Aztec Labs Relaunches the zk.money Wallet

Aztec Labs put a private payments wallet back in front of users on 29 September 2026. The Aztec zk.money relaunch September 2026 returns zk.money, a self-custodial wallet on Aztec Network. Payments inside the wallet hide balances, amounts, and recipients. Deposits of USDC, USDT, or DAI from Ethereum stay public. Each deposit, payment, and withdrawal is capped below $2,500, and users share a $50,000 daily deposit ceiling. The product is a limited private payment tool with a public on-ramp, not a fully hidden account from the first dollar.

What happened

Self-custodial means the user holds the keys. Aztec does not hold the balance the way an exchange does. Aztec Network is the system the wallet runs on. zk.money is the wallet. Relaunching it means an earlier version existed, was shut, and is being offered again. The original launched in 2021. Before it was shut it had more than 75,000 wallets and over $100 million in volume. Those figures describe the old product. They are not a count of users of the version that returned on 29 September, and they are not a forecast.

Inside the wallet, a payment hides the balance, the amount, and the recipient. That is the privacy claim for activity that stays inside. It is not a claim that every related fact is hidden. The boundary is the deposit. Deposits of USDC, USDT, or DAI from Ethereum remain public. Those are dollar-linked tokens on Ethereum. Moving one of them into the wallet is still visible, on the accounts used here. A later payment inside the wallet is the step that hides amount and recipient. A user who treats the deposit itself as private has the design backwards.

Users can send to a readable name such as bob.zk.money. That example shows the naming style. It is not a claim that a particular person controls the name. A readable name is a convenience. It does not make the Ethereum deposit private, and it does not change the privacy rule on the internal payment.

The caps are part of the product. Each deposit, each payment, and each withdrawal is capped below $2,500. "Below" means this article will not treat $2,500 as an allowed amount. Users also share a $50,000 daily deposit ceiling. "Share" means the ceiling is common. It is not a promise that each user may deposit $50,000 a day. How the ceiling is split when many people deposit on the same day is not specified. What is specified is that the ceiling is daily, that it applies to deposits, and that users share it.

Joe Andrews, Aztec Labs' CEO, stated a design point rather than a market view. Paraphrased, his point is that an onchain transaction between two people should not publish their financial history. The relaunch moves in that direction, inside the caps, and inside the rule that deposits of those three tokens from Ethereum stay public. This article will not stretch his point into a longer quotation.

Why it matters

Hiding a balance, an amount, and a recipient answers a narrow question: whether two people can move value without laying the payment out in public. Andrews's point is that they should not have to publish that history. The wallet offers that for payments inside zk.money. It does not offer it for the deposit that funds the wallet, and it does not offer it in unlimited size.

The public deposit keeps the on-ramp legible to anyone watching Ethereum. An observer can still see that USDC, USDT, or DAI moved in, even if a later internal payment hides the amount and the recipient. Privacy in this product begins after the on-ramp. That is a smaller claim than a claim that Ethereum itself has been made private, and it is the claim the facts support.

The caps cut the claim again. A tool limited to below $2,500 on every deposit, payment, and withdrawal, under a shared $50,000 daily deposit ceiling, is not a wholesale settlement rail. Large value would have to be split across many actions and would still meet the shared daily deposit limit. The old volume, over $100 million before the shutdown, is history. It is not the capacity of the new caps.

The 2021 figures explain why the name is familiar. More than 75,000 wallets is real earlier use. They do not say why the wallet was shut, and this article will not invent a reason. They also do not say the new wallet inherits the old accounts. A relaunch can restore a name without restoring old balances. Nothing in the shared facts says those balances reappeared.

What's next

What the new wallet does in user counts or volume after 29 September 2026 is not in the facts. The old scale remains a description of the product launched in 2021 and later shut. Anyone comparing the two has to keep the new caps in the comparison: below $2,500 on each deposit, payment, and withdrawal, and a shared $50,000 daily deposit ceiling. Public deposits of USDC, USDT, or DAI from Ethereum remain part of the design.

Andrews's point either fits the product or it does not. Internal payments hide balances, amounts, and recipients. The Ethereum deposit does not. That is the test available now, without a roadmap. Other write-ups' details on fees, conversions, and older technical flaws are omitted because they are not in the shared facts.
