Zero-Knowledge Proof of Solvency Systems

Engineer protocols for lenders and credit issuers to cryptographically prove capital reserves and ability to fulfill obligations without revealing sensitive balance sheet details.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts that power your core business logic, from tokenomics to governance. Our development process is built for security and speed, delivering a production-ready MVP in as little as 2 weeks.

  • End-to-End Development: Full lifecycle support from concept and architecture to deployment and maintenance on EVM or Solana.
  • Security-First Approach: All code follows OpenZeppelin standards and undergoes rigorous internal review before third-party audits.
  • Gas Optimization: Every contract is engineered for minimum transaction costs, a critical factor for user adoption and protocol sustainability.

We don't just write code; we deliver the secure, audited infrastructure your product's trust and value depend on.

Our team specializes in complex implementations:

  • DeFi Primitives: Custom AMMs, lending/borrowing pools, and yield aggregators.
  • NFT Ecosystems: ERC-721A/ERC-1155 contracts with advanced minting, staking, and royalty mechanics.
  • Cross-Chain & Modular: LayerZero integrations and modular contract design for future-proof scalability.

ZK-PROOF OF SOLVENCY SYSTEMS

Core Technical Capabilities We Deliver

We architect and deploy production-ready ZK-based solvency systems that provide cryptographic proof of assets without exposing sensitive data. Our systems are built for financial institutions, exchanges, and custodians requiring institutional-grade security and compliance.

02

Institutional-Grade Proving Infrastructure

Deploy a high-availability proving service with load balancing, automatic scaling, and multi-region redundancy. We guarantee sub-5-second proof generation for standard portfolios and provide a 99.9% uptime SLA for the proving API.

Frequently Asked Questions

Get clear, technical answers about implementing a ZK-based Proof of Solvency system for your exchange, custodian, or DeFi protocol.

A standard deployment for a centralized exchange or custodian takes 4-8 weeks. This includes architecture design, smart contract development, integration with your existing systems, and a full security audit. For more complex DeFi protocols or custom zero-knowledge circuit requirements, timelines extend to 8-12 weeks. We provide a detailed project plan with weekly milestones from day one.
