Can smart contracts be changed after they are deployed?
Generally, smart contracts are immutable once deployed on the blockchain. However, there are ways to implement upgradability.
What does upgradability mean in the context of smart contracts?
Upgradability allows developers to modify the contract's logic or features without losing the existing data or state.
How can a smart contract be made upgradable?
One common method is using a proxy pattern, where the contract delegates calls to another contract that can be updated.
Are there any risks associated with upgradable smart contracts?
Yes, upgradable contracts can introduce security vulnerabilities if not implemented carefully, as they can be exploited.
