Zero-Knowledge Proof Subscription Verification

We design and implement custom zero-knowledge circuits tailored to your subscription logic (e.g., time-locks, tiered access, multi-asset payments). Built with Circom and Halo2 for optimal proving efficiency and security.

Deployment of gas-optimized, audited verifier smart contracts to your target chain (EVM, L2s, Solana). We ensure minimal verification cost and seamless integration with your existing payment infrastructure.

Managed proving service with auto-scaling, load balancing, and 99.9% uptime SLA. Handles peak loads for consumer-scale applications without compromising proof generation speed.

End-to-end security from circuit design to production. Includes formal verification of circuit logic, third-party audits (e.g., Trail of Bits), and secure key management for trusted setups.

Architected for regulatory compliance (e.g., GDPR). ZK proofs verify subscription status without exposing user identity or payment details, enabling privacy-preserving business models.

Remove friction by verifying subscription status in milliseconds without exposing user data. Enable one-click access for verified subscribers.

Leverage battle-tested ZK circuits (Plonk, Groth16) and cryptographic libraries audited by Halborn. Your user's subscription data remains private and tamper-proof.

Our managed prover network handles thousands of concurrent verifications with 99.9% uptime. Scale seamlessly without managing complex ZK infrastructure.

Verify subscriptions and mint access tokens on Ethereum, Polygon, Arbitrum, and other EVM chains from a single integration. Future-proof your deployment.

Go from concept to production in weeks, not months. Our SDKs and pre-built circuits for common subscription logic eliminate the need for in-house ZK expertise.

Build with privacy regulations (GDPR, CCPA) in mind from day one. ZK proofs provide cryptographic proof of entitlement without storing or processing personal data.

We conduct a deep technical analysis of your subscription model and existing infrastructure to design a custom ZK circuit architecture. This ensures optimal performance and cost-efficiency for your specific use case.

Our team builds and rigorously optimizes the ZK circuits (using Circom, Halo2, or Noir) for your verification logic. We focus on minimizing proof generation time and on-chain verification gas costs.

Every circuit undergoes a multi-layered security review, including automated analysis and manual auditing by our in-house experts. We provide a comprehensive audit report for your team.

We deliver a production-ready SDK (TypeScript/Go) with clear documentation, enabling your engineering team to integrate ZK subscription checks into your backend and frontend in days, not months.

We benchmark the final solution against your requirements, providing detailed metrics on proof generation speed, verification latency, and infrastructure load to ensure it meets production SLAs.

Receive continuous support including circuit updates for protocol changes, performance monitoring, and access to our team for any scaling or optimization needs post-deployment.
