Confirmed! Privacy king Aztec clears public fundraising $ETH, is this a technical cash-out or a collapse of confidence?

On April 18th early morning, on-chain data showed that the Aztec project team transferred approximately 5,020 ETH to Coinbase. This transfer is the last of the ETH raised from last year’s public auction.

Looking back, in December last year, during that auction, Aztec sold about 1.55B of its tokens, accounting for 14.95% of the total supply, raising a total of 19,388.46 ETH. Subsequently, in February this year, at the time of token generation, the team withdrew 4,234.6 ETH to form a liquidity pool, with the remaining funds gradually transferred to exchanges over the past three months.

This movement of funds provides a timely perspective to examine Aztec. Over the past few years, the market has listed it among the “top-tier projects,” due to early expertise of the founding team in zero-knowledge proofs, the widespread influence of the PLONK proof system, the spillover value of the Noir development language, and backing from top capital firms like Paradigm and a16z.

However, these labels are more like historical evaluations. A more practical question is: what has it actually delivered, what is still missing, and whether privacy is truly a large enough business opportunity.

Aztec’s prominence primarily stems from its position at the forefront of the privacy narrative. The team started in 2017, initially exploring enterprise debt on the blockchain, but shifted to programmable privacy due to transparency barriers on-chain. In 2018, it demonstrated an early prototype of private asset transfers on Ethereum; in 2019, it released the influential PLONK proof system. Since then, the team has launched zk.money, Aztec Connect (later discontinued), and developed Noir into a more general zero-knowledge development language.

The capital market once valued it highly: a $17 million Series A led by Paradigm in December 2021; a $100 million Series B led by a16z crypto in December 2022. However, “top-tier” essentially reflects market expectations, meaning it is seen as a bellwether for the privacy track—if even it can’t succeed, this direction might indeed be very challenging.

Looking at recent progress, Aztec’s pace is not slow. On March 31, it officially announced the launch of Alpha Network, bringing private smart contract execution to the public network. Developers can choose between public or private modes within the same system, building applications around data, identity, and computation privacy layers.

However, blockchain data reveals another side. According to its blockchain explorer, total transaction count is only 6,938, with just 39 active contracts, and an average block time of about 68.8 seconds. This indicates the network is still in a very early stage of usage, with a significant gap from the performance levels needed for high-frequency interactions or large-scale applications.

The official definition of this stage is also quite restrained. The Alpha phase focuses on gradually completing tools, fixing bugs, and optimizing user experience, rather than expanding throughput. The Ignition phase launched in November last year aimed to verify the stable operation of the decentralized network’s underlying infrastructure. In Alpha, trading functions are further opened, and private contract execution is introduced.

The current official targets include about 1 TPS and roughly 6 seconds per block, with a clear statement that there will be no default state migration between different Alpha versions. This means the network is still in a rapid iteration and reconstruction phase. According to the roadmap, only when entering the Beta stage will the goals be raised to over 10 TPS and shorter block times.

Objectively, Aztec faces many challenges, not all of which stem from regulation. First, security issues remain prominent. In March, the team disclosed a critical vulnerability in Alpha v4, which could, in the worst case, cause protocol disruption or user funds loss. Fixes are expected with v5 in July. For a network just entering Alpha, such disclosures are necessary but also indicate it is still far from being “trustworthy for value-bearing.”

Second, performance issues. Current performance cannot support complex DeFi or high-frequency applications.

Third, the real demand for privacy has not been fully validated. Industry consensus holds that “privacy is important,” but “important” does not mean “with sustained paying usage.” Retail users care more about cost, speed, and liquidity; developers focus on toolchain maturity; institutions weigh compliance boundaries and auditability. If privacy applications do not bring clear efficiency improvements over public chains, it’s hard to build a large user base based solely on values.

Fourth, Aztec’s past product experiences also serve as warnings. zk.money and Aztec Connect were shut down in 2023, with official explanations citing the inability to support both old products and the development of a new encrypted zkRollup simultaneously. The key question is whether the new architecture can avoid repeating the same mistakes.

In the updated roadmap this March, Aztec emphasizes programmable privacy, network decentralization, and proof system optimization. But more directly, what Aztec most needs now is not storytelling but validation. It must verify whether private smart contracts can meet real needs, whether decentralized privacy networks can balance security and performance, and ultimately whether “compliant privacy” is a sufficiently clear market product.
