StarkNet ZK Identity Verification

We architect and deploy custom ZK-based identity protocols using Cairo 1.0, enabling private credential verification and selective disclosure on-chain. Our solutions integrate with existing standards like Verifiable Credentials (W3C) and Semaphore for maximum interoperability.

Our team designs and rigorously audits custom Zero-Knowledge circuits for complex identity logic, ensuring correctness and optimal gas efficiency. We implement formal verification and partner with leading security firms for independent audits.

Build trustless reputation systems and Sybil-resistant mechanisms by leveraging ZK-proofs of unique humanity or credential ownership. We implement solutions like proof-of-personhood and soulbound tokens (SBTs) to prevent spam and fraud.

Enable seamless identity portability across Ethereum L1, L2s, and other ecosystems. We develop secure, non-custodial bridges for ZK identity states and verifiable credentials, maintaining privacy and sovereignty across chains.

Integrate privacy-preserving KYC/AML checks that satisfy regulatory requirements without exposing user data. Our systems generate ZK proofs of compliance, allowing users to verify eligibility for regulated services like DeFi or tokenized assets.

We deploy and manage optimized proving infrastructure to ensure sub-second proof generation for identity verifications at scale. This includes GPU-accelerated provers and load-balanced systems for enterprise-grade reliability.

We implement the zero-knowledge circuits for identity attestations (e.g., proof-of-humanity, credential ownership). We integrate with prover services like Giza or Cartesi to generate and verify proofs off-chain before on-chain settlement.
