FREE NFT Development ERC-721 vs. ERC-1155 Standards Questions and Answers

Question 1

A blockchain-based game developer needs to create multiple in-game assets.
Some assets are unique, like a legendary sword (NFT), while others are stackable, like health potions (fungible tokens).
Which token standard is most suitable for this scenario and why?

Accepted Answer

ERC-1155, because it supports both fungible and non-fungible tokens within a single smart contract.

Answer

ERC-721, because it is the most established standard for all types of game assets.

Answer

ERC-721, because it allows for more detailed metadata for each unique item.

Answer

ERC-1155, because it is exclusively designed for fungible tokens, which are more common in games.

Question 2

When considering gas efficiency for minting a large number of NFTs for a new collection, which of the following statements is most accurate?

Accepted Answer

ERC-1155 is significantly more gas-efficient because it supports batch minting and transfers in a single transaction.

Answer

ERC-721 is more gas-efficient due to its simpler contract structure.

Answer

Both standards have identical gas costs for minting operations.

Answer

Gas efficiency is determined by network congestion, not the token standard.

Question 3

A digital artist wants to release a series of 100 unique, one-of-a-kind art pieces. Each piece has distinct metadata and is intended to be a standalone collectible. Which token standard is the most conventional and straightforward choice for this use case?

Accepted Answer

ERC-721, because it was specifically designed for truly unique, non-fungible assets, with each token having a distinct ID and metadata URI.

Answer

ERC-1155, because it allows for creating an edition of 100 tokens under a single ID.

Answer

ERC-1155, as it offers better compatibility with decentralized exchanges (DEXs).

Answer

Either standard would be equally suitable with no significant tradeoffs.

Question 4

Which feature is a key differentiator of the ERC-1155 standard compared to ERC-721?

Accepted Answer

Support for semi-fungible tokens.

Answer

The ability to assign a unique metadata URI to each token ID.

Answer

The requirement for each token to have a globally unique owner.

Answer

The `ownerOf(tokenId)` function to check token ownership.

Question 5

A developer is migrating a project from ERC-721 to ERC-1155 to save on transaction costs. What is the primary architectural change they will leverage in the ERC-1155 standard to achieve this?

Accepted Answer

Utilizing the `safeBatchTransferFrom` function to transfer multiple token types in a single transaction.

Answer

Deploying a separate smart contract for each token type.

Answer

Implementing a more complex metadata JSON structure.

Answer

Removing the approval mechanism to reduce function calls.

Question 6

In an ERC-1155 contract, what is the relationship between a `tokenId` and its metadata URI?

Accepted Answer

All tokens sharing the same `tokenId` also share the same metadata URI.

Answer

Each individual token has a unique metadata URI, even if they share the same `tokenId`.

Answer

All tokens within the contract share a single, global metadata URI.

Answer

Metadata is stored directly on-chain and does not use a URI.
