Hello,

I'm want to ask about RBF (Replace By Fee), It is could help stuck transactions or unconfirmed cause of fee with increasing of fee transactions.
So the question is : can we canceling the trasactions through decrease of fee(before get the blocks)? like do RBF with lowest sat/bytes ?
I'm neven have done with RBF, but I'm interest for this one.

Thanks,
Maddd.
