Strategic Infrastructure Decision
Build vs. Buy: Custom Protocol vs. Generic SDK
A detailed comparison of the time, cost, and risk involved in developing a custom EVM-to-Non-EVM bridge from scratch versus leveraging Chainscore's specialized protocol design service.
| Key Factor | Build In-House | Generic SDK | Chainscore Custom Protocol |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K | $100K - $300K |
Security Posture | High Risk (unaudited, novel code) | Medium Risk (audited, but generic) | Low Risk (bespoke, formally verified) |
Custom Logic & Features | Fully Customizable | Limited by SDK design | Tailored to your use case |
Cross-Chain Finality | You design it (high complexity) | Defined by SDK (< 5 min typical) | Optimized for your chains (< 2 min target) |
Ongoing Maintenance Burden | Full team required | Partial (SDK updates, integrations) | Optional SLA with 24/7 monitoring |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $100K - $250K | $150K - $400K |
Protocol Revenue Optimization | Built from zero | Limited fee model options | Custom fee logic & tokenomics |
Audit & Formal Verification | Additional $50K - $150K | Included (for SDK only) | Included (full custom protocol) |

STRUCTURED DELIVERY
Our EVM-to-Non-EVM Bridge Protocol Design Process
A systematic, security-first approach to architecting and deploying cross-chain bridges that move assets, not just data. We deliver production-ready protocols with audited security and measurable performance.
01
Architecture & Consensus Design
We design the core bridge architecture—choosing between optimistic, light client, or MPC-based models—and define the validator/multi-sig consensus mechanism for your target chains (e.g., Solana, Cosmos, Aptos).
