StarkWare launches Private KYC on Starknet

Written by Isaac FrancisPublished Jun 24, 2026, 5:29 AM

StarkWare unveiled a Private KYC system on Starknet that uses zero-knowledge proofs to verify identity attributes without exposing personal data.
The launch addresses growing concerns around data breaches, with the US recording 3,322 data compromises in 2025.
The company said the technology could help institutions meet compliance requirements while reducing the amount of sensitive information they store.

StarkWare introduced a Private KYC demonstration on Starknet, allowing users to complete identity verification checks without revealing full personal information such as passport details or home addresses.

The launch comes as concerns over data security continue to grow, with 3,322 data compromises reported in the United States during 2025 and the average global cost of a data breach reaching US$4.4 million, according to StationX.

“Whether you need to prove you’re over 18, hold a valid credential or meet an eligibility rule, verification should only confirm the precise fact,” said StarkWare.

The system uses Starknet's STRK20 privacy features and zero-knowledge STARK proofs to verify specific attributes while keeping identity data encrypted within a user's wallet, with verifiers able to confirm eligibility through an onchain registry.

StarkWare said the technology allows institutions to validate compliance requirements without collecting full identity records, while the Starknet (CRYPTO:STRK) token was unchanged following the announcement.

Users begin the process by scanning their passports with a smartphone camera and NFC reader, after which identity details are encrypted and selective proofs can be generated for verification requests.

The launch follows broader industry efforts to combine privacy and compliance, with StarkWare comparing its self-custody approach to systems such as Worldcoin's World (CRYPTO:WLD) ID, while citing major historical data breaches including the 2020 Ledger customer database leak affecting more than 270,000 records.

At the time of reporting, Starknet price was $0.03179.
