Does Bitcoin use MEV to order your transactions like DeFi?

While Ethereum's MEV involves bots reordering transactions around DeFi activities, Bitcoin exhibits a quieter, 'soft MEV' driven by miners and pools at the mempool and policy layer. Miners determine transaction inclusion based on fee signals, mempool policies, and block templates, prioritizing packages with the highest effective fee rate when considering ancestors and children (ancestor-feerate mining). Bitcoin Core v28 introduced default full Replace-by-Fee (RBF) and limited package relay, further influencing ordering. Out-of-band routes, such as pool accelerators, and policy filters can also override the public fee auction, reducing transparency. For everyday users, this means small fee changes, using Child-Pays-for-Parent (CPFP) to sponsor stuck transactions, or utilizing accelerators can subtly influence whether their transaction clears first, even if broadcast later than others.
