ERC-1155 is a smart contract standard that was proposed by Ethereum developer Dieter Shirley in 2017. It is a multi-token standard that allows for the creation and issuance of multiple tokens within a single smart contract. This is in contrast to the more commonly used ERC-20 standard, which allows for the creation of only a single token within a smart contract.
One of the main benefits of the ERC-1155 standard is that it allows for more efficient transactions on the Ethereum blockchain. Because the ERC-1155 standard allows for multiple tokens to be bundled together within a single smart contract, it can potentially reduce the number of transactions that need to be made on the blockchain. This can save on gas fees, which are the fees that are paid to process transactions on the Ethereum network.
Another benefit of the ERC-1155 standard is that it allows for the creation of “hybrid” tokens, which can represent both a physical asset and a digital asset. For example, a token could represent a physical gold coin, as well as a digital in-game item. This allows for greater flexibility in the types of assets that can be represented on the Ethereum blockchain.
One of the main use cases for the ERC-1155 standard is in the realm of gaming. The ability to bundle multiple in-game items together in a single transaction can greatly streamline the process of buying and selling items within a game. It can also make it easier to manage in-game economies, as the smart contract can enforce rules such as supply and demand.
However, the ERC-1155 standard is not without its drawbacks. One potential issue is that it may be more complex to implement than the ERC-20 standard. This could potentially make it more difficult for developers to create and deploy ERC-1155 contracts. Additionally, because the ERC-1155 standard allows for the creation of “hybrid” tokens, there may be regulatory concerns around the use of such tokens.
Despite these potential issues, the ERC-1155 standard has gained traction within the Ethereum community. It has been used in a number of successful projects, including the popular Cryptokitties game. It is likely that we will see continued adoption of the ERC-1155 standard in the future, particularly within the gaming industry.
In conclusion, the ERC-1155 standard is an innovative smart contract standard that offers a number of benefits over the more commonly used ERC-20 standard. It allows for the creation of multiple tokens within a single smart contract, which can lead to more efficient transactions and greater flexibility in the types of assets that can be represented on the blockchain. While it may be more complex to implement, the ERC-1155 standard has already been successful in a number of projects and is likely to see continued adoption in the future.
What are the minimum required functions of the ERC 1155 Smart Contract?
The ERC-1155 smart contract standard defines several functions that must be implemented in order for a contract to be compliant with the standard. These functions include:
balanceOf: This function returns the balance of a particular token for a given address.
ownerOf: This function returns the owner of a particular token.
safeTransferFrom: This function allows for the transfer of a token from one address to another in a safe and secure manner.
transferFrom: This function allows for the transfer of a token from one address to another.
mint: This function allows for the creation of new tokens.
burn: This function allows for the destruction of an existing token.
batchTransfer: This function allows for the transfer of multiple tokens at once.
In addition to these required functions, the ERC-1155 standard also defines several optional functions that a contract may choose to implement. These include functions for approving and revoking approvals for the transfer of tokens, as well as functions for querying the metadata and URI of a particular token.
It is worth noting that the ERC-1155 standard is still in the process of being finalized, and as such, the exact list of required and optional functions may change over time.
Variation / Upgrades
To my knowledge, there have not been any official variations or upgrades to the ERC-1155 smart contract standard. However, it is possible that individual developers or organizations may create their own variations of the standard or build upon it in order to add additional functionality or address specific use cases.
It is also worth noting that the ERC-1155 standard is still in the process of being finalized by the Ethereum community. As such, it is possible that additional functions or changes to the standard may be proposed and implemented in the future.
Overall, the ERC-1155 standard is a relatively new and evolving standard, and it is likely that we will see further development and innovation in this area in the coming years.
Flexible Token Standard
The ERC-1155 standard is often referred to as the “Flexible Token” standard because it allows for the creation of “hybrid” tokens. These are tokens that can represent both a physical asset and a digital asset. For example, a token could represent a physical gold coin, as well as a digital in-game item. This flexibility makes the ERC-1155 standard well-suited for a wide range of use cases.
Additionally, the ERC-1155 standard allows for the creation and issuance of multiple tokens within a single smart contract, which adds to its flexibility. This is in contrast to the more commonly used ERC-20 standard, which allows for the creation of only a single token within a smart contract.
Overall, the ERC-1155 standard’s ability to represent a wide range of assets and its ability to create multiple tokens within a single smart contract make it a very flexible and versatile standard. This is why it is often referred to as the “Flexible Token” standard.
It is also worth noting that the ERC-1155 standard is still in the process of being finalized by the Ethereum community. As such, it is possible that additional functions or changes to the standard may be proposed and implemented in the future.

How does ERC 1155 fit to NFT?
The ERC-1155 standard is well-suited for use with NFTs because it allows for the creation of “hybrid” tokens. These are tokens that can represent both a physical asset and a digital asset. This makes it possible to create NFTs that represent physical items, such as a physical collectible or a piece of art.
Additionally, the ERC-1155 standard allows for the creation and issuance of multiple tokens within a single smart contract. This means that it is possible to create a single contract that represents multiple NFTs. This can be particularly useful for applications that involve large numbers of NFTs, as it can help to reduce the number of transactions that need to be made on the blockchain.
Overall, the ERC-1155 standard is a powerful and flexible tool for creating and managing NFTs on the Ethereum blockchain. Its ability to represent both physical and digital assets, as well as its ability to create multiple tokens within a single contract, make it a well-suited standard for use with NFTs.
