PROVEN METHODOLOGY
Our Phased, Risk-Managed Delivery Process
We mitigate the inherent risks of on-chain upgrades with a structured, transparent approach that ensures security, stability, and zero downtime for your users.
01
Phase 1: Architecture & Strategy
We analyze your existing system and design a tailored upgrade strategy. This includes selecting the optimal upgrade pattern (Transparent Proxy, UUPS, Diamond) and creating a comprehensive risk assessment and rollback plan.
48-72 hrs
Strategy Finalization
3+ Patterns

Phase 2: Development & Internal Testing
Our engineers implement the upgrade logic in Solidity 0.8+, utilizing OpenZeppelin libraries. Every line of new and modified code undergoes rigorous unit and integration testing in a forked mainnet environment.

Phase 4: Phased Mainnet Deployment
We execute the upgrade using a phased canary rollout. This starts with a limited user group, monitors on-chain metrics and off-chain logs, and only proceeds to full deployment after confirming 100% stability.
