ERC721 vs ERC1155

ERC-1155 and ERC-721 are both Ethereum token standards, but they have different properties and uses:

ERC-1155 It's a multi-token standard that allows for the creation of both fungible (interchangeable) and non-fungible (unique) tokens within the same smart contract.

Some functions described below:

This allows for more flexibility and can result in reduced gas costs compared to using separate contracts for different types of tokens.

ERC-721 It's a non-fungible token standard that defines a minimum interface for unique, indivisible tokens on the Ethereum blockchain. This means each token has its own unique identity, attributes and ownership.

ERC-721 is most commonly used for creating unique digital assets such as collectible items, virtual real estate and more.
