Inability to Upgrade Smart Contracts

Description: Once deployed, smart contracts are immutable, preventing updates or fixes after bugs are discovered.
Cause: Lack of upgradable contract design, limiting flexibility in fixing bugs or adding new features.
Solution: Implement proxy patterns for upgradable smart contracts, allowing for future modifications without altering the contract's address.

contract Proxy {
    address public implementation;

    function upgradeTo(address newImplementation) public {
        implementation = newImplementation;
    }

    function delegateCall(bytes memory data) public {
        (bool success, ) = implementation.delegatecall(data);
        require(success, "Delegatecall failed");
    }
}
