for payment_amount,payment_address in payments:
  trx_kwargs = dict()
  trx_kwargs["private_key"] = pkey
  trx_kwargs["default_address"] = tron.address.from_private_key(pkey).base58

  tron = Tron(**trx_kwargs)

  kwargs = dict()
  kwargs["contract_address"] = tron.address.to_hex("TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t") # USDT contract address
  kwargs["function_selector"] = "transfer(address,uint256)" # function to call and types. for reference on tronscan it looks like this: transfer(address _to,uint256 _value)
  kwargs["fee_limit"] = 5000000 # fee limit in tron (5 TRX here)
  kwargs["call_value"] = 0 # how much tron to send to the contract (always keep this zero for transferring tokens)

  payment_amount = int(float(payment_amount))
  kwargs["parameters"] = [
  {
  'type': 'address',
  'value': tron.address.to_hex(payment_address)
  },
  {
  'type': 'uint256',
  'value': payment_amount * 1000000 # 1000000 = 1 USDT
  }
  ]

  raw_tx = tron.transaction_builder.trigger_smart_contract(**kwargs)
  signed = tron.trx.sign(raw_tx["transaction"])
  print(f"\n\nSENDING {payment_amount} USDT TO {payment_address} IN 2 SEC...\n")
  time.sleep(2)
  result = tron.trx.broadcast(signed)

  print("RESULT", result, "\n\n")

This is not working on my side. I do not have multi-signature authority. See result below.

RESULT {'code': 'SIGERROR', 'txid': '3455e6e8e17b2ac99725bf461cde9b505a5f5d516770f5f551700d3e2f7441d9', 'message': 'Validate signature error: 09a1c7cdf01973d5704f9469606a814a83107583c96b6ada4e7dc17c280f417e22d5d68fe7c607c682b8d12712a1d8adf2875cd9061e4de4d95094bdb65c2d641c is signed by TKx1TtevcLSMst73ZRZLKfVc7wEfpVwuBn but it is not contained of permission.'}

I am also want to send from a multi signature wallet which i have the same problem!
