Replace-by-fee has been a hot topic in the past few months. Our site already has 82 questions, but we probably have not everything covered yet.
Please use replace-by-fee to tag your questions, and consider asking about opt-in RBF, mempoolfullrbf, the criteria to evaluate replacement transactions, and any details on the mechanisms per which transactions in the mempool get replaced.
Please also check out previous work, add more answers where they are missing, improve content where it should be improved, and vote on what's there!
This weekly topic challenge runs from 2022-12-08 – 2022-12-14. Happy posting!
