I want to get the token balance of RMRK in the chain statemine with py-substrate.

1 Answer 1

from substrateinterface import SubstrateInterface

ASSET_ID = 8  # RMRK.app

substrate = SubstrateInterface(url='wss://statemine-rpc.polkadot.io')
account_info = substrate.query(
    params=[ASSET_ID, ACCOUNT],

print(f'Balance: {account_info["balance"]}')
  • Is there full doc about how to use substrateinterface?

  • Sure, you can always check its repository: github.com/polkascan/py-substrate-interface. It also has a Github page here: polkascan.github.io/py-substrate-interface Mar 3, 2022 at 3:49
  • .Hi, The doc is very simple and can't help me. Can you help me to solve some issues? How to send a rmrk transaction ? I define the: call_module = "Assets" and call_function = 'transfer', call_params = { "id": 8, "target": target, 'amount': amount, }. But when I call "substrate.create_signed_extrinsic", the error "ValueError: Element "asset_id" of struct is missing in given value".

  • Without the whole code is hard to get it but maybe do what the error is point out? Like replacing "id": 8 by "asset_id": 8? Mar 4, 2022 at 18:36
