Ethereum users get another way to pay privately as zk.money returns after three years

“Onchain transactions between two individuals shouldn't mean publishing your financial history to the world,” Joe Andrews, CEO of Aztec Labs, said in a statement.

Andrews added that Aztec Labs chose DAI because it considers it “the most decentralized of the mass-market stablecoins used today on Ethereum.” He said the wallet could support other assets later.

Ethereum already has apps that hide payments, though transfers from an ordinary wallet remain public. Its developers are weighing changes for the planned 2027 Hegotá upgrade that could let privacy apps handle transaction approvals and fees with less help from outside services. Those proposals are still under consideration, while Aztec Labs is bringing back a wallet people can use on its own network.

What zk.money can and cannot hide

Moving money into the system still leaves a public trace, however. Aztec’s documentation says a deposit from Ethereum reveals the sender and amount, even though the recipient on Aztec can remain private.

The relaunch comes with limits, however. 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 those caps as a safeguard while the system is new and says raising them would require a new contract.
