Strategic Infrastructure Decision

Build vs. Buy: Custom DA Bridge vs. Generic Solutions

A detailed comparison of the total cost, risk, and time investment for developing a ZK-Rollup Data Availability (DA) bridge in-house versus partnering with Chainscore Labs for a custom, production-ready solution.

Key Factor	Build In-House	Generic Bridge SDK	Chainscore Custom DA Bridge
Time to Production	6-12+ months	2-4 months	4-8 weeks
Upfront Development Cost	$250K - $750K+	$50K - $150K	$100K - $300K
Core Security & Audits	Your responsibility (high risk)	Limited to SDK (medium risk)	Full-stack audit included (low risk)
Custom Logic & Features	Fully customizable	Constrained by SDK limits	Tailored to your rollup's needs
Ongoing Maintenance & Upgrades	Full internal team required	Dependent on SDK provider	Optional SLA with 24/7 support
Integration Complexity	Extreme (ZK circuits, consensus, DA)	Moderate (SDK integration)	Minimal (we handle full integration)
Multi-Chain DA Support	Custom development per chain	Limited predefined options	Designed for extensibility (Ethereum, Celestia, Avail, EigenDA)
Total Cost of Ownership (Year 1)	$400K - $1M+	$150K - $300K	$150K - $400K (predictable)
