PROVEN PROCESS
Our Migration Methodology
Our structured, four-phase approach minimizes risk and downtime while ensuring a seamless, secure transition to your new data availability layer.
01
Discovery & Architecture Review
We conduct a comprehensive audit of your current stack, smart contracts, and data dependencies to build a detailed migration blueprint. This includes identifying critical state, analyzing cross-chain dependencies, and defining rollback procedures.

Technical & Commercial Questions
DA Layer Migration FAQs
Get clear answers on timelines, costs, and technical specifics for migrating your rollup's Data Availability layer.
A standard migration from a centralized sequencer or a rollup-as-a-service provider to a dedicated DA layer like Celestia, Avail, or EigenDA takes 2-4 weeks. This includes architecture review, smart contract adaptation, testing, and mainnet deployment. Complex protocols with custom fraud proofs or multi-chain dependencies may require 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
