CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
- Custom Logic:
ERC-20,ERC-721,ERC-1155, DeFi primitives, DAO governance, and bespoke business rules. - Security Framework: Built with
OpenZeppelinlibraries, followingSolidity 0.8+best practices and formal verification patterns. - Full Lifecycle: From specification and development to testing, deployment, and post-launch monitoring on
EVM/L2networks.
Reduce your time-to-market and technical risk. We deliver battle-tested contracts with comprehensive documentation and a clear path to audit by firms like ConsenSys Diligence or Trail of Bits.

Technical & Operational Comparison
ZK KYC Gateway vs. Traditional Compliance Methods
A direct comparison of the key technical, operational, and cost factors between building a custom Zero-Knowledge KYC solution in-house versus partnering with Chainscore for a production-ready gateway.
| Factor | Build In-House | Chainscore ZK Gateway |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $75K - $200K |
Cryptographic Expertise Required | High (ZK-SNARKs/STARKs) | None (We provide) |
Security Audit & Compliance | Your responsibility (high risk) | Pre-audited, verifiable circuits (low risk) |
Ongoing Maintenance & Updates | Dedicated team required | Managed service with optional SLA |
User Privacy & Data Sovereignty | Complex to implement | Built-in (ZK proofs only) |
Integration Complexity | High (custom SDKs, wallets) | Low (modular API & SDK) |
Supported Jurisdictions & Rules | Manual, static updates | Dynamic, programmable policy engine |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $100K - $250K |

Frequently Asked Questions
Get clear, specific answers about our Zero-Knowledge KYC Gateway development process, timeline, and security.
A standard Zero-Knowledge KYC Gateway deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for requirements & architecture, 2-3 weeks for core development and integration, and 1 week for security review and deployment. Complex integrations (e.g., multi-chain support, custom credential schemas) may extend this by 1-2 weeks. We provide a detailed project plan with milestones at the start.
