Core Capabilities of Our ZK Proof of Solvency Service

Our service delivers cryptographic proof of your exchange's or custodian's solvency, providing immutable, real-time assurance to users and regulators without exposing sensitive data.

01

Real-Time Reserve Verification

Continuously prove your total assets exceed total user liabilities. We generate ZK proofs on-demand or on a schedule, enabling public verification of solvency at any moment, not just in periodic reports.

PREDICTABLE, TRANSPARENT, AND SECURE

Our Delivery Process: From Assessment to Live Attestation

A structured, four-phase engagement model designed for technical leaders who need a reliable, auditable, and production-ready ZK Proof of Solvency system without operational overhead.

01

Phase 1: Architecture & Threat Assessment

We conduct a deep technical review of your custody model, asset mix, and regulatory requirements to design a zero-knowledge circuit architecture that balances proof efficiency with security. Deliverables include a formal threat model and a detailed technical specification.

Frequently Asked Questions

Get clear answers on how Chainscore Labs delivers secure, auditable, and trustless solvency proofs for your platform.

A standard implementation takes 4-8 weeks from kickoff to production deployment. This includes requirements analysis, circuit design, smart contract development, integration with your existing infrastructure, and a full security audit. For more complex multi-asset or cross-chain proofs, the timeline may extend to 12 weeks. We provide a detailed project plan during the initial consultation.
