I am getting this error message when trying to call balanceOf function inside contract:
‘Could not transact with/call contract function, is contract deployed correctly and chain synced?’

Can someone point me in the right direction?
Thanks.

I am trying to get ERC20 contract balance in my MetaMask wallet using python. What am I doing wrong? Thanks.

import json
from web3 import Web3

MyWalletAddress = ‘…’
USDC_Address = ‘0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48’
API_KEY = ‘…’
ETHERSCAN_KEY = ‘…’

infura_url = 'https://mainnet.infura.io/v3/’+API_KEY
link = 'http://api.etherscan.io/api?module=contract&action=getabi&address=’+USDC_Address+’&apikey=’+ETHERSCAN_KEY

print (link)
f = requests.get(link)
print(f.text)

json = json.loads(f.text)
abi = json[‘result’]

w3 = Web3(Web3.HTTPProvider(infura_url))
contr = w3.eth.contract(MyWallet_address, abi=abi)

wei = contr.functions.balanceOf(MyWalletAddress).call()
balance = w3.fromWei(wei,‘ether’)
print (balance)
