Update NFT Metadata

This guide explains how to update the metadata of an already minted NFT.

Dynamic NFTs

Dynamic NFTs allow you to update/change the metadata of an already minted NFT, such as its attributes, properties, and animationUrls. In this guide, we will be updating the attribute.

Minted NFT Metadata

Following is an example of an already-minted NFT. We will use this and update its description property on the token level.
