Waiting in the mempool is really something like the morning rush hour subway when it’s packed: you hit send, but your transaction just gets shoved into a “waiting area.” Miners/validators will pick the ones with higher tips first—or those that fit their own routes. So you end up going through: waiting forever without getting into a block, getting cut in line by others, gas prices getting jacked up to absurd levels, and in the end either getting stuck or failing, yet still paying fees for nothing… To put it plainly, you’re not “confirming”—you’re fighting a bunch of people for the same entrance.

Recently, AI agents for automatic interaction have been all the rage again. Some of it is storytelling hype, and some is really digging into security details. If you automate orders without considering this stretch of the mempool—getting squeezed in, getting front-run, getting sniped in the middle—then the whole experience becomes kind of mystical. Anyway, I’m not chasing explanations anymore. Accept the randomness: when it’s congested, move less; if you truly need to act, set an upper limit in advance, and if necessary, just resend/replace directly—don’t gamble with your feelings about the chain.
