ERC-1155
An Ethereum token standard that lets a single contract manage many token types at once, both fungible and unique.
ERC-20 handles fungible tokens; ERC-721 handles unique NFTs. Each needs its own contract. ERC-1155, introduced by the Enjin team, holds both in one. A single contract can track a stack of identical potions and a one-of-a-kind sword, each under its own ID.
The practical win is efficiency. Games and marketplaces that mint thousands of items save gas through batch transfers, moving many token types in one transaction instead of many. The standard dominates blockchain gaming and is common wherever a project issues large, mixed sets of items rather than a single collection.
