Quadrata primary sources — 2026-04-30

Project status in this pass

  • No canonical standalone Quadrata whitepaper or litepaper surfaced.
  • The clearest current source of truth is the official site and the developer/integration docs.

Primary-source snapshots

1) Official homepage

  • URL: https://quadrata.com/
  • Key excerpt:
    • Frames Quadrata as the “Single Sign-On for Compliant Web3.”
    • Describes the Quadrata Passport as a privacy-preserving, soulbound token attached to a wallet.
    • Highlights identity verification, AML screening, wallet screening, KYB/business verification, sybil-resistant identities, country checks, age checks, accredited-investor status, and on-chain credit reputation.
    • Explicitly says no personally identifiable information is stored onchain.

2) Integration overview

  • URL: https://docs.quadrata.com/integration
  • Key excerpt:
    • Describes Quadrata Web3 Passport as privacy-preserving, sybil-resistant technology bringing identity, compliance, and reputation to DApps on public blockchains.
    • Says businesses and consumers onboard by attaching wallets to a passport issued as a non-transferable NFT.
    • Lists support for individual identity verification, KYB, AML screening, wallet screening, country verification, age verification, and US accreditation checks.
    • Says Quadrata is supported on Ethereum, Polygon, Arbitrum, Optimism, Avalanche, Evmos, and Kava.

3) Passport attributes page

  • URL: https://docs.quadrata.com/integration/introduction/passport-attributes.md
  • Key excerpt:
    • Documents six core machine-readable attribute types: DID, AML, COUNTRY, IS_BUSINESS, INVESTOR_STATUS, and CRED_PROTOCOL_SCORE.
    • Notes the DID is sybil resistant, AML is a 1–10 risk score, country uses ISO-3166-1 alpha-2 values, and the credit score ranges from 300 to 1000.
    • Important because it shows the passport is meant to be consumed programmatically by applications and contracts.

4) Query attributes docs

  • URL: https://docs.quadrata.com/integration/how-to-integrate/query-attributes
  • Key excerpt:
    • Shows two main integration paths for attribute access: via smart contract and via API.
    • Also documents a “Query Helper” library contract for onchain integrations.
    • This is a strong clue that Quadrata is infrastructure/middleware rather than just a hosted onboarding form.

5) Smart contracts page

  • URL: https://docs.quadrata.com/integration/additional-information/smart-contracts.md
  • Key excerpt:
    • Defines the contract surface as QuadGovernance, QuadPassport, and QuadReader.
    • Publishes production contract addresses across Ethereum mainnet, Polygon, Avalanche, Arbitrum, Optimism, Evmos, Kava EVM, zkSync Era, and Base, plus testnet addresses.
    • Notes passports can be minted through the normal onboarding flow or through a sandbox on testnets.

6) SDK/API onboard-status page

Working conclusion

Quadrata is best cataloged as reusable identity-and-compliance passport infrastructure for public blockchains. The combination of a soulbound passport NFT, queryable machine-readable attributes, fixed onchain reader contracts, and SDK/API onboarding-state checks makes it more than a generic KYC provider or a simple proof-of-personhood badge.
