When should I choose a Beacon proxy over UUPS?

You should choose a Beacon proxy when you need to deploy and manage many instances of a contract simultaneously. It allows you to upgrade every instance at once by updating a single Beacon contract.

How does this skill help prevent storage collisions during upgrades?

The skill provides strict storage layout rules, such as never changing the order or types of existing variables and using storage gaps in base contracts to ensure that new implementation versions don't overwrite existing state.

Does this skill include security checklists for contract upgrades?

Yes, it integrates with security audit workflows and provides checklists for safe upgrade practices, ensuring critical functions like _authorizeUpgrade are correctly and securely implemented.

Which proxy pattern is recommended for most Solidity use cases?

UUPS (Universal Upgradeable Proxy Standard) is generally recommended because it is more gas-efficient than Transparent proxies and offers more flexible upgrade authorization logic directly within the implementation contract.

Provides expert guidance and implementation patterns for building upgradeable Ethereum smart contracts using UUPS, Transparent, and Beacon proxies.

소개

The Proxy Patterns skill serves as a comprehensive reference for developers implementing or auditing upgradeable smart contracts in Solidity. It guides users through selecting the optimal proxy architecture—ranging from gas-efficient UUPS to robust Transparent and Beacon patterns—while enforcing critical storage layout rules to prevent data corruption. This skill is essential for ensuring long-term maintainability and security in blockchain applications where contract immutability needs to be balanced with the ability to fix bugs and add features.
