Description: Upgradable contracts are smart contracts that can be modified or updated after deployment to enhance functionality or address issues. Unlike traditional smart contracts, which are immutable once deployed on the blockchain, upgradable contracts allow developers to make changes to the code, which can be crucial for adapting to new needs or correcting errors. This feature is achieved through specific design patterns, such as the use of proxies, which redirect calls to the contract logic to an updated implementation. Upgradable contracts are particularly relevant in various technological domains, including the decentralized finance (DeFi) space, where speed and adaptability are essential to respond to a constantly changing environment. However, they also pose challenges in terms of security and trust, as the ability to update can be exploited if not implemented properly. Therefore, it is crucial for developers to follow rigorous security practices and maintain transparency with users regarding any changes made to the contract.
