Strategic Infrastructure Decision
Build vs. Buy: Custom Router vs. Generic Bridge
A technical and economic comparison of developing a custom EVM cross-chain router in-house versus using a generic third-party bridge versus partnering with Chainscore for a custom solution.
| Key Factor | Build In-House | Generic Bridge (e.g., Axelar, LayerZero) | Chainscore Custom Router |
|---|---|---|---|
Time to Market | 6-12 months | 1-2 weeks (integration) | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $0 - $50K (integration) | $50K - $150K |
Protocol & Chain Flexibility | Full control | Limited to provider's roadmap | Tailored to your roadmap |
Security Posture | Your responsibility (High risk) | Shared risk (Audited, but shared attack surface) | Dedicated, audited codebase (Low risk) |
Gas Optimization & Fee Logic | Custom, can be highly optimized | Fixed, one-size-fits-all | Custom algorithms for your users |
Ongoing Maintenance & Upgrades | Full-stack DevOps team required | Managed by provider | Optional SLA with 24/7 monitoring |
Branding & User Experience | Fully branded, seamless flow | Provider branding, disjointed UX | White-label, seamless flow |
Revenue Model Control | Keep 100% of fees/MEV | Share revenue with provider | Keep 100% of fees/MEV |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $10K - $200K+ (fees + revenue share) | $75K - $200K |

Frequently Asked Questions
Get clear answers on timelines, costs, security, and process for building a custom cross-chain router.
A production-ready EVM cross-chain router with core bridging functionality typically deploys in 4-6 weeks. Complex features like MEV protection, multi-asset support, or custom governance can extend this to 8-12 weeks. We follow a phased delivery model: Week 1-2 for architecture & design, Week 3-5 for core development and internal testing, and the final week for deployment and handover.
