THE ARCHITECTURAL ADVANTAGE
Why Custom ZKPs Outperform Generic Solutions
Generic ZKP frameworks introduce unnecessary overhead and security risks. Our tailored circuits are engineered for your specific application logic, delivering superior performance and security.
01
Circuit-Specific Optimization
We design zero-knowledge circuits that mirror your exact business logic, eliminating the computational bloat of one-size-fits-all frameworks. This reduces proof generation time by up to 70% and verification gas costs by over 50%.

Faster Proof Generation
> 50%
Lower Gas Costs
02
Proven Security Posture
Every custom circuit undergoes formal verification and peer review by our in-house cryptographers. We implement domain-specific constraints that eliminate entire classes of vulnerabilities generic frameworks cannot address.

Seamless AppChain Integration
Our ZKPs are built natively for your chosen AppChain stack (Polygon CDK, Arbitrum Orbit, OP Stack). We handle the complex integration of provers, verifiers, and state management, ensuring sub-second finality.
