PROVEN PROCESS
Our Migration Methodology
A structured, four-phase approach designed to migrate your legacy event feeds to a modern, scalable blockchain architecture with zero data loss and minimal operational disruption.
01
Discovery & Architecture Design
We conduct a comprehensive audit of your existing systems to map data flows, dependencies, and business logic. This phase delivers a detailed technical specification and target architecture blueprint for the new on-chain event feed.
