ZK Identity for Access Control

We implement and optimize zk-SNARKs and zk-STARKs for identity verification. Our systems generate proofs in under 2 seconds, enabling real-time access decisions without exposing user data.

• Protocols: Groth16, Plonk, Halo2
• Languages: Circom, Noir, Cairo
• Use Cases: Age verification, KYC compliance, credential checks

Deploy gas-optimized, audited verifier contracts to Ethereum, Polygon, and other EVM chains. We handle the complex cryptography so you can focus on application logic.

• Standards: EIP-4337, EIP-712 compatible
• Audits: Third-party reviewed by leading security firms
• Features: Batch verification, upgradeable proxies

Implement W3C-compliant DIDs and Verifiable Credentials (VCs) for portable, user-owned identities. Our SDKs simplify issuing, holding, and presenting credentials across applications.

• Standards: W3C DID, Verifiable Credentials Data Model
• Methods: did:ethr, did:key, did:web
• Storage: IPFS, Ceramic, or your own backend

Design and deploy granular permission systems using ZK proofs. Users prove they meet criteria (e.g., "holder of NFT #X", "score > Y") without revealing the underlying asset or data.

• Models: Role-Based (RBAC), Attribute-Based (ABAC)
• Integration: Seamless with existing auth providers
• Logging: Off-chain, privacy-first audit trails

Build systems that satisfy regulatory requirements like GDPR's "Right to be Forgotten" and financial KYC/AML rules. Our architecture enables selective disclosure and proof of compliance.

• Focus: Data minimization, user consent, auditability
• Tools: Proof of non-inclusion, time-locked credentials
• Reporting: Generate compliance reports without compromising privacy

Accelerate integration with our TypeScript, Python, and Go SDKs. Comprehensive APIs and documentation get your team building in days, not months.

• Full Suite: Proof generation, verification, DID management
• Environments: Node.js, Browser, Mobile (React Native)
• Support: Dedicated technical account management

Implement privacy-preserving KYC/AML verification for DeFi protocols. We build systems that prove user credentials without exposing sensitive data, enabling regulatory compliance while preserving user sovereignty.

Secure, sybil-resistant voting for on-chain treasuries. Our ZK identity solutions ensure one-person-one-vote by proving unique humanity or credential ownership, eliminating bot manipulation in critical governance decisions.

Create exclusive token-gated experiences and communities. We develop smart contracts that verify ZK proofs for token ownership, membership status, or achievement badges to control access to content, events, or services.

Streamline compliant onboarding for TradFi institutions into Web3. Our infrastructure verifies accredited investor status, corporate credentials, and jurisdictional licenses using zero-knowledge proofs, enabling secure capital deployment.

Enable underwriting for on-chain lending without exposing financial history. We build systems that generate ZK proofs of creditworthiness from off-chain data sources, allowing for risk assessment with complete user privacy.

Manage unified identity and permissions across multiple blockchains. Our solutions use portable ZK proofs to maintain access control states, allowing users to prove their rights on any connected chain without re-verification.
