A Strategic Comparison
Build vs. Buy: Cross-Chain Smart Contract Framework
Evaluating the total cost of ownership and technical risk between developing a cross-chain framework internally versus leveraging Chainscore's production-ready solution.
| Factor | Build In-House | Chainscore Framework |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited, battle-tested patterns) |
Ongoing Maintenance Burden | Full-time dedicated team | Optional SLA with 24/7 monitoring |
Multi-Chain Protocol Support | Requires custom integration per chain | Pre-built for Ethereum, Polygon, Arbitrum, Base, Optimism |
Cross-Chain Messaging (CCIP/ Axelar) | Complex, custom relayers required | Integrated, configurable adapter layer |
Disaster Recovery & Upgrades | Manual, high-risk processes | Managed rollouts with zero-downtime strategies |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $75K - $200K |

END-TO-END FRAMEWORK
Our Development & Audit Process
A rigorous, multi-phase methodology designed for security, scalability, and seamless cross-chain deployment. We deliver production-ready code, not just prototypes.
01
Architecture & Design Review
We begin with a deep technical assessment of your cross-chain logic, tokenomics, and integration points. This phase establishes a secure, gas-efficient blueprint using established patterns from protocols like Axelar and Wormhole.

Technical & Commercial Details
Cross-Chain Framework FAQs
Answers to the most common questions from CTOs and technical founders evaluating our cross-chain smart contract development services.
For a standard cross-chain application (e.g., a multi-chain DEX or lending protocol), we deliver a production-ready MVP in 4-6 weeks. This includes architecture design, smart contract development on 2-3 target chains, bridge integration, and initial security review. Complex protocols with custom bridging logic or novel consensus mechanisms can take 8-12 weeks. We provide a detailed sprint-by-sprint timeline after the initial technical scoping call.
