We architect, develop, and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis and manual review, before deployment to mainnet.

Core Capabilities of Our ZK Compliance Engine
Our engine enables financial institutions to leverage zero-knowledge proofs for regulatory compliance without sacrificing user privacy or on-chain performance. Built for production at scale.
01
Real-Time Transaction Screening
Automated OFAC/SDN list screening and AML pattern detection using ZK proofs. Validate compliance off-chain and submit a single cryptographic proof, keeping sensitive data private and reducing on-chain gas costs by up to 95%.
< 100ms

Frequently Asked Questions
Get clear answers on how our privacy-preserving compliance engine integrates with your ZK-Rollup to meet regulatory requirements without sacrificing performance.
We deploy a modular, on-chain verification contract and an off-chain prover service that sits alongside your sequencer. Integration typically involves adding a few lines of code to your existing transaction flow to route specific compliance checks (like sanctions screening) through our system. The core rollup logic and user experience remain unchanged. We've integrated with StarkEx, zkSync Era, and Polygon zkEVM-based stacks.
