Build a Hub vs. Per-Chain KYC Integration
A technical and economic comparison of developing a custom multi-chain KYC solution in-house versus leveraging Chainscore's managed verification hub.
| Integration Factor | Build In-House | Chainscore Hub |
|---|---|---|
Time to First Integration | 3-6 months | 2-4 weeks |
Supported Chains (Initial) | 1 chain | Ethereum, Polygon, Arbitrum, Base, Optimism |
Security Audit Scope & Cost | $50K-$150K + 8-12 weeks | Included (pre-audited) |
Ongoing Chain Expansion | 2-4 months per new chain | Enabled in < 2 weeks |
Compliance Rule Updates | Manual, developer-led | Managed, automatic updates |
Team Resources Required | 2-3 Sr. Devs + DevOps | 1 Dev for API integration |
First-Year Total Cost | $250K-$600K+ | $75K-$200K |
Uptime & Monitoring SLA | Your responsibility | 99.9% with 24/7 alerting |

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our development process is built on audited security patterns and gas optimization from day one.
- Full Lifecycle Delivery: From initial design and
Solidity/Rustdevelopment to deployment and on-chain verification. - Security-First: Contracts are built with
OpenZeppelinlibraries and undergo internal audits before client review. - Protocol Integration: Native support for
ERC-20,ERC-721,ERC-1155, and custom standards.
We deliver battle-tested contracts that power live protocols, ensuring reliability at scale and minimized attack surfaces.
Our engineers specialize in complex logic for automated market makers (AMMs), staking vaults, and cross-chain bridges. We provide comprehensive documentation and a 2-week MVP delivery for rapid iteration.

Frequently Asked Questions
Get clear answers on implementation, security, and integration for our enterprise-grade KYC verification solution.
Standard integration takes 2-4 weeks from kickoff to production deployment. This includes environment setup, smart contract deployment on your target chains (EVM, Solana, etc.), and API integration with your frontend. Complex custom rule-sets or novel chain support may extend this timeline, which we scope during the initial technical discovery phase.
