This is a Charms app.

It is a simple fungible token managed by a reference NFT. The NFT has a state that specifies the remaining total supply of the tokens available to mint. If you control the NFT, you can mint new tokens.

Build with:

charms app build

The resulting RISC-V binary will show up at ./target/charms-app.

Get the verification key for the app with:

charms app vk

Test the app with a simple NFT mint example:

export app_vk=$(charms app vk)

# set to a UTXO you're spending (you can see what you have by running `b listunspent`)
export in_utxo_0="a2889190343435c86cd1c2b70e58efed0d101437a753e154dff1879008898cd2:2"

export app_id=$(echo -n "${in_utxo_0}" | sha256sum | cut -d' ' -f1)
export addr_0="tb1p3w06fgh64axkj3uphn4t258ehweccm367vkdhkvz8qzdagjctm8qaw2xyv"

cat ./spells/mint-nft.yaml | envsubst | charms app run
