We treat this upgrade as an engineering program: architecture mapping, full state extraction, dual-run environments, behavioural diffing, and controlled cutover with reproducible proofs. You don’t replace your system, you step into the next version of your chain, aligned with Ethereum’s roadmap. The result? Bespoke infra → standardized EVM Isolation → optional interoperability Manual ops → predictable upgrades Privacy by isolation → privacy via ZK Low-trust → cryptographically assured
