Web3 API Infrastructure

Introduction

Designed and deployed the core API layer for the Cosmos ecosystem — powering $50M+ daily volume and 10M+ requests/day with p99 <100 ms latency. Trusted by Osmosis, Xion, and Quasar for real-time market data and analytics. This architecture delivers sub-second access to live blockchain data with maximum availability and 5x cost efficiency over industry benchmarks.

The Challenge

Web3 protocols operate in markets demanding immediacy, resilience, and precision — where every second of delay or downtime means lost capital and trust. Osmosis, Xion, and Quasar (Tower) required sub-200 ms latency, fault tolerance, and stability under extreme traffic, while operating at 5x lower cost than existing solutions. This included aggregating prices from multiple DEXs, calculating precise financial metrics, and tracking liquidity depth across 3,000+ pools in real time.

Solution & Approach

Delivered an API infrastructure optimized for performance, reliability, and operating cost — sustainable, auditable, and extensible.

Real-Time Data Pipeline

• Processed 1,500+ blocks/min across 25 Cosmos chains with custom indexers
• Reduced error impact via event-driven pub/sub with DLQ handling
• Built historical pipelines in DBT with storage in BigQuery and ClickHouse
• Served <100 ms queries on 5TB+ of time-series data in ClickHouse cluster
• Maintained live-updated entities in PostgreSQL cluster
• Deployed multi-region on GCP and Cloudflare with automatic failover

Performance Optimization

• Cut endpoint costs and latency by 5x via smart caching
• Reduced database costs by 70% through SQL query optimization
• Implemented custom algorithms for pricing, APRs, and liquidity across 3,000+ pools
• Handled 100K+ requests/sec with DDoS protection and rate limiting

Technical Impact

• 99.99% uptime over 18 months
• 10M+ daily API requests with p99 latency <100 ms
• 500K+ daily active users across integrated protocols and tools
• Costs well below market average, increasing client margins
• Zero security incidents or breaches

Business Impact

• $50M+ daily volume supported through these endpoints
• Four major protocols migrated from competing infrastructures
• Ongoing API revenue growth from new clients and expansion within existing ones
• Gained institutional visitibility for the Cosmos ecosystem
• Integrated by TradingView, DexScreener, CoinMarketCap, CoinGecko, DefiLlama, and Token Terminal
• Partner SDK cut integration time from weeks to hours

Now scaling beyond 15M daily requests, this architecture powers real-time DeFi analytics for leading protocols at a fraction of industry cost — setting a new benchmark for Web3 data infrastructure.
