 ### Introduction
 
-Hi, I see, I see almost NFT applications are using ERC721, so after the NFT start-up trend, there will be many companies that run out of capital and dissolve. At that time they will shutdown their servers and many of the images associated with the NFT will be inaccessible.  Should we need create a contract that allows the holder to update the image URI.
