Build vs. Buy: Privacy-Centric Cross-Chain
A detailed comparison of the costs, risks, and timelines associated with developing privacy-preserving cross-chain communication in-house versus leveraging Chainscore's production-ready platform.
| Factor | Build In-House | Chainscore Platform |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K |
Security Audit Overhead | High (unaudited, custom risk) | Low (pre-audited core, battle-tested) |
Core Protocol Expertise | Requires hiring specialists | Included (ZKPs, TEEs, MPC) |
Ongoing Maintenance & Upgrades | Full-time team (2-3 engineers) | Managed service with optional SLA |
Cross-Chain Support | Limited to initial build targets | Ethereum, Polygon, Arbitrum, Base, Scroll, more on request |
Privacy Leakage Risk | High (novel implementation) | Minimal (proven cryptographic primitives) |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $80K - $200K |

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deploying privacy-preserving cross-chain communication. We deliver production-ready infrastructure, not just prototypes.
01
Architecture & Protocol Design
We design your system's core architecture, selecting and customizing the optimal privacy-preserving protocol (e.g., zk-SNARKs, MPC, TEEs) for your specific cross-chain use case. This ensures a scalable, secure, and cost-effective foundation.

Smart Contract & ZK Circuit Development
Our team writes and audits the core logic: verifier contracts for zero-knowledge proofs, secure MPC coordination modules, and the message-passing bridges. Built with Solidity 0.8+ and frameworks like Circom or Halo2.
