Quadrata is a privacy-preserving on-chain identity network for Web3, issuing a non-transferable (soulbound) NFT "Passport" that binds verified identity, compliance and reputation attributes to a user wallet without storing personal data on-chain. Integrators use the Quadrata SDK and REST API to onboard users (KYC), businesses (KYB), and accredited/sophisticated investors, run AML risk and on-chain wallet screening, request consented privacy (PII) data, and query passport attributes on-chain via smart contracts or off-chain via API. Passport attributes include DID (sybil resistance), AML score, COUNTRY, IS_BUSINESS, INVESTOR_STATUS, and Cred Protocol credit score. Supported networks include Ethereum, Polygon, Arbitrum, Optimism, Avalanche, Evmos, and KAVA.
