The wallet will find the appropriate UTXO to use (the stategy cannot be specified here), calculate an appropriate fee for the tx, and send the change back to the sender. |

 | `just kill-all` | - | Terminate the local Regtest chain and clear all cached data. This will also stop the ordinals server and clear that data as well if it is present. |
 | `just mine-blocks` | `<wallet_name> <number_of_blocks_to_mine>` | On the Regtest network, mine the specified number of blocks. The program will generate a recipient address for the block rewards. Remember, coinbase transactions are only available for spending after 100 block confirmations. |

+| `just get-tx-out` | `<tx_hash> <vout_index> <num_confirmations>` | Get the tx outputs related to a specific transaction that was broadcast to the network. Optionally pass a minimum number of confirmations to filter out vouts with less than the specified number of confirmations. |
 | `just broadcast-tx` | `<signed_tx_hash> <max-fee-rate>` | Broadcast a signed transaction to the network. Optionally, pass a fee rate in sats/vByte that is the max fee rate you are willing to broadcast transactions for. Passing a fee rate of `0` will bypass all fee rate restrictions implemented by the wallet. |
 | `just get-spendable-balance` | `<address>` | Sum all UTXO amounts where the number of block confirmations is greater than or equal to 6. |
