Strategic Infrastructure Decision
Build vs. Buy: Custom Bridge vs. Generic Solutions
A detailed comparison of developing a custom EVM-to-Non-EVM bridge in-house versus partnering with Chainscore Labs for a tailored, secure, and production-ready solution.
| Key Factor | Build In-House | Generic Third-Party Bridge | Chainscore Custom Bridge |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $0 - $50K (integration) | $80K - $250K |
Architecture Flexibility | Full control | Limited to provider's design | Tailored to your use case |
Security Posture | High risk (unaudited, new code) | Shared risk (public audits) | Enterprise-grade (dedicated audits) |
Protocol-Specific Logic | Your team builds it | Not supported | Built-in (e.g., Cosmos IBC, Solana CPI) |
Ongoing Maintenance Burden | Full team required | Managed by provider | Optional SLA with 24/7 monitoring |
Cross-Chain Messaging | Custom implementation | Generic token transfers | Custom data & asset logic |
Total Cost of Ownership (Year 1) | $300K - $600K+ | $20K - $100K+ (fees) | $100K - $300K (all-inclusive) |
Time to First Vulnerability | Unknown (your risk) | Public (shared risk) | Mitigated via formal verification |

Our Delivery Methodology
A structured, phased approach to bridge development that de-risks your project, accelerates time-to-market, and ensures enterprise-grade security from day one.
01
Architecture & Design Sprint
We begin with a collaborative 2-week sprint to define the optimal bridge architecture (e.g., optimistic vs. light client), token standards (e.g., ERC-20, SPL), and finalize the security model for your specific EVM and non-EVM chains.

Frequently Asked Questions
Get clear answers on timelines, costs, security, and our development process for building secure cross-chain bridges.
For a standard EVM-to-Non-EVM bridge (e.g., Ethereum to Solana, Avalanche to Cosmos), we deliver a production-ready, audited solution in 6-10 weeks. This includes design, core development, integration testing, security audit coordination, and deployment. Complex multi-chain or custom consensus bridges may extend to 12-14 weeks. We provide a detailed sprint-by-sprint roadmap at project kickoff.
