NFT Development Advanced NFT Mechanics Questions and Answers

Question 1

A developer is creating a blockchain game where a primary character NFT needs to be able to own and equip other NFTs, such as swords and armor.
Which EIP provides a standardized interface for creating these explicit on-chain parent-child relationships?

Accepted Answer

EIP-6150 (Hierarchical NFTs)

Answer

EIP-2981 (NFT Royalty Standard)

Answer

EIP-5192 (Minimal Soulbound Tokens)

Answer

EIP-1155 (Multi Token Standard)

Question 2

Which of the following best describes the core mechanic and intended purpose of a Soulbound Token (SBT) as proposed in standards like EIP-5192?

Accepted Answer

It is permanently bound to a single account and cannot be transferred.

Answer

It can be fractionally owned by multiple wallets through ERC-20 tokens.

Answer

It bundles multiple fungible and non-fungible tokens into a single token ID.

Answer

It allows an NFT's metadata to be dynamically updated by a trusted oracle.

Question 3

An NFT holder keeps a valuable 'blue chip' NFT in a secure cold wallet but wants to use a separate, low-fund 'hot' wallet to mint a new token for which they are eligible. Which mechanism allows the hot wallet to act on behalf of the cold wallet without transferring the valuable asset?

Accepted Answer

Using a delegation registry like delegate.cash.

Answer

Wrapping the NFT into a wNFT contract.

Answer

Fractionalizing the NFT and sending a share to the hot wallet.

Answer

Implementing the EIP-2981 royalty standard on the minting contract.

Question 4

What is a primary advantage of generating an NFT's image directly on-chain as an SVG within the smart contract, compared to linking to an image stored on IPFS?

Accepted Answer

It ensures the image's permanence is tied directly to the blockchain's own lifespan.

Answer

It significantly reduces the gas cost of the minting transaction.

Answer

It allows for much more complex and high-resolution image data.

Answer

It simplifies the process of updating the image after the NFT has been minted.

Question 5

A developer is creating a dynamic NFT whose appearance changes based on the real-world price of Ethereum. What is the most critical component for securely and reliably feeding this external price data to the smart contract?

Accepted Answer

A decentralized oracle network like Chainlink.

Answer

A private backend server that calls a centralized exchange API.

Answer

A function that allows the token owner to manually input the current price.

Answer

Storing the image files on a high-availability centralized server.

Question 6

Which of the following accurately describes the typical technical process of NFT fractionalization?

Accepted Answer

The NFT is locked in a smart contract vault, which then mints fungible (e.g., ERC-20) tokens representing ownership shares.

Answer

The NFT's smart contract is upgraded to allow multiple owners in its internal mappings.

Answer

The NFT is burned, and a new EIP-1155 contract is deployed with a supply equal to the fractions.

Answer

The NFT's tokenURI is updated to point to a JSON file listing all fractional owners' wallet addresses.
