ERC-1155 Multi-Token Standard
Learn the ERC-1155 multi-token standard that lets a single contract manage fungible, semi-fungible, and non-fungible tokens together for gas-efficient batch operations.
Why ERC-1155 Exists
ERC-20 manages one fungible token; ERC-721 manages unique NFTs. But a game may need thousands of item types mixing both. Deploying a separate contract per type is wasteful.
ERC-1155 is a single contract that can manage many token IDs at once, each of which can be fungible or non-fungible.
Token IDs as Categories
In ERC-1155 each token is identified by a numeric id. The same id can have a balance greater than one (fungible) or a supply of exactly one (non-fungible).
id = 1with balance 500 = a fungible gold coinid = 2with balance 1 = a unique sword NFT
