Cross-Chain Market Data Aggregation

We build the unified, normalized data layer that ingests and processes market and event data from multiple blockchains, serving as the foundation for your multi-chain predictive models and trading strategies.

overview
CORE INFRASTRUCTURE

Blockchain Infrastructure Development

Build and scale robust, secure blockchain foundations for your Web3 product.

We architect and implement the foundational infrastructure that powers your application, from custom RPC nodes to secure key management systems. Our focus is on performance, reliability, and security from day one.

  • Custom Node Infrastructure: Deploy and manage dedicated EVM (Ethereum, Polygon, Arbitrum) and Solana RPC nodes with 99.9% uptime SLAs.
  • Secure Key & Wallet Management: Implement enterprise-grade solutions for key generation, storage, and transaction signing using AWS KMS, Hashicorp Vault, or MPC technology.
  • Indexing & Data Pipelines: Build real-time data pipelines for on-chain events, enabling fast queries and analytics without relying on centralized providers.

We deliver production-ready infrastructure in 2-4 weeks, allowing your team to focus on core product logic instead of DevOps.

Our development follows security-first principles, incorporating automated monitoring, alerting, and disaster recovery plans. We ensure your infrastructure can handle from 1,000 to 1M+ daily transactions without redesign.

A REPEATABLE, TRANSPARENT PROCESS

Our Methodology: From Discovery to Data Delivery

We follow a structured, four-phase engagement model designed to deliver production-ready, high-fidelity cross-chain data feeds. This ensures predictable timelines, clear deliverables, and zero surprises.

01

Phase 1: Discovery & Architecture

We conduct a technical deep-dive to map your specific data needs across EVM, Solana, and Cosmos chains. We define the optimal aggregation strategy, data sources, and delivery format (API, WebSocket, Indexer).

Technical & Commercial Considerations

Cross-Chain Data Aggregation: Key Questions

Common questions from CTOs and product leads evaluating cross-chain data infrastructure. Our answers are based on delivering 30+ aggregation systems handling $2B+ in daily volume.

Standard deployment is 3-5 weeks from kickoff to production-ready API. This includes:

  • Week 1-2: Architecture design, source selection (on-chain vs. off-chain), and smart contract deployment for data verification.
  • Week 3-4: Core aggregation engine development, indexer setup, and API layer construction.
  • Week 5: Integration testing, load testing, and final deployment to your environment.

Complex multi-protocol systems (e.g., aggregating 10+ DEXs across 5+ chains) may extend to 8 weeks. We provide a fixed-scope timeline after the initial technical discovery call.
