What Problem Did the ERC-1155 Standard Aim to Solve?
ERC-1155, the Multi-Token Standard, aimed to solve the inefficiency of managing multiple token types (both fungible and non-fungible) by requiring a separate contract for each. It allows a single smart contract to manage any number of fungible, non-fungible, or semi-fungible tokens.
This drastically reduces deployment costs and transaction fees (gas), and streamlines batch transfers of different token types.
