The Infrastructure Decision
Build vs. Buy: Tax Aggregation for Institutions
A detailed comparison of the time, cost, and risk involved in developing a cross-chain tax aggregation system in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore API |
|---|---|---|
Time to Production | 6-12+ months | 2-4 weeks |
Initial Development Cost | $250K - $500K+ | $0 (API subscription) |
Covered Chains & Protocols | Manual integration per chain | 30+ chains, 500+ DeFi protocols |
Security & Audit Burden | High (your responsibility) | Enterprise-grade, audited, SOC 2 compliant |
Regulatory Reporting Formats | Custom build for each jurisdiction | FIFO, LIFO, HIFO; IRS Form 8949, ATO, HMRC ready |
Ongoing Maintenance & Updates | Dedicated 3-5 person team | Fully managed, zero overhead |
Real-time Portfolio Sync | Complex to build and scale | Sub-5 minute latency, automatic |
Total Cost of Ownership (Year 1) | $500K - $1M+ | Starting at $60K/year |
Implementation Risk | High (project delays, bugs) | Low (proven platform, SLA-backed) |
