Question 1

In ERC-1155, what does a single contract allow you to manage?

ERC-1155 is a multi-token standard that lets one contract manage many token types, both fungible and non-fungible.

Question 2

Which function signature is unique to ERC-1155 for moving several token types at once?

Accepted Answer

safeBatchTransferFrom

Answer

safeBatchTransferFrom lets ERC-1155 move multiple token IDs and amounts in a single transaction.

Question 3

What does ERC-721's ownerOf(tokenId) return?

Accepted Answer

The address that owns the specific token

Answer

ownerOf returns the single address that owns the given unique token ID.

Question 4

Why does ERC-1155 typically save gas when minting many items?

Accepted Answer

It batches operations and shares one contract for all token types

Answer

Batching and a shared contract reduce per-token deployment and transaction overhead.

Question 5

In ERC-1155, how is a fungible token represented versus a non-fungible one?

Accepted Answer

By a token ID with a supply greater than one (fungible) or exactly one (NFT)

Answer

A token ID with supply >1 behaves fungibly, while supply of 1 makes it effectively non-fungible.
