Zero-Knowledge Proofs for Confidential Collateral
We design and implement custom ZK-SNARK/STARK circuits to prove specific collateral attributes—like ownership or lack of encumbrances—without disclosing the underlying asset's sensitive details.

PROVEN FRAMEWORK
Our Delivery Methodology
Our structured, four-phase approach ensures your confidential collateral system is delivered on time, on budget, and with enterprise-grade security. We focus on measurable outcomes, from initial design to production deployment.
01
Architecture & Design
We design a custom ZK circuit architecture for your specific collateral use case (e.g., private loan-to-value ratios, confidential asset verification). This includes selecting the optimal proving system (Groth16, Plonk, Halo2) and defining the on/off-chain data flow.
