Taproot Assets is a new protocol built by Lightning Labs that can be used for minting tokens and creating collectibles using the power of Taproot to derive from user-defined meta-data such as images or files. This feature is available on Voltage.
Once you see that, you are ready to go! As of this writing, Taproot Assets only uses the on-chain features of your LND node. The Taproot Assets protocol will be lightning native in the near future. Be sure to have some bitcoin in your on-chain wallet of your node to mint and send assets.
