A PROVEN FRAMEWORK
Our Methodology: From Audit to Execution
Our systematic approach minimizes risk and ensures a seamless transition for your protocol's major upgrade. We deliver predictable outcomes, not just tools.
01
Comprehensive State Analysis
We perform a deep audit of your current smart contract state, mapping all storage variables, user balances, and dependencies. This creates a complete, versioned snapshot that serves as the single source of truth for migration planning.

Risk-Mitigated Migration Design
We architect the migration path with built-in safety nets: multi-sig controlled upgrade triggers, phased rollouts, and comprehensive rollback procedures. Every step is designed to protect user funds and protocol integrity.

03
Custom Tool Development & Testing
We build bespoke migration scripts and verification tools tailored to your protocol's architecture. Each tool undergoes rigorous unit, integration, and fork-testing on a mirrored mainnet environment.

State Migration Tooling: Key Questions
Technical leaders evaluating state migration partners need clear answers. Here are the most common questions we receive from FinTech and Web3 teams planning major upgrades.
A standard state migration for a major protocol upgrade (e.g., token contract, governance system) is delivered in 2-4 weeks. This includes planning, custom tool development, dry-run testing, and mainnet execution. Complex migrations involving multiple contracts or custom logic can extend to 6-8 weeks. We provide a detailed project plan within 48 hours of scoping.
