What is the main advantage of using a Proxy contract over a traditional smart contract?

a: It can execute transactions faster than traditional smart contracts. Explanation

Explanation

b: It allows upgrading contract logic without changing the contract address. Explanation

Explanation

c: It stores more data than a traditional smart contract. Explanation

Explanation

d: It automatically secures the contract from all vulnerabilities. Explanation

Explanation

Which feature separates a Proxy contract from a traditional smart contract?

a: It combines both interface and implementation in one contract. Explanation

Explanation

b: It separates the interface from the implementation, allowing independent upgrades. Explanation

Explanation

c: It stores all user data off-chain. Explanation

Explanation

d: It requires redeployment for every logic change. Explanation

Explanation

Which of the following is a type of Proxy contract?

a: Transparent Proxy Explanation

Explanation

b: Hybrid Proxy Explanation

Explanation

c: Upgradeable Proxy Explanation

Explanation

d: All of the above Explanation

Explanation

What is an Upgradeable Smart Contract (USC)?

a: A smart contract that automatically fixes bugs. Explanation

Explanation

b: A contract that can be updated without changing its address. Explanation

Explanation

c: A contract that stores all logic off-chain. Explanation

Explanation

d: A traditional immutable smart contract. Explanation

Explanation

Why might a Proxy contract improve security?

a: It encrypts all transactions automatically. Explanation

Explanation

b: It adds a layer between users and the logic contract, making exploitation harder. Explanation

Explanation

c: It prevents users from interacting with the contract directly. Explanation

Explanation

d: It stores user private keys safely. Explanation

Explanation

What is a drawback of the data-separation pattern in Upgradeable Smart Contracts?

a: It prevents upgrades entirely. Explanation

Explanation

b: Constant calls between logic and storage increase gas costs. Explanation

Explanation

c: It merges logic and storage, reducing modularity. Explanation

Explanation

d: It automatically redeploys contracts for each update. Explanation
