PROVEN METHODOLOGY
Our Development & Integration Process
A streamlined, security-first approach to deliver production-ready streaming data adapters. We focus on rapid deployment and long-term reliability, ensuring your team can build on a solid data foundation.
01
Discovery & Architecture Design
We analyze your specific data needs—from real-time wallet tracking to on-chain event triggers—and design a scalable adapter architecture. This includes selecting the optimal data sources (RPC nodes, indexers) and defining the final output format for your application.

Requirement Alignment
02
Secure Adapter Development
Our engineers build robust adapters using battle-tested libraries for EVM (Ethers.js, Viem) and Solana (web3.js, @solana/web3.js). Every component follows security-first patterns, including rate limiting, error handling, and data validation to prevent downstream failures.

Frequently Asked Questions
Common questions from CTOs and engineering leads about implementing real-time blockchain data infrastructure.
Standard deployments for a single-chain adapter (EVM or Solana) take 2-4 weeks from kickoff to production. Multi-chain integrations or complex event filtering can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial technical scoping session.
