Framing and Walls + Opening Doors

1. In the context of smart contract development, what does "inheritance" mean?
   1. Passing down digital assets to your descendants
   2. Using someone else's contract with their permission
   3. Extending the functionality of an existing contract (x)
2. In ERC-20 token context, which of the following are correct about the _mint function?
   1. It creates new tokens through the proof-of-stake consensus mechanism
   2. It creates new tokens and assigns them to the contract deployer (x)
   3. It maintains the token minting history for auditability
   4. It adds tokens to the total supply, increasing the overall token amount (x)

Lock the Door!

   2. Observer Pattern
   3. AccessControl Pattern (x)
   4. Decorator Pattern
2. What is the purpose of the modifier onlyRole(MINTER_ROLE) in the mint function?
   1. It ensures that only addresses with the MINTER_ROLE can call the mint function (x)
   2. It allows any address to call the mint function
   3. It sets the role of the address calling the mint function

Final touches/House inspection

1. Why is the .env file in the deployment process so significant?
   1. It contains the contract code
   2. It stores metadata about the contract
   3. It holds secrets, especially the private key (x)

Register your house

1. Why do we include the --verify modifier in the forge create command?
   1. To display a detailed output of the deployment (x)
   2. To enable optimizations in the Solidity compiler
   3. To verify the deployed contract on Etherscan (x)
