Understanding ERC-1155: The Multi-Token Standard

What is ERC-1155?

ERC-1155 is a multi-token standard on the Ethereum blockchain that enables the creation and management of multiple types of tokens within a single contract. Introduced by Enjin, this standard provides a more efficient and flexible way to handle fungible, non-fungible, and semi-fungible tokens compared to its predecessors, ERC-20 and ERC-721.

Key Features of ERC-1155

Multi-Token Support

ERC-1155 supports multiple token types within a single smart contract. This means developers can manage different tokens, whether fungible or non-fungible, under one contract, significantly reducing the complexity and gas fees associated with deploying and interacting with multiple contracts.

Batch Operations

One of the standout features of ERC-1155 is its ability to perform batch operations. Users can transfer, approve, and manage multiple tokens in a single transaction, which enhances efficiency and reduces transaction costs.

Efficient Resource Utilization

By consolidating multiple token types into one contract, ERC-1155 optimizes the use of blockchain resources. This approach minimizes the need for redundant code and storage, resulting in lower gas fees and better scalability.

Enhanced Security

ERC-1155 incorporates several security improvements over previous standards. For instance, it includes features that prevent accidental token loss during transfers, ensuring safer and more reliable token management.

ERC-1155 vs. ERC-20 and ERC-721

ERC-20: The Fungible Token Standard

ERC-20 is the standard for fungible tokens on Ethereum. Each token is identical and interchangeable with any other token of the same type. While it has been widely adopted, ERC-20 does not support non-fungible tokens or batch operations, limiting its flexibility and efficiency.

ERC-721: The Non-Fungible Token Standard

ERC-721 introduced the concept of non-fungible tokens (NFTs), where each token is unique and not interchangeable. This standard has been pivotal in the rise of NFTs, but it also lacks support for batch operations and multi-token management, making it less efficient for applications involving numerous tokens.

ERC-1155: The Unified Approach

ERC-1155 combines the strengths of both ERC-20 and ERC-721. It supports both fungible and non-fungible tokens, along with semi-fungible tokens, within a single contract. This unified approach simplifies development and interaction with the blockchain, making it a versatile and powerful standard for modern applications.

Use Cases for ERC-1155


ERC-1155 is particularly well-suited for the gaming industry, where it can manage various in-game assets such as currencies, items, and characters. Games can benefit from the efficient handling of large numbers of tokens and the ability to bundle multiple asset transactions into a single operation.

Digital Art and Collectibles

Artists and creators can use ERC-1155 to issue both unique artworks (NFTs) and editions of the same piece (semi-fungible tokens). This flexibility allows for more innovative and diverse digital art experiences.

Supply Chain Management

ERC-1155 can streamline supply chain operations by tokenizing physical and digital assets, tracking their provenance, and facilitating batch transfers of goods. This improves transparency and efficiency in supply chain processes.


ERC-1155 represents a significant evolution in the Ethereum token standards, offering a more flexible, efficient, and secure way to manage multiple types of tokens. Its multi-token support, batch operations, and enhanced security features make it an ideal choice for a wide range of applications, from gaming and digital art to supply chain management. As blockchain technology continues to evolve, ERC-1155 is poised to play a crucial role in the development of more advanced and integrated decentralized ecosystems.
