## Opt-In for RBF
RBF is an opt-in Bitcoin feature. Transactions are only eligible for using RBF if they've been created with a special RBF flag. This is done by setting a transaction's sequence number (which is typically set automatically), so that it's more than 0 and less than 0xffffffff-1 (4294967294).

### Optional: Always Opt-In for RBF
If you prefer, you can _always_ opt in for RBF. Do so by running your `bitcoind` with the `-walletrbf` command. Once you've done this (and restarted your `bitcoind`), then all transactions should have a lower sequence number and be marked as `bip125-replaceable`.
