- Support for preparing, fulfilling, and sending transactions to a Planetmint node.
- Retrieval of transactions by id.
The instructions below were tested on Ubuntu 16.04 LTS. They should also work on other Linux distributions and on macOS. The driver might work on Windows as well, but we do not guarantee it. We recommend to set up (e.g. via Docker on Windows) an Ubuntu VM there.
We recommend you use a virtual environment to install and update to the latest stable version using pip (or pip3):
pip install -U planetmint-driver
That will install the latest stable Planetmint Python Driver. If you want to install an Alpha, Beta or RC version of the Python Driver, use something like:
pip install -U planetmint_driver==0.11.1
The above command will install version 0.11.1. You can find a list of all versions in the release history page on PyPI.
More information on how to install the driver can be found in the Quickstart
- Planetmint Server Quickstart
- The Hitchhiker's Guide to Planetmint

Example: Create a divisible asset for Alice who issues 10 token to Bob so that he can use her Game Boy. Afterwards Bob spends 3 of these tokens.
If you want to send a transaction you need to Determine the Planetmint Root URL.
# import Planetmint and create an object
from planetmint_driver import Planetmint
bdb_root_url = 'https://example.com:9984'
bdb = Planetmint(bdb_root_url)
# generate a keypair
from planetmint_driver.crypto import generate_keypair
alice, bob = generate_keypair(), generate_keypair()
# create a digital asset for Alice
game_boy_token = {
'data': {
'token_for': {
'game_boy': {
'serial_number': 'LR35902'
}
},
'description': 'Time share token. Each token equals one hour of usage.',
},
}
# prepare the transaction with the digital asset and issue 10 tokens for Bob
prepared_token_tx = bdb.transactions.prepare(
operation='CREATE',
signers=alice.public_key,
recipients=[([bob.public_key], 10)],
asset=game_boy_token)
# fulfill and send the transaction
fulfilled_token_tx = bdb.transactions.fulfill(
prepared_token_tx,
private_keys=alice.private_key)
bdb.transactions.send_commit(fulfilled_token_tx)
# Use the tokens
# create the output and inout for the transaction
transfer_asset = {'id': fulfilled_token_tx['id']}
output_index = 0
output = fulfilled_token_tx['outputs'][output_index]
transfer_input = {'fulfillment': output['condition']['details'],
'fulfills': {'output_index': output_index,
'transaction_id': transfer_asset['id']},
'owners_before': output['public_keys']}
# prepare the transaction and use 3 tokens
prepared_transfer_tx = bdb.transactions.prepare(
operation='TRANSFER',
asset=transfer_asset,
inputs=transfer_input,
recipients=[([alice.public_key], 3), ([bob.public_key], 7)])
# fulfill and send the transaction
fulfilled_transfer_tx = bdb.transactions.fulfill(
prepared_transfer_tx,
private_keys=bob.private_key)
sent_transfer_tx = bdb.transactions.send_commit(fulfilled_transfer_tx)| Planetmint Server | Planetmint Driver |
