Dynamic NFT Project Examples

Bring your Web 2 use case into Web 3 by creating a dynamic NFT project.


  • Music dApp with Songs as NFTs
    • Update the number of listens, favorites, shares, number of appearances on top 100 billboards, and number of (positive/negative) reviews written.
  • Progression of Art
    • Progression of art as it's in progress
      • Example: early sketch → first painting → paint overs → draft → finalization
    • Capture reviews, feedback, likes, etc., that increase the value of the art.
Building Dynamic NFT Wallet


We have a server-based wallet to show NFTs on-chain and metadata from Fluree

  • Make it client based, similar to Nami
    • Sign Fluree and Cardano transactions
    • Display NFTs together with dynamic properties taken from Fluree DB
Web 3 Games Use Cases

Any game use case is valid!


  • Upgradable Items/character
    • Level
    • Strength
    • Score
  • Saves
    • As the progress of a single player/character which can be saved for later. Some games require some level of completeness to unlock, for example locations. Players sometimes download 100% complete profile to see what the location, weapon or character looks like then
    • As game restore mechanism - some time ago there was situation when someone infected World Of Warcraft in a way where players’ characters upgraded from a long time had been killed in the game with no possibility to restore them. If saves are stored on the blockchain, in similar situation the game could be restored by restoring player's public saves.
