Enjin.com co-founder and CTOWitek Radomski issued a message on Medium yesterday that ERC-1155 has become a formal Ethereum token standard. It is reported that ERC-1155 allows developers to create and manage thousands of game tokens with one click. Many other applications can also benefit from this flexible token standard. This design can achieve new features, such as transferring multiple token types at a time, saving transaction costs. Multiple token transactions (managed/atomic exchange) can be built on top of this standard, eliminating the need to separately “approve” a single token contract.
