Overview

Description

0xKYC is an open-source project developing privacy-preserving digital identity verification software. Its stack checks liveness and identity, generates zero-knowledge onchain attestations, and supports reusable, permissionless, interoperable verification across wallets and chains. It is aimed at Web3 games, onchain KYC use cases, fairdrops, DAOs, and other organizations seeking to prevent duplicate accounts, fraud, and sanctions exposure while protecting users’ anonymity. The project previously operated as a for-profit company and is currently being revived by its open-source community; its Discord bot is not currently operational.
