BUILT FOR COMPLIANCE AT SCALE
Core Engine Capabilities
Our Solana-native engine delivers the performance and auditability required for high-volume, regulated remittance flows. Each component is engineered for sub-second finality and immutable proof generation.
01
Real-Time Transaction Monitoring
On-chain analysis and risk scoring for every transaction before finality, powered by custom Solana programs. Flags suspicious patterns in <400ms to prevent non-compliant settlements.

Frequently Asked Questions
Common questions from CTOs and compliance leads about our Solana-based compliance engine development.
A standard deployment for a production-ready, Rust-based compliance engine on Solana takes 4-8 weeks. This includes design, core development, integration with your existing systems, and a full security audit. For more complex requirements like multi-jurisdictional rule sets, timelines extend to 10-12 weeks. We provide a detailed project plan within the first week of engagement.
