The Infrastructure Decision
DEX Development vs. Building In-House
A direct comparison of the time, cost, and risk involved in developing a high-performance DEX yourself versus partnering with Chainscore Labs.
| Development Factor | Build In-House | Chainscore DEX Development |
|---|---|---|
Time to Market | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $80K - $200K |
Core AMM & Router | Build from scratch | Pre-audited, modular codebase |
Security Audit Burden | Your responsibility (high risk) | Included (OWASP, ConsenSys patterns) |
Multi-Chain Deployment | Per-chain integration effort | Pre-configured for EVM L2s & L1s |
Liquidity Bootstrapping | Manual partner outreach | Integrated incentive & launchpad tools |
Ongoing Protocol Upgrades | Your engineering team | Optional upgrade & maintenance SLA |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $120K - $300K |

PREDICTABLE, SECURE, AND SCALABLE
Our Delivery Process: From Protocol Audit to Live Integration
We follow a rigorous, battle-tested methodology to deliver secure, production-ready identity verification systems. Our process ensures zero surprises, full transparency, and seamless integration into your existing infrastructure.
01
Phase 1: Protocol & Smart Contract Audit
We conduct a comprehensive security review of your existing identity protocol or smart contracts. Our audit identifies vulnerabilities, gas inefficiencies, and compliance gaps before development begins, ensuring a secure foundation.
Deliverables: Detailed audit report, vulnerability scoring, and remediation roadmap.

Phase 2: Architecture & Design
We design a scalable, modular architecture for your Proof-of-Stake (PoS) identity layer. This phase defines the integration points, data flows, and key components like verifiable credentials (VCs) and decentralized identifiers (DIDs) to meet your specific use case.
Deliverables: Technical specification document, system architecture diagrams, and integration plan.

Phase 3: Development & Security Hardening
Our engineers build the custom smart contracts, off-chain verifiers, and APIs using Solidity 0.8+ and OpenZeppelin libraries. Every component undergoes internal peer review and automated security testing throughout the development cycle.
Deliverables: Production-ready codebase, comprehensive test suite, and internal audit report.

Phase 4: Independent Security Audit
Before deployment, the entire system undergoes a formal audit by a leading third-party security firm. We manage the entire audit process, from firm selection to issue resolution, providing you with an industry-recognized seal of security.
Deliverables: Final audit report from a recognized firm and proof of all critical fixes.

Phase 5: Staging & Testnet Deployment
We deploy the complete system to a staging environment and public testnet (e.g., Sepolia, Holesky). This allows for full integration testing with your application, load testing, and final user acceptance testing (UAT) in a risk-free setting.
Deliverables: Live staging environment, testnet deployment, and performance benchmark report.

Technical & Commercial Insights
Frequently Asked Questions on POS DID Integration
Get clear, specific answers to the most common questions from CTOs and product leads evaluating Proof of Stake Decentralized Identity solutions.
A standard implementation takes 3-5 weeks from kickoff to mainnet deployment. This includes 1 week for architecture design, 2-3 weeks for core smart contract development and integration, and 1 week for security audit and final deployment. Complex integrations with existing KYC/AML systems or multi-chain support may extend this to 6-8 weeks.
