The Strategic Choice for Your dApp's Longevity
Maintenance Service vs. In-House or Ad-Hoc Support
A direct comparison of approaches to managing your dApp frontend's ongoing health, security, and performance.
| Key Factor | In-House Team | Ad-Hoc Freelancer | Chainscore Managed Service |
|---|---|---|---|
Time to Resolution for Critical Bugs | Dependent on sprint cycles | Unpredictable availability | Guaranteed < 4 business hours |
Proactive Security & Dependency Updates | Manual, often delayed | Reactive only | Automated monitoring & weekly patches |
Framework & Library Upgrade Path | Major version upgrades require project re-scoping | Limited to minor patches | Planned, tested migration roadmap |
Performance & Core Web Vitals Optimization | Ad-hoc, expertise-dependent | Rarely included | Quarterly audits with actionable reports |
Cost Predictability (Annual) | High ($150K-$300K+ for Sr. Dev) | Variable, often spikes ($80K-$120K) | Fixed, transparent retainer ($60K-$120K) |
Protocol & Wallet Integration Updates | Your team must learn new specs | May lack latest API knowledge | Guaranteed updates within 48h of release |
Incident Response & 24/7 Monitoring | On-call burden on your team | Not available | Included with 99.9% uptime SLA |
Knowledge Continuity & Documentation | Risk of tribal knowledge | Scattered across messages/files | Centralized, versioned runbooks |
