Upgradeable Contracts

Once deployed to a blockchain, smart contracts cannot be changed. This immutability is a core security feature, ensuring that rules can't be altered unexpectedly.

Think of it like carving rules into stone – they are fixed for all time, which builds trust and predictability in decentralized applications.

While immutability provides strong security, it also poses significant challenges for developers:

• Bug Fixes: What if a critical bug is found after deployment?
• Feature Updates: How do you add new functionalities or adapt to evolving standards?
• Data Migration: Without a plan, fixing issues means deploying a completely new contract and migrating all user data, which is often complex and expensive.
