ERC-1155
ERC1155 is a novel token standard that aims to take the best from previous standards to create a fungibility-agnostic and gas-efficient token contract.
Extensions
Additionally, there are multiple custom extensions, including:
-
ERC-1155 Burnable: Optional Burnable extension of the ERC-1155 standard.
-
ERC-1155 Metadata URI: Optional extension that adds a token metadata URI.
-
ERC-1155 Pausable: A primitive to pause contract operation like token transfers, minting and burning.
-
ERC-1155 URI Storage: A more flexible but more expensive way of storing URI metadata.
-
ERC-1155 Supply: Extension of the ERC-1155 standard that adds tracking of total supply per token id.
