This code uses energy and bandwidth but does not transfer usdt.
why ?!!!

This code uses energy and bandwidth but does not transfer usdt. why ?!!!

hi, it worked the last time I tried. what is the result? do you have a txid?
maybe try increasing fee_limit , if error is "run out of gas"

    }
}

this is result

this is result

as seen on tronscan, it returned "Failed -Out of Energy>"
you can try increasing kwargs["fee_limit"] = 5000000 to kwargs["fee_limit"] = 20000000 (20 TRX) and try again

Thank you for your guidance
Yes, the transfer was done by increasing the fee limit.
that was perfect
<3 <3 <3 ;)

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!

?????? WhAT IS THIS???
