BAP-578 Contract Upgrade

To upgrade a smart contract without changing the proxy address, use the UUPS proxy pattern. This approach manages the upgrade process internally, ensuring backward compatibility and data integrity while maintaining the original address.

The UUPS proxy pattern is an upgrade mechanism where the upgrade logic resides within the implementation contract itself. It safely upgrades smart contracts to new versions without changing the proxy address, ensuring data integrity.

To maintain storage layout compatibility during a smart contract upgrade, follow storage layout discipline. This practice ensures backward compatibility and protects data integrity when developing V2 implementations.

You need a contract upgrade pattern when you want to add new features or fix bugs in a deployed smart contract. Using a UUPS proxy allows you to upgrade the implementation while keeping the same proxy address.

Yes, you can fix bugs without losing data by using the UUPS proxy pattern for your contract upgrade. This method ensures backward compatibility and data integrity while facilitating the development of new contract versions.

The UUPS proxy pattern requires strict storage layout discipline to ensure backward compatibility and data integrity. If the upgrade logic is flawed or storage variables are misaligned during V2 implementation, the contract upgrade may fail or corrupt data.
