that’s why we are always hoping that scammers do not have this tech knowledge equivalent to people like you.
My point was that if the private key had been leaked and multiple people had access to it, there would be probably someone making a non-RBF transaction.
There are many wallets that don't flag transactions as non-RBF.
But if you make non-RBF transaction can’t it still be replaced if the server or node is full RBF opt in?
With full-RBF, it's possible to replace the transaction with a new one even if it hasn't been flagged as RBF.
But I doubt there's any SPV wallet allowing you to do.
If you want to replace a non-RBF transaction with a new one, you need to broadcast it using your own node or build the raw transaction and use a tool with enabled full RBF setting. That's not easy for everyone.
