ENGINEERED FOR PERFORMANCE
Why Mobile-First Web3 SDKs Matter
Generic RPC clients fail on mobile. Our SDKs are built from the ground up for the constraints of mobile devices, delivering a native-grade user experience that drives adoption and retention.
Infrastructure Decision Matrix
Build vs. Buy: Custom Mobile RPC & Indexing SDK
A technical and financial comparison of developing a mobile-first RPC and indexing library in-house versus leveraging Chainscore's production-ready solution.
| Critical Factor | Build In-House | Chainscore SDK |
|---|---|---|
Time to Production-Ready SDK | 6-9 months | 2-4 weeks |
Initial Development Cost | $150K - $300K+ | $25K - $75K |
Annual Maintenance & DevOps | $80K - $150K | Included (Optional SLA) |
Multi-Chain Support (EVM, Solana, etc.) | Per-chain integration required | Pre-built, unified API |
Real-time Event Indexing & WebSockets | Complex backend service build | Out-of-the-box with <1s latency |
Mobile-Optimized Caching & State Sync | Custom implementation | Built-in with configurable TTL |
Security & Audit Overhead | High (Unaudited custom code) | Low (Audited core, enterprise SLAs) |
Team Expertise Required | Senior Rust/Go + Mobile + DevOps | Your existing mobile team |
Scalability to 100k+ MAU | Significant re-architecture | Handled by our global infrastructure |
Guaranteed Uptime SLA | Your responsibility (costly) | 99.9% with 24/7 monitoring |

PROVEN METHODOLOGY
Our Development & Delivery Process
A structured, transparent approach designed to deliver production-ready mobile RPC and indexing libraries with speed, security, and scalability.
01
Discovery & Architecture
We begin with a deep technical assessment of your use case, target chains, and performance requirements. We define the API spec, data indexing strategy, and architecture for your mobile-first environment.

Frequently Asked Questions
Common questions from CTOs and engineering leads evaluating our mobile-first blockchain infrastructure libraries.
For a standard integration with a single chain (e.g., Ethereum or Solana), we deliver a production-ready SDK in 2-3 weeks. This includes integration support, configuration for your specific use case, and initial load testing. Multi-chain support or complex custom indexing logic can extend this to 4-6 weeks.
