Solidity Upgrade Safety FAQs

Question 1

How does this skill help with storage layout?

Accepted Answer

It provides strict 'Always' and 'Never' rules, such as using storage gaps and adding new variables only at the end of the contract, along with commands to verify layouts using Foundry.

Question 2

Why should I use _disableInitializers() in the constructor?

Accepted Answer

This prevents an attacker from taking over the implementation contract directly, which is a critical security step for all logic contracts used behind proxies.

Question 3

Does it support OpenZeppelin standards?

Accepted Answer

Yes, the skill is built around best practices for OpenZeppelin upgradeable contracts, including the use of Initializable and UUPSUpgradeable modules.

Question 4

Can I use this for fork testing?

Accepted Answer

Yes, it includes specific code patterns for testing upgrades on local forks using Foundry to ensure state preservation before deploying to mainnet.

Question 5

What are the most common mistakes in Solidity upgrades?

Accepted Answer

The most common mistakes include storage collisions (reordering or deleting variables), leaving implementation contracts uninitialized, and accidentally removing authorization functions like _authorizeUpgrade in UUPS patterns.
