PROVEN METHODOLOGY
Our End-to-End Migration Framework
A structured, four-phase process designed to migrate your legacy data feeds to decentralized oracles with zero downtime and full data integrity. We manage the entire lifecycle from assessment to post-launch support.
01
Discovery & Architecture Design
We conduct a comprehensive audit of your existing data sources, APIs, and integration points. Our team delivers a detailed migration blueprint, including oracle network selection (Chainlink, Pyth, API3), data schema mapping, and a phased rollout plan.

Technical & Commercial Questions
Legacy System Migration FAQs
Answers to the most common questions CTOs and engineering leads ask when evaluating a legacy system migration to blockchain oracles.
Our standard migration process takes 4-8 weeks from kickoff to mainnet deployment. This includes a 1-week discovery and architecture review, 2-4 weeks for core development and integration, 1 week for security audits and testing, and 1-2 weeks for deployment and monitoring setup. Complex multi-chain integrations or heavily customized logic can extend this to 12 weeks. We provide a detailed project plan with milestones during the initial assessment.
