Overview
- Aztec Labs has reintroduced zk.money, a privacy wallet that was discontinued three years ago, now operating on its privacy-centric Ethereum layer-2, Aztec Network.
- Users can send stablecoins to designated tags like bob.zk.money, ensuring that transactions within the wallet remain confidential, while deposits from Ethereum are still visible.
- During the initial phase, transactions are limited to $2,500, having previously attracted over 75,000 wallets and $100 million in transaction volume.
After a three-year hiatus, Aztec Labs is reviving zk.money.
This Ethereum developer, focused on privacy, relaunched its self-custodial wallet on Tuesday, enabling users to transfer stablecoins without disclosing their balances, amounts, or recipient details.

"Onchain transactions between two individuals shouldn't mean publishing your financial history to the world," remarked Joe Andrews, CEO of Aztec Labs.

In 2021, https://t.co/yRbyJOw31k introduced private transactions to Ethereum, resulting in over 75,000 wallets and $100M in volume.
Today it relaunches on the fully decentralized Aztec Network.

The wallet operates on Aztec Network, characterized by its privacy-first approach as a layer-2 solution that finalizes transactions on Ethereum.
Private operations are executed on the user's device, which creates zero-knowledge proofs—cryptographic confirmations that validate a transaction's legitimacy without revealing its specifics.
However, there are limitations to private payments via zk.money. While transactions within the wallet remain confidential, deposits from Ethereum are public. Users can transfer USDC, USDT, or DAI from an exchange or Ethereum wallet. Additionally, transactions are capped at $2,500, and there is a shared daily deposit limit of $50,000 for all users.
As the wallet is self-custodial, Aztec emphasizes that it cannot access or freeze user funds, nor does it have any privileged administrator access.
The initial version of zk.money was launched in 2021, and it garnered over 75,000 wallets and $100 million in transaction volume before being shelved to focus on developing its network. In 2021, Aztec secured $17 million in funding in a round led by Paradigm, further enhancing zk.money with Aztec Connect, a toolkit designed for integrating its privacy technology with DeFi protocols.
This relaunch occurs as privacy becomes an increasing priority within Ethereum's development agenda. Developers are considering proposals for the upcoming Hegotá upgrade next year that would enable privacy pools to independently manage their transaction fees.
In a recent post, co-founder Vitalik Buterin suggested that specialized applications could achieve "very strong privacy" through zero-knowledge proofs, aligning with his vision for a "cryptographic world computer."
