Aztec Labs has acquired ZKPassport however will hold the privacy-focused passport-scanning app absolutely open supply.
Abstract
- Aztec Labs acquired ZKPassport however will hold the iOS app and Noir circuits open supply.
- The privateness app proves identification attributes from authorities IDs with out revealing private information.
- ZKPassport already ran sanctions checks on Aztec’s December 2025 token sale, validating the tech in manufacturing.
Aztec Labs has acquired ZKPassport however will hold the privacy-focused passport-scanning app absolutely open supply. The deal preserves the iOS NFC scanner and Noir circuits.
The Ethereum layer-2 privateness community confirmed the acquisition on Wednesday. ZKPassport, constructed on Aztec’s Noir programming language, lets customers show identification attributes from government-issued IDs with out revealing the underlying private information.
Why the Aztec Labs deal retains ZKPassport public
ZKPassport works by scanning the NFC chip embedded in a passport or nationwide ID, producing a zero-knowledge proof on the consumer’s cellphone, and disclosing solely the particular attribute a service wants.
The app first gained traction on Aztec’s testnet, the place it solved a Sybil-attack downside that was choking the validator set. Inside weeks of integration, the community lifted its each day quota of recent sequencers.
By holding the codebase open supply, Aztec Labs retains the public-good framing that grew the venture. Michael Elliot’s ZKPassport had positioned itself as a non-profit identification resolution earlier than the deal.
“Sooner or later, all crypto will likely be personal,” Aztec Labs CEO Zac Williamson advised crypto.information in a previous interview, framing ZKPassport-style verification as one path to compliant, privacy-preserving on-chain identification.
How the iOS app matches Aztec’s wider stack
ZKPassport’s iOS app already plugs into Ethereum, Base, Aztec, and different EVM chains by way of on-chain verifiers. The acquisition consolidates these rails below one product staff whereas holding integration permissionless for outdoor builders.
Aztec’s broader push has centred on programmable privateness. Its Ignition Chain went dwell in November 2025 as the primary decentralised L2 on Ethereum, and the community entered alpha with a full execution setting for personal good contracts shortly after.
ZKPassport’s Noir circuits additionally underpinned Aztec’s current $AZTEC token sale, the place they ran compliant sanctions checks through the December 2025 continuous-clearing public sale with out leaking participant information.
That use case proved the tech in manufacturing. The acquisition formalises a relationship that had already handed a number of dwell audits, with Consensys Diligence and TU Vienna each contributing safety evaluations.
What the deal alerts for ZK identification competitors
The marketplace for privacy-preserving identification has tightened in 2026. World, Self Protocol, Holonym, Rarimo, and zkEmail all run variations of the identical playbook: client-side proofs, doc scans, selective disclosure.
ZKPassport’s distinguishing function was all the time its document-native method, leaning on the cryptographic signature already baked into ePassports and authorities IDs.
By absorbing ZKPassport whereas holding it open, Aztec Labs successfully claims that infrastructure tier with out forcing rivals off the expertise. The guess is that programmable privateness wins by way of composability quite than enclosure.
Aztec’s testnet attracted greater than 24,000 validators by way of 2025, with ZKPassport-gated humanity checks taking part in a central function within the decentralisation push throughout rival privateness networks. The acquisition aligns the 2 roadmaps for the community’s full mainnet section.
