# Intro to Quadrata Passport Quadrata Web3 Passport is a privacy-preserving, sybil-resistant technology that brings identity, compliance, and reputation to DApps built on public blockchains. ### How it works Businesses and consumers onboard onto Quadrata by attaching their wallets to an identity passport. The Quadrata Passport is issued as a non-transferrable NFT. DApps integrated with Quadrata can check [passport attributes](/passport-issuer/additional-information/passport-attributes.md) to verify: * If the user has a passport. * If the user owns more than one wallet. * The user's AML risk score. * From which country the passport was issued. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
