Varota is designed to generate evidence of storage compatibility for deployment reviews.
The purpose is to make upgrade verification more transparent, helping teams assess identified differences before deciding whether to proceed.
For development teams, documented findings also improve communication between engineers, auditors, and deployment reviewers.
Instead of relying only on informal checks, teams can use structured evidence to support more consistent upgrade decisions.
Trust in a smart contract upgrade should be supported by evidence, not assumptions.
Varota generates storage compatibility reports that help development teams review upgrade risks, document findings, and make more informed deployment decisions.
Reliable upgrades begin with clear evidence.
By comparing storage layouts before deployment, Varota helps development teams identify potential conflicts, investigate differences, and make better-informed decisions about whether an upgrade is ready to proceed.
The challenge is not simply whether the new contract compiles. It is whether the new implementation can safely read the state written by the previous one.
Varota focuses on this compatibility layer, where seemingly minor layout changes can have serious consequences.
A smart contract upgrade should never assume that storage remains compatible.
Even small changes in storage slot positions can put existing state at risk.
Varota compares storage layouts before upgrades, helping developers detect conflicts before they become costly problems.
Varota examines inherited storage structures as part of its compatibility-focused approach.
The goal is to help developers detect potentially destructive layout changes, understand the risks, and preserve the integrity of existing contract state throughout an upgrade.
A modification to a base contract can have consequences beyond the file being edited.
If the resulting storage layout differs from what the existing proxy state expects, the new implementation may interpret previously stored values incorrectly.
Smart contract upgrades can introduce risks long before deployment.
Inheritance changes may affect how storage is organized, creating conflicts that are easy to overlook.
Varota verifies inherited storage layouts to help identify potentially destructive changes before they reach production.
