Ethereum Gets Another Privacy Boost as Aztec Brings Back zk.money

Aztec Labs has relaunched its self-custodial privacy wallet zk.money on its Aztec Network, a privacy-focused Ethereum layer-2. The wallet lets users send and receive stablecoins to human-readable tags while keeping on-wallet payments private, though deposits from Ethereum remain public and individual transactions are capped in the early rollout.

Ethereum Gets Another Privacy Boost as Aztec Brings Back zk.money

Why It Matters

The relaunch revives a privacy tool that previously attracted substantial usage and sits amid growing interest in on-chain privacy for Ethereum, including developer discussions about protocol upgrades and zero-knowledge approaches. Restoring zk.money on a dedicated privacy layer-2 could influence how users and developers approach private payments and tooling on Ethereum.

Key Facts

Project: zk.money (relaunched by Aztec Labs)
Network: Aztec Network (privacy-first Ethereum layer-2)
Supported tokens: USDC, USDT, DAI
Address resolution: Human-readable tags like bob.zk.money via ENS
Private vs public: Payments inside zk.money are private; deposits from Ethereum are public

Aztec Labs has reintroduced zk.money, its self-custodial privacy wallet, running on the company's Aztec Network layer-2. The wallet allows users to send and receive stablecoins using readable tags that resolve through the Ethereum Name Service (ENS). According to Aztec, transactions executed within zk.money conceal balances, amounts, and recipients by using zero-knowledge proofs generated on users' devices.

The relaunch restores functionality the project first offered in 2021. Back then, the original zk.money attracted more than 75,000 wallets and processed over $100 million in volume before Aztec paused the product to focus on building its own network. Aztec previously raised $17 million in a round led by Paradigm and also developed Aztec Connect to integrate its privacy technology with DeFi protocols.

While payments inside the wallet are private, Aztec notes that deposits originating from Ethereum remain public on-chain. Users can fund zk.money with USDC, USDT or DAI from exchanges or external Ethereum wallets. Early rollout limits include a $2,500 maximum per transaction and a shared $50,000 daily deposit ceiling. Aztec also emphasizes that the wallet is self-custodial, meaning the company cannot move or freeze users' funds.

The relaunch arrives as privacy gains prominence in Ethereum development. Upcoming protocol discussions, including proposals for the Hegotá upgrade, consider mechanisms that could enhance privacy for on-chain pools, and Ethereum co-founder Vitalik Buterin has highlighted zero-knowledge proofs as a path to strong privacy for specialized applications.
