ERC-1155 vs ERC-721
The world of Ethereum tokens is vast, but two standards stand out when it comes to NFTs: ERC-721 and ERC-1155.
These token standards play a crucial role in defining how digital assets are created, managed, and traded on the blockchain.
Whether you’re an artist minting a one-of-a-kind NFT, a game developer designing in-game economies, or a collector navigating the NFT landscape, understanding the differences between these two standards is essential.
This glossary breaks down the key features, use cases, and distinctions of ERC-721 and ERC-1155 to help you choose the right standard for your project.
ERC-721
ERC-721 is a token standard for creating non-fungible tokens (NFTs) on the Ethereum blockchain. Each token created using this standard is unique and cannot be replaced or interchanged with another token.
Key Features:
- Every ERC-721 token has a unique ID.
- Enables verifiable ownership of digital assets.
- Typically used for NFTs representing art, collectibles, or real-world assets.
- Tokens must be deployed individually, which can be gas-intensive for large collections.
Examples: CryptoKitties, Bored Ape Yacht Club.
Pros:
- Perfect for creating unique, one-of-a-kind assets.
- Well-suited for digital art, collectibles, and rare items.
- Established standard with wide adoption and marketplace compatibility.
Cons:
- Gas-intensive for large-scale projects due to individual deployments.
- Limited functionality compared to newer standards like ERC-1155.
- Does not support batch operations or multiple token types in one contract.
ERC-1155
ERC-1155 is a token standard that supports the creation of fungible, non-fungible, and semi-fungible tokens within the same contract on the Ethereum blockchain.
Key Features:
- Allows the creation and management of multiple token types in a single contract, reducing gas costs.
- Supports fungible, non-fungible, and hybrid tokens.
- Enables batch transfers and operations, making it suitable for large-scale applications like gaming.
- Ideal for projects that require both fungible and non-fungible tokens, such as in-game assets and multi-asset marketplaces.
Examples: Gods Unchained, Enjin.
Pros:
- Highly gas-efficient for managing large collections or diverse token types.
- Supports batch transfers and operations, reducing transaction complexity.
- Combines fungible, non-fungible, and semi-fungible tokens in one contract.
Cons:
- Less established than ERC-721, with fewer implementations in certain niches.
- Complexity in design may not be necessary for simple, unique asset projects.
- Slightly steeper learning curve for developers new to multi-token standards.
ERC-1155 vs ERC-721 Comparison
Which Should You Use?
ERC-721
- You are creating unique, one-of-a-kind NFTs like digital art or rare collectibles.
- Your project does not require batch operations or multiple token types.
ERC-1155
- You need to create large collections with mixed token types (e.g., fungible game currencies and unique in-game items).
- Gas efficiency and scalability are priorities.
Conclusion
ERC-721 and ERC-1155 serve distinct purposes within the Ethereum ecosystem.
ERC-721 is the go-to standard for unique, standalone NFTs, while ERC-1155 is designed for projects requiring flexibility, scalability, and cost-efficiency.
By understanding the strengths and limitations of each, developers can choose the most suitable standard for their project.
