Advanced Batch Operations
The ERC11155 standard introduced batch technology to Ethereum. However, with that standard, only tokens of the same Collection can be used in batch operations.
The Item standard unleashes the full potential of batching by allowing all existing Items, both Native and Wrapped, even those of different Collections, to be used together in batch operations. This allows developers to design their DApps with more complex logic, and saves users gas when swapping or transferring several tokens at once.
Given that all ERC20s, ERC721s, ERC1155s and ETH can be wrapped as Items, this means that theoretically all tokens on Ethereum (of those standards) could be batched together, all at once, in a single transaction.
