Hello guys! I try to send BEP20 tokens in BSC, All the work fine, tx is subscribes, but doesnt pushed in Testnet, problem come in last line:
bscTxHash = web3_BSC.eth.sendRawTransaction(bsc_sign_tx_transferToken.rawTransaction)
Error: ValueError: {'code': -32000, 'message': 'invalid sender'}
If somebody have idea, I will be glad to see :)
