cardano-tools 0.2.0

Interfaces with the Cardano full-node software.

Cardano Tools

A python module for interacting with the Cardano blockchain.

The Cardano-Tools module provides functionality for interfacing with running full nodes on local or remote hosts. A running Cardano node is a prerequisite for using this package.

Provided tools include:

• Interfacing with the node:
  • Starting a relay or pool node locally and remotely.
  • Getting the node tip.
• Creating and administrating a wallet:
  • Create a new wallet address
  • Get UTXO list
  • Send a payment
  • Register a staking address
  • Get the blockchain tip
• Creating and administrating a stake pool:
  • Create block producing keys
  • Register a stake pool
  • Retire a stake pool

This project is developed and maintained by the team at Viper Staking.

Installation

You can install Cardano Tools from PyPI:

pip install cardano-tools

The Cardano Tools package supports Python 3.7 and above.

Examples

For more detailed examples, see the example scripts.

Shelley Tools

The ShelleyTools class provides an interface to the cardano-cli shelley commands. An example for creating a wallet is given below.

from cardano_tools import ShelleyTools

# Test Inputs (example paths)
path_to_cli = "/home/user/.cabal/bin/cardano-cli"
path_to_socket = "/home/user/relay-node/db/node.socket"
working_dir = "/home/user/.cardano-tools/"

# Create a ShelleyTools object
shelley = ShelleyTools(
    path_to_cli, 
    path_to_socket, 
    working_dir, 
    network="--testnet-magic 42"  # <-- For the testnet (default: --mainnet)
)

# Create a wallet address with both spending and staking keys.
print(shelley.make_address("my_wallet"))

Optionally, an SSH connection object may be specified if working with remote hosts.

from cardano_tools import ShelleyTools
from fabric import Connection

# Test Inputs (example paths)
path_to_cli = "/home/user/.cabal/bin/cardano-cli"
path_to_socket = "/home/user/relay-node/db/node.socket"
working_dir = "/home/user/.cardano-tools/"

# SSH connection to remote host
conn = Connection(
    host="hostname",
    user="admin",
    connect_kwargs={
        "key_filename": "/home/myuser/.ssh/private.key",
    },
)

shelley = ShelleyTools(
    path_to_cli, 
    path_to_socket, 
    working_dir,
    ssh=conn
)
