Why Upgradeable Contracts?

Understand the necessity of upgradeability in smart contracts for bug fixes, feature enhancements, and long-term project viability.

Smart Contracts: Immutability

Smart contracts are programs stored on a blockchain that run when predetermined conditions are met. They are known for their immutability – meaning once deployed, their code cannot be changed.

This immutability is a core security feature, ensuring that rules cannot be altered after an agreement is made.

Immutability's Challenge

While immutability offers trust and security, it presents a significant challenge for ongoing development.

Think of it like carving a design into stone – it's permanent, but if you find a mistake or want to add something new, it's incredibly difficult or impossible.
