ARCHITECTURE
Core Components of Our zk-PoR System
Our modular system provides cryptographically verifiable proof of solvency for DEXs, built on battle-tested zero-knowledge cryptography to ensure user trust and regulatory compliance.
01
Real-Time Asset Attestation Engine
Automated, on-chain verification of exchange-held assets against liabilities. Continuously monitors wallet balances and smart contract states to generate proof inputs without manual intervention.

Frequently Asked Questions
Get clear answers on how we implement verifiable, non-custodial solvency for your DEX.
A standard implementation for a DEX takes 3-5 weeks from kickoff to mainnet deployment. This includes the ZK circuit design, smart contract development, integration with your existing architecture, and a full security audit. Complex multi-asset or cross-chain requirements can extend the timeline, which we scope and quote upfront.
