[Solved] Aepp-sdk-python: How to turn encoded Tx into TxObject?

Assuming I have an encoded and signed tx string like "tx_+KELBfh............ozXw=" how can I turn that back into a TxObject with its fields recipient_id, sender_id, amount and so on?

You have to decode base64 and then apply the RLP serialization for transactions. I did describe it the other way around here: [Solved] Building and signing raw transactions - #8 by philipp.chain

Hope this helps!
