What are ERC 1155?
ERC-1155 is a token standard for the Ethereum blockchain that was proposed by Enjin in 2018
It is a unique token standard that allows for the creation of both fungible and non-fungible tokens within the same contract, which provides significant benefits in terms of efficiency and flexibility
One of the main advantages of ERC-1155 is that it reduces the number of transactions required to manage multiple types of tokens
Traditionally, creating a dApp that manages multiple types of tokens would require a separate smart contract for each type, which can be cumbersome and inefficient
With ERC-1155, developers can create a single smart contract that manages both fungible and non-fungible tokens, which reduces the overall complexity of the dApp
Another advantage of ERC-1155 is that it allows for the creation of semi-fungible tokens
These are tokens that have some fungible and some non-fungible properties
For example, a game item might have a set of properties that are unique to that item (making it non-fungible), but also have a set of properties that are shared among multiple items (making it fungible)
This makes it easier to manage in-game items and provides greater flexibility for game developers
ERC-1155 also supports batch transfers, which allow for multiple tokens to be transferred in a single transaction
This can reduce gas costs and improve overall efficiency when transferring large numbers of tokens
Overall, ERC-1155 is a flexible and efficient token standard that provides a range of benefits for developers creating dApps that manage multiple types of tokens
It has been adopted by a number of projects in the gaming and collectibles space, but has potential applications in other industries as well.
