Abstractions for the Polkadot ecosystem

PyPolkadot

Abstractions for the Polkadot ecosystem.

This package is a very opinionated wrapper around py-substrate-interface. It provides a simple synchronous interface for interacting with the Polkadot ecosystem. The PyPolkadot package can automatically detect when the metadata is outdated and refresh it behind the scenes. This ensures that developers don’t have to manually handle metadata updates.

Note: Light client functionality is not yet supported.

Installation

pip install PyPolkadot

Usage

Basic usage

from polkadot import *

# Initialize Polkadot instance
polka = Polkadot()  # Defaults to the mainnet relay chain

# Optionally, specify a custom RPC endpoint or use a testnet
polka = Polkadot(endpoint="wss://polkadot-rpc-tn.dwellir.com")

# Get account balance
balance = polka.get_balance("12pDATAH2rCakrYjo6UoYFtmTEUpSyePTum8U5x9QdySZuqn")
print(f"Balance: {balance} DOT")

# Create a Polkadot instance (testnet, defaults to Polkadot Westend)
polka = Polkadot(testnet=True)

# Create a new wallet
wallet1 = Wallet.create(polka)
address = wallet1.default_address

# Request tokens from the faucet (only on testnet)
faucet_tx = wallet1.faucet()

# Get balance
balance = wallet1.get_balance()

# Send tokens
receiver_address = "5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty"
tx_receipt = wallet1.send(1, receiver_address)
