Yes the 2nd unconfirmed transaction is spending the unconfirmed output from the 1st transaction (A2).

The unconfirmed output from the 1st transaction (A2) is just the change returning to my wallet.

Thanks alot! I'll use electrum to do the CPFP transaction from B2

Hi, I made the common mistake of inputting fees that are too low (40 sats/byte) on 2 consecutive transactions, and i'm trying to do a CPFP transaction to push through the 2 stuck transactions in one go

Below are the 2 unconfirmed stuck transactions. If I do a 3rd CPFP transaction to move 'B2' into another address, would all 3 transactions go through if I put a high enough fee?

1st Txn input->output: A -> A1 (exch wallet) + A2 (own wallet)
2nd Txn input->output: A2 (own wallet) -> B2 (own wallet)

Thanks!
