Aztec Labs Brings Back zk.money with Enhanced Privacy Features

Aztec Labs is relaunching zk.money, a self-custodial wallet that uses the Aztec Network to conceal payment amounts and recipients while allowing transfers through readable names or links. The new wallet will allow users to deposit DAI, USDC, or USDT from Ethereum, though USDC and USDT are converted to DAI upon entry. This means that only DAI is used inside zk.money.

On the Ethereum network, anyone who knows a person's wallet address can see its balance and trace past transfers. This can expose a business's payments to suppliers or an individual's spending history. With zk.money, this information is hidden once money is inside the system.

The relaunch comes with limits: each deposit, payment, and withdrawal must be below $2,500. All users share a $50,000 daily deposit allowance, which replenishes over time. The documentation describes these caps as a safeguard while the system is new and says raising them would require a new contract.

Aztec Labs plans to raise the limits as confidence grows and after a later version goes live. A deposit costs 35 cents plus Ethereum fees, and a withdrawal costs 20 cents. Users get 100 sponsored transactions a day inside zk.money, but payments must wait if the contract covering their network fees runs out of funds or cannot cover the prevailing fee.
