ERC-1155
ERC-1155 is an Ethereum token standard that enables the creation of both fungible (like ERC-20) and non-fungible (like ERC-721) tokens within a single smart contract. It improves efficiency by allowing batch transfers of multiple token types in one transaction, reducing gas costs and simplifying contract management. This standard is widely used in gaming, digital collectibles, and multi-token ecosystems on the Ethereum blockchain.
Developers should learn ERC-1155 when building applications that require multiple token types, such as video games with in-game items (e.g., currencies and unique assets) or platforms handling diverse digital assets. It's particularly valuable for reducing transaction costs and complexity in projects where users need to manage or trade various tokens simultaneously, making it a go-to standard for NFT marketplaces and blockchain-based gaming.
