While playing with the API account/transfers/incoming and listening to a transaction from one of the exchanges I saw a very suspicious transaction. Sadly I do not remember a hash of the transaction, but its transaction version was 1744830466 .
Reading the documentation I see that:
The following version are currently support.
0x68 << 24 + 1 (1744830465 as 4 byte integer): the main network version
0x98 << 24 + 1 (-1744830463 as 4 byte integer): the test network version
And the version which I saw is not in this list. So how can this happen? Also how a wrong transaction can propagate in the network?
