printer

Print like the Fed.

Here are a few commands to get started:

0. build charms from source https://github.com/CharmsDev/charms:

cargo install --profile=test --path . --locked --bin charms

1. In the printer repo root dir, run:

. ./script/export-vars-nft.sh

If it prints an error about wallet_dir, set wallet_dir and run again.

2. Now you're ready to prove a spell:

cat ./spells/mint-nft.yaml | envsubst | charms spell prove --app-bins=$app_bins --prev-txs=$prev_txs --funding-utxo=$funding_utxo --funding-utxo-value=$funding_utxo_value --change-address=$change_address --chain=cardano --mock > ./tmp/tx.draft.json

This will create ./tmp/tx.draft.json which can be signed and submitted to the Cardano network.

3. To see if the tx has a valid spell, you can run

charms tx show-spell --tx $(cat ./tmp/tx.draft.json | jq -r '.cborHex') --chain=cardano --mock

It should print something like
