What is ERC-1948 Standard?

ERC-1948 is an Ethereum standard designed to introduce dynamic data storage capabilities for NFTs, allowing them to carry and update token-related data. This standard expands the static data model of traditional NFTs and enables the creation of more interactive and practical application scenarios.

ERC-1948 includes the following features:

Storing Dynamic Data An extension of ERC-721, it adds a 32-byte data field to NFTs, enabling the storage of dynamic data.

Readability The NFT owner can access and read the data stored within the token.

Writability The NFT owner can update the data stored within the token.

Why we choose ERC-1948?

Compared to traditional NFT standards like ERC-721 and ERC-1155, ERC-1948 offers greater flexibility and scalability, supporting more complex use cases. These include dynamic data updates and cross-application interactions, such as:

• Membership card status updates

• E-ticket usage tracking

• Attribute modifications for in-game items

• Version updates for digital artworks

• Authentication history for collectibles

These dynamic interaction scenarios closely align with the characteristics of RWAs. ERC-1948’s ability to handle dynamic data updates makes it an ideal solution for RWA applications, providing strong technical support for the digital management and use of real-world assets. This enables smarter and more efficient asset operations.
