FROM COMPLIANCE BURDEN TO COMPETITIVE ADVANTAGE
Business Outcomes: Why Privacy-Preserving KYB Matters
Traditional KYB processes expose sensitive corporate data and create friction. Our ZK-enabled KYB service transforms compliance from a cost center into a strategic asset, delivering measurable business results.
01
Secure Onboarding at Scale
Verify corporate clients in minutes, not weeks, without exposing their private ownership structures or financial data. Our zero-knowledge proofs validate AML/KYC compliance while keeping the underlying data confidential.

A Technical Comparison for CTOs
ZK KYB vs. Traditional Corporate Verification
How our zero-knowledge proof KYB service compares to conventional corporate onboarding methods across critical operational and compliance dimensions.
| Verification Factor | Traditional KYB | Chainscore ZK KYB |
|---|---|---|
Time to Onboard Customer | 5-10 business days | < 24 hours |
Data Privacy & Exposure | High (PII shared with 3rd parties) | Zero (ZK proofs only) |
Compliance Audit Trail | Manual, fragmented records | Immutable, cryptographically verifiable |
Integration Complexity | High (APIs, manual reviews) | Low (Smart contract or API calls) |
Ongoing KYC/AML Refresh | Manual, periodic re-screening | Automated, real-time proof refresh |
Cross-Border Compliance | Jurisdictional silos & complexity | Unified cryptographic standard |
Developer Resources Required | Significant legal & eng. overhead | Minimal (focus on core product) |
Estimated Annual Cost (1000 entities) | $50K - $150K+ | $20K - $50K |
Regulatory Future-Proofing | Low (rule changes break flows) | High (ZK logic is adaptable) |

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications by expert Solidity engineers.
We architect and deploy production-grade smart contracts for ERC-20, ERC-721, ERC-1155, and custom protocols. Our process delivers secure, gas-optimized code from day one, reducing audit costs and deployment risks.
- End-to-end development: From specification and architecture to deployment and verification.
- Security-first approach: Built with
OpenZeppelinstandards and internal audits before external review. - Multi-chain ready: Deployable on Ethereum, Polygon, Arbitrum, Base, and other EVM-compatible chains.
We don't just write code; we engineer systems that are secure, maintainable, and ready to scale.
Our engineers specialize in complex logic for DeFi (DEXs, lending/borrowing), NFTs (dynamic metadata, staking), and enterprise applications. We provide comprehensive documentation and a 2-week MVP sprint to validate your core concept.

Frequently Asked Questions
Get clear answers about our zero-knowledge KYB implementation, process, and security.
ZK-KYB (Zero-Knowledge Know Your Business) uses cryptographic proofs to verify a business's legitimacy without exposing its sensitive data. Unlike traditional KYB, which requires sharing full documents and PII with a central verifier, ZK-KYB allows a business to prove compliance (e.g., legal registration, good standing) to a counterparty using a verifiable credential. The counterparty only receives a cryptographic proof of validity, protecting business privacy and reducing data breach risk. We implement this using zk-SNARKs and W3C Verifiable Credentials.
