What Specific Efficiency Improvements Does the ERC-1155 Standard Offer over ERC-20 for Large-Scale Token Operations?

ERC-1155, a multi-token standard, allows a single smart contract to manage both fungible and non-fungible tokens. Crucially, it enables batch transfers and batch approvals of multiple token types in a single transaction.

This drastically reduces the required transaction count and associated gas costs compared to the single-token, single-transaction limitations of ERC-20 and ERC-721.
