How to check TRC20 token balance?

[Endogen]

How do i check the balance of a TRC20 token for a given TRX address?

[Endogen]

Derived from what i found in the README i think the way to get the balance of a TRC20 token (in this case the WIN token) should look like this:

from tronapi import Tron

# Source for ABI: https://tronscan.org/#/token20/TLa2f6VPqDgRE67v1736s7bJ8Ray5wYjU7/code
contract_abi = '[{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"spender","type":"address"},{"name":"value","type":"uint256"}],"name":"approve","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"from","type":"address"},{"name":"to","type":"address"},{"name":"value","type":"uint256"}],"name":"transferFrom","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"decimals","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"spender","type":"address"},{"name":"addedValue","type":"uint256"}],"name":"increaseAllowance","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"to","type":"address"},{"name":"value","type":"uint256"}],"name":"mint","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"value","type":"uint256"}],"name":"burn","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"owner","type":"address"}],"name":"balanceOf","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"from","type":"address"},{"name":"value","type":"uint256"}],"name":"burnFrom","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"account","type":"address"}],"name":"addMinter","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[],"name":"renounceMinter","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"spender","type":"address"},{"name":"subtractedValue","type":"uint256"}],"name":"decreaseAllowance","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"to","type":"address"},{"name":"value","type":"uint256"}],"name":"transfer","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"account","type":"address"}],"name":"isMinter","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"owner","type":"address"},{"name":"spender","type":"address"}],"name":"allowance","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[{"name":"name","type":"string"},{"name":"symbol","type":"string"},{"name":"decimals","type":"uint8"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"account","type":"address"}],"name":"MinterAdded","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"account","type":"address"}],"name":"MinterRemoved","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"owner","type":"address"},{"indexed":true,"name":"spender","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Approval","type":"event"}]'

tron = Tron()
contract = tron.trx.contract("TLa2f6VPqDgRE67v1736s7bJ8Ray5wYjU7", abi=contract_abi)
balance = contract.functions.balanceOf("TXRZqGMEXsGTX6AQtcSgYknos93hqw18P7")

print(balance)

But by calling that i get this error:
eth_abi.exceptions.NoEntriesFound: No matching entries for 'address' in encoder registry

What am i doing wrong here?

Turns out i was on the wrong path with my approach... Here is how to send WIN token - which will be easy to change to get the balance:

        trx_kwargs = dict()
        trx_kwargs["private_key"] = your_privkey
        trx_kwargs["default_address"] = your_base58_address

        tron = Tron(**trx_kwargs)

        kwargs = dict()
        kwargs["contract_address"] = tron.address.to_hex(wink_base58_contract_address)
        kwargs["function_selector"] = "transfer(address,uint256)"
        kwargs["fee_limit"] = 100000
        kwargs["call_value"] = 0
        kwargs["parameters"] = [
            {
                'type': 'address',
                'value': tron.address.to_hex(recipients_base58_address)
            },
            {
                'type': 'uint256',
                'value': 8000000
            }
        ]

        raw_tx = tron.transaction_builder.trigger_smart_contract(**kwargs)
        sign = tron.trx.sign(raw_tx["transaction"])
        result = tron.trx.broadcast(sign)
        
        print("RESULT", result)

@Endogen Can you please share the code which can be used for querying TRC20 balance?
Thanks a lot

But a TRX account needs to be activated first. Means you need to have, i think at least, 1 TRX in that address or otherwise the TRC20 balance will not be shown.
