Python wrapper for cardano-cli for working with cardano cluster
Project description
README for cardano-clusterlib
Python wrapper for cardano-cli for working with cardano cluster.
Installation
# create and activate virtual env
$ python3 -m venv .env
$ . .env/bin/activate
# install it from PyPI
$ pip install cardano-clusterlib
# - OR - install it in develop mode together with dev requirements
$ make install
Usage
Needs working cardano-cli (the command is available on PATH, cardano-node is running, CARDANO_NODE_SOCKET_PATH is set). In state_dir it expects "shelley/genesis.json".
from cardano_clusterlib import clusterlib
# instantiate `ClusterLib`
cluster = clusterlib.ClusterLib(state_dir="path/to/cluster/state_dir")
# specify where to send funds and amounts to send
destinations = [clusterlib.TxOut(address=dst_address, amount=amount_lovelace)]
# provide keys needed for signing the transaction
tx_files = clusterlib.TxFiles(signing_key_files=[src_skey_file])
# build, sign and submit the transaction
tx_raw_output = cluster.send_funds(
src_address=src_address,
destinations=destinations,
tx_name="send_funds",
tx_files=tx_files,
)
# wait for two new blocks to make sure the transaction is on the ledger
cluster.wait_for_new_block(new_blocks=2)
# check that the funds were received
cluster.get_utxo(dst_address)
See cardano-node-tests for more examples, e.g. minting new tokens.
