A lightweight Python toolkit for interacting with Ethereum-compatible chains.

• Client: Connect to any EVM node, get balances, nonces, block data
• ERC20Token: Inspect token metadata and balances
• TxSender: Sign and broadcast ETH transfers and contract calls
• GasHelper: EIP-1559 fee suggestions and gas estimation
• CLI: uno balance <addr> and uno block [number]

pip install -e .

from uno import connect
from uno.erc20 import ERC20Token
from uno.gas import GasHelper

w3_client = connect("https://mainnet.base.org")
print(f"Block: {w3_client.block_number}")
print(f"Balance: {w3_client.get_balance('0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045')} ETH")

gas = GasHelper(w3_client.w3)
fees = gas.suggest_fees()
print(f"Base fee: {fees['base_fee_gwei']:.2f} gwei")
