  • The difference seems to have gone to the relay fee, but I don't understand myself why there would have to be a difference in relay fee, the txs seem identical in size. Commented Oct 10, 2023 at 16:59
  • Exactly. And to be honest, I don't know if 450 - 280 = 170 or if 450 - 170 = 280, the documentation is not clear.

As explained in my comment, the difference in output value is because of a different relay fee for these transactions.

I don't however understand why these transactions would have a different relay fee value. It might be an oversight.
