Upgradable Smart Contracts

Upgradable smart contracts are systems designed to allow developers to fix bugs or add features without migrating users to a completely new contract address. This is typically achieved through the use of proxy patterns, where the user interacts with a stable proxy that forwards requests to an upgradeable implementation contract.

This is crucial for financial protocols, as it allows for rapid responses to security threats or changing market conditions. However, it introduces significant trust assumptions and technical risks, as the ability to upgrade can be abused if not properly governed.

Balancing the need for agility with the immutability core to blockchain technology is a central theme in modern decentralized finance architecture.
