METHODICAL & TRANSPARENT
Our Process: From Fork to Final Report
Our structured, four-phase methodology ensures your protocol upgrade is tested with production-grade rigor, providing the confidence needed for a seamless mainnet deployment.
01
1. Environment Forking & Setup
We create a deterministic fork of your target mainnet state, including all live contracts, token balances, and recent transaction history. This provides a true-to-life sandbox for testing.

2. Upgrade Simulation & Stress Testing
We deploy and execute your upgrade logic under extreme load and edge-case scenarios, simulating high gas prices, MEV bots, and adversarial user behavior to uncover hidden vulnerabilities.

Frequently Asked Questions
Get clear answers on how we deliver secure, production-ready blockchain upgrades through rigorous simulation and testing.
A comprehensive upgrade simulation and testing engagement typically takes 2-4 weeks from kickoff to final report. This includes environment setup, test suite development, execution of simulations (including edge cases and failure modes), and the delivery of a detailed audit report with actionable remediation steps. Complex protocol upgrades or multi-chain deployments may extend this timeline.
