Rubix Client SDK for Python

rubix-py is a lightweight client for the Rubix Blockchain Node, providing complete node interaction with minimal overhead.

Warning

This project is currently under active development. API changes and method signature updates may occur between releases. Please review the Release Notes before upgrading.

Installation

Run the following to install rubix-py

pip install rubix-py

Architecture

The architecture of rubix-py is pretty straightforward. It consists of the following classes:

• RubixClient: Responsible for connection to Rubix Blockchain Node
• Signer: Signs and performs Blockchain transactions and manages user's crypto keys.
• Querier: Queries information such as Token Balances, Smart Contract and NFT token chains, etc.

RubixClient has a set of internal methods to make API requests to the node. Both Signer and Querier consumes an instance of RubixClient which helps them to achieve their respective operations with the Blockchain node.

Let's have a look at a simple example of fetching RBT balance and transferring them:

from rubix.client import RubixClient
from rubix.signer import Signer
from rubix.querier import Querier

# Define the RubixClient by specifying the target Rubix node address
# and optionally providing timeout in seconds
client = RubixClient(node_url="http://localhost:20000", timeout=300)

# Define the Signer
# The Singer class takes two mandatory inputs:
# - rubixClient: Rubix Client instance
# - alias: Alias give to the account holding the cryptographic keypair. It can therefore
# be used everytime user wants to refer to the same keypair present in SDK config. If the
# keypair files are not present, it will be created. The keypair values will then depend on
# whether user passes a mnemonic or not 
#
# Optional Arguments:
# - mnemonic: Account can be recovered by passing a 24-word BIP-39 mnemonic. If not passed,
# a random mnemonic is generated.
# - config_path: Directory where files associated with SDK such as keypairs will be stored
signer = Signer(
    rubixClient=client,
    alias="nick",
    mnemonic="<Enter 24-word long BIP-39 mnemonic>",
    config_path="<Config Path for SDK dir>"
)

# Internally, a call is made to Rubix Node to create and register your DID
user_did = signer.did

# Retrieve the keypair which can be used for signing arbitrary message
keypair = signer.get_keypair()

# Retrieve the mnemonic
mnemonic = signer.get_mnemonic()

# Define the Querier
queryClient = Querier(
    rubixClient=client
)

# Check RBT balance
balance_info = queryClient.get_rbt_balance(user_did)
balance = balance_info["rbt"]

# Perform RBT Transfer
tx_response = signer.send_rbt_tokens(
    receiver_did="<Enter recipient DID>",
    rbt_amount=0.001,
    comment="Test RBT Transfer"
)

if tx_response["status"] is True:
    print("RBT Transfer Successful!")
else:
    print("RBT Transfer Failed!: ", tx_response.get("message", ""))
