Our DID Integration & Migration Capabilities
We architect and execute secure, scalable migrations from legacy identity systems to modern, interoperable Decentralized Identity (DID) frameworks. Our focus is on minimizing business disruption while maximizing user control and compliance.
01
Legacy System Analysis & DID Strategy
We conduct a comprehensive audit of your existing identity infrastructure (OAuth, SAML, proprietary databases) to design a phased migration roadmap. This ensures a clear path to DID adoption with minimal operational risk.

Strategic Decision Analysis
DID Integration: Build In-House vs. Partner with Chainscore
A technical and financial comparison of developing decentralized identity infrastructure internally versus leveraging Chainscore's managed service.
| Integration Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $200K - $500K+ | $50K - $150K |
Annual Maintenance Cost | $100K - $250K (2-3 FTEs) | $25K - $75K (Managed SLA) |
Security & Audit Burden | High (Your team manages audits, key management, vulnerabilities) | Low (Pre-audited modules, SOC 2 Type II, managed security) |
Protocol Expertise Required | W3C DID, Verifiable Credentials, Ethereum/Polygon, IPFS | Provided by our team; your team focuses on core product |
Scalability & Upgrades | Your responsibility (node ops, gas optimization, protocol upgrades) | Handled by Chainscore (automatic scaling, zero-downtime upgrades) |
Compliance & Standards | Your team researches & implements (GDPR, travel rule, regional laws) | Built-in compliance frameworks and legal opinion partnerships |
Support & Incident Response | Internal on-call rotation, variable response times | 24/7 SRE team with <1 hour SLA for P1 issues |
Total Cost of Ownership (3 Years) | $500K - $1.25M+ | $125K - $300K |
