Get the content through the Feeder Gateway of the batch_id that was provided in the previous step (or query previous batches):
wget -nv -q -O- https://gw.playground-v2.starkex.co/feeder_gateway/get_batch_info?batch_id=<batch_id>
The output will be similar to the one presented in Fig. 3. Lines 2–14 provide the information about the order tree root and the vault tree root, which represents the state. Lines 21 onward display the
information about the transactions in the batch; you will be able to spot your transactions using the tx_id that you saw in the Player script output (e.g., line 27). Pay close attention to the field was_replaced ; invalid transactions get the value true (as per the first and second transactions in Fig. 3; lines 28 and 40), valid transactions are not replaced, and are assigned the value false (line 52, Fig. 3.b). The StarkEx Playground is configured to skip the invalid transactions and not to replace them; however, in practice, this is a good indicator of whether the transaction was executed or not.
