## Definition

ERC-1155 is a more flexible token standard that can hold many different token IDs in a single contract, with each ID supporting either one or many copies. It is widely used in games, where one contract might hold both unique items and stacks of consumable resources.

The single-contract design saves gas and simplifies large collections, while still allowing per-item ownership tracking.
