Yes, I meant full-RBF. Is there actually any evidence that there's any mining pool that doesn't accept valid replacement transactions? I don't think so.
I'm pretty sure that a valid RBF replacement transaction can be successfully submitted e.g. via mempool.space's
Broadcast Transaction or similar well connected services like this.
Although, it'll require advanced knowledge or familiarity with the command line in some clients/wallets.
But definitely doable as long as its self-custodial.
I think so, too. In my opinion wallet software shouldn't prevent a user to assemble a valid replacement transaction, regardless of the RBF setting or if RBF is opted-out for a to-be-replaced transaction. At least, allow this as an advanced option.
I wonder how long e.g.
this small "donation" to Genesis block will remain unconfirmed. My node's mempool first saw it 2026-09-03T08:14:04Z, more than 7 weeks ago.
