Strategic Decision Analysis
Build vs. Buy: Off-Chain Attestation Integration
Compare the total cost, risk, and time commitment of developing an in-house attestation system versus partnering with Chainscore for a managed, enterprise-grade solution.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Annual Maintenance & Ops Cost | $80K - $200K | Included in SLA |
Security & Audit Overhead | High (Requires dedicated audit budget) | Low (Pre-audited, battle-tested framework) |
Team Expertise Required | Specialized Solidity, cryptography, and DevOps engineers | Your existing Web3 team + our specialists |
Protocol & Standard Support | Manual integration per chain/standard (EIP-712, EIP-191, etc.) | Multi-chain, multi-standard support out-of-the-box |
Scalability & Performance | Bottlenecks require re-architecture | Horizontally scalable with 99.9% uptime SLA |
Compliance & Legal Risk | Your full liability; complex regulatory mapping | Shared framework with built-in compliance patterns |
Integration Complexity | High (Custom API, key management, monitoring) | Low (Plug-and-play SDKs, comprehensive docs) |
Total Cost of Ownership (Year 1) | $230K - $600K+ | $50K - $150K |
