Strategic Analysis
Build vs. Buy: The Compliance Bridge Decision
A detailed comparison of the total cost, risk, and resource commitment required to develop a secure, multi-chain compliance bridge in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore Labs |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $75K - $200K |
Security Audit & Pen Testing | External cost: $30K - $100K | Included in package |
Ongoing Maintenance & Upgrades | 2-3 FTEs ($200K+/year) | Optional SLA from $50K/year |
Cross-Chain Protocol Expertise | Must be hired/developed | Included (EVM, Cosmos, Solana) |
Regulatory Logic Modules | Custom build from scratch | Pre-audited, modular library |
Time-to-First-Audit | Months after development | Weeks (integrated process) |
Total Year 1 Cost (Est.) | $480K - $900K+ | $125K - $250K |
Key Risk Profile | High (unaudited, untested team) | Low (battle-tested, audited code) |

PREDICTABLE, SECURE, SCALABLE
Our Development & Integration Process
A structured, auditable approach to building your cross-chain compliance layer, designed for rapid deployment and enterprise-grade security.
01
Compliance Architecture Design
We architect your bridge's compliance logic—defining rule sets for sanctions screening, transaction limits, and jurisdictional policies—before a single line of code is written. This ensures regulatory requirements are engineered in from day one.
2-3 days
Design Sprint

Requirement Coverage
02
Smart Contract & Oracle Development
Development of the core bridge smart contracts and secure off-chain oracles that fetch and verify compliance data (e.g., sanctions lists). Built with Solidity 0.8+ and OpenZeppelin libraries, following modular security patterns.

Frequently Asked Questions
Get clear answers on development timelines, security, costs, and ongoing support for your cross-chain compliance solution.
A standard deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 2 weeks for architecture design and smart contract development, 1 week for internal security review and testing, and 1-3 weeks for client-side integration and final audits. Complex requirements like custom regulatory rule engines or support for >5 chains can extend the timeline.
