Core Capabilities of Our Compliance Engine
Our StarkNet ZK-Rollup compliance engine is engineered for financial institutions, providing the regulatory safeguards and operational transparency required for institutional adoption.
01
Real-Time Transaction Monitoring
Automated screening of every L2 transaction against OFAC, EU, and other global sanctions lists with < 100ms latency. Prevents non-compliant transfers before they are finalized on-chain.
