrastructure. That history limits the immediate response. Aztec Labs has no admin keys or control over the deprecated system, and the contract cannot be paused or upgraded by the team. Any response now depends on investigation, public transaction tracing, user warnings, ecosystem coordination and any available recovery options around the destination address or later fund movement. The incident also shows why old protocol contracts can remain risky even after a product has been discontinued. Assets left inside deprecated systems may still be reachable through code paths that continue to exist onchain, while the original team may no longer have upgrade, pause or emergency-control powers. Recent DeFi security incidents have followed a similar pattern where the core market or current product was not always the direct target. A Fluid rewards drain recently centered on reward distributors rather than Fluid's broader lending and liquidity markets, while April's crypto exploit roundup showed how smaller contracts, bridges, vaults and frontends can create losses even when larger ecosystem infrastructure continues operating. ZK and smart contract risk return to focus. The Aztec Connect incident comes during a year when privacy infrastructure, ZK systems and immutable contracts have drawn more security attention. ZK protocols can add privacy and scalability, but they also create complex risk surfaces across circuits, proof verification, smart contracts, relayers, sequencers and withdrawal logic. A deeper look at ZK crypto risks shows why bugs in privacy systems can be harder to detect and explain than ordinary token-contract issues. Zcash has faced a separate ZK-security crisis this month after an Orchard shielded-pool issue forced a coordinated upgrade. The network first coordinated a protocol update after the Orchard issue, then saw a large ZEC withdrawal after the critical Orchard patch as markets weighed supply-confidence and privacy-system risk. Aztec Connect is a different system, but the timing keeps privacy infrastructure and ZK verification under close market scrutiny. The case is also a reminder that smart contract security does not end when a product is deprecated. Immutable code can keep holding assets, old integrations can remain active, and users may still need block explorers and wallet records to understand what happened. Onchain transaction review remains one of the fastest ways to follow affected assets, especially when a single transaction contains ETH, stablecoins and yield-token transfers. Aztec Labs has said further updates will follow. The immediate public record is the June 14 transaction, the deprecated Aztec Connect contract, about $2.1 million in transferred assets, no stated link to the AZTEC token or current Aztec Network, and no team-controlled pause or upgrade path for the affected system.

Aztec launches decentralized and private Ethereum L2 on mainnet, almost

Aztec launches decentralized and private Ethereum L2 on mainnet, almost. Aztec launched its Ignition mainnet with no centralized operators, opening community staking amid its major token sale and positioning itself as a fully decentralized L2. Ethereum layer-2 network Aztec launched its mainnet Wednesday - albeit with partial functionality - marking the launch of one of the few fully decentralized networks in the ecosystem. According to an Aztec email viewed by Cointelegraph, Aztec has launched its "Ignition" mainnet chain, a functional consensus-producing chain that generates blocks, but without the smart contract execution layer. According to L2Beat, only the trustless, optimistic rollup network Facet v1 and Aztec's old decentralized finance (DeFi) anonymization project, Zk.Money are classed as a stage 2 system with full decentralization. Together with Facet, Aztec is among the few protocols with no centralized "training wheels," as ownership of the rollup contract was renounced, and Aztec is neither a rollup processor nor an operator. Users or third parties must run the rollup system themselves to withdraw or transact. In an email sent to the Aztec mailing list subscribers, the Aztec team highlighted that "neither the Aztec Foundation, core team, nor investors can run nodes, stake, or participate in governance for the next 12 months." "This makes Aztec the first community-launched L2 in Ethereum history," the team told subscribers. Aztec had not responded to Cointelegraph's request for comment by publication. Aztec staking is now live. Aztec staking is now available to holders, allowing them to participate in network consensus, earn block rewards and shape governance decisions. The email suggests that early stakeholders receive higher rewards because "early participants benefit from distributing block rewards amongst fewer stakers." The staking dashboard indicates that 107.2 million AZTEC tokens are currently staked. Both the investors and the development team are currently barred from staking, so it is likely that those funds are sourced from the 200 million AZTEC sold in the genesis sequencer sale, which targets whitelisted community members explicitly to bootstrap the mainnet. The minimum stake amount (also applicable to delegated stakes) is 200,000 AZTEC, equivalent to about $6,000 at the prices of the ongoing community-only Continuous Clearing Auctions phase. Still, the tokens may be sold at higher prices than the current $0.03 per AZTEC if demand increases. The ongoing token sale. Aztec is currently in the whitelisted community members-only phase of its token sale, attracting $2.77 million worth of assets from 2,209 unique bidders since its opening on Nov. 13. This phase will close on Dec. 1, just before the public sale starts on Dec. 2 and closes on Dec. 6. The tokens purchased through the sale will be locked for a minimum of 90 days and up to 12 months, depending on whether the community votes to release them early. The sale will distribute 1.547 billion tokens, representing 14.95% of the total supply. Aztec claims that the token sale is taking place at a 75% discount relative to the implied network valuation from previous fundraising efforts. According to ICO Drops data, Aztec raised $2.1 million in its seed round, $17 million in its Series A, and $100 million in its Series B funding rounds. Backers include Ethereum co-founder Vitalik Buterin, Coinbase Ventures, Paradigm, Consensys, Andreessen Horowitz and HashKey Capital, among others. Still, Aztec's own token sale disclaimer warns that "any reference to a prior valuation or percentage discount is provided solely to inform potential purchasers of how the initial floor price for the token sale was calculated." The floor price currently stands at 0.000010 ETH, or about $0.03 per AZTEC - putting the project at a fully diluted valuation of $310 million. The disclaimer also notes that unsold tokens "may be claimed back by the Foundation." On Dec. 6, a Uniswap pool containing 273 million AZTEC (2.64% of supply) will go live to bootstrap liquidity. Tokens bought on the secondary market will not be subject to lockups.

Ignition Chain goes live: Aztec Network introduces privacy-focused Ethereum Layer 2. * F. Bustos * Published: November 20, 2025 * 12:55 pm * Updated: November 20, 2025 * 1:19 pm Home - flash news - Ignition Chain goes live: Aztec Network introduces privacy-focused Ethereum Layer 2. Aztec Network announced the launch of Ignition Chain, its new privacy-focused Layer 2 on Ethereum, according to an official statement shared on X. The team confirmed that the protocol is now operating with a fully decentralized consensus layer on the Ethereum mainnet, marking a key milestone for on-chain privacy infrastructure. The network uses zero-knowledge cryptography (ZK) to process transactions without exposing sensitive data, aiming to enable private DeFi activity while maintaining Ethereum-level security. The deployment is expected to benefit developers, institutions and users seeking lower fees with built-in confidentiality, a feature still limited across most existing Layer 2 solutions. The initiative also signals growing demand for privacy-centric scaling tools as regulatory scrutiny increases worldwide. Aztec stated that the next phase will include performance audits on validators and the rollout of additional developer tools. The project also plans to expand access to new node operators through a public staking program, gradually opening participation to third-party validators.
