Add URIs (assets)

In the context of blockchain and non-fungible tokens (NFTs), the ESDTRoleNFTAddURI role is a specific permission assigned to users that allows them to append additional Uniform Resource Identifiers (URIs) to a designated eStandard Digital Token (ESDT). This role is critical as it enables the dynamic updating of NFT metadata without altering the underlying asset. It's important to note that when a URI is added by a user with this role, it does not overwrite or replace any pre-existing URIs associated with the NFT. This functionality ensures that all historical data remains intact and accessible, providing a comprehensive digital footprint of the asset's evolution over time.

This feature is particularly beneficial in various applications such as digital art, collectibles, and other blockchain-based assets where maintaining a record of updates, provenance, and additional information is crucial. The ability to add URIs without replacing previous ones allows for a more robust and detailed description of the NFT, which can enhance its value, provenance, and appeal to collectors. For platforms and projects utilizing this feature, it's important to ensure that users understand their roles and the implications of adding URIs, as this can significantly impact the user experience and the perceived value of the NFTs.
