User request: "Spend from my always-succeeds script"
Response:
# === Spend from Always-Succeeds Script ===
SCRIPT_ADDR=$(cat script.addr)
PAYMENT_ADDR=$(cat base.addr)
# 1. Query script UTxO
cardano-cli conway query utxo \
--address $SCRIPT_ADDR \

# Note the UTxO hash and index
# 2. Query payment UTxOs (for collateral)
cardano-cli conway query utxo \
--address $PAYMENT_ADDR \
--testnet-magic 1
# Select ADA-only UTxO for collateral
# 3. Create redeemer (for always-succeeds, can be unit)
