What Counts as Frontrunning?

Frontrunning here means getting ahead on chain of a rival whose transaction you could already see. Two things must both be true: the wallet's submission reached the mempool after a rival's, and it still won the request. Arriving late and losing is just losing; arriving first and winning is just being fast.

Ordering is decided among publicly visible submissions only. A transaction sent privately is one no competitor could have reacted to, so it never makes anyone else late.

the wallet's submissionmempool ordering
Sent publicly, and it was the earliest public submission (or within 25 ms of it) first
Sent publicly, but another public submission was earlier late
Sent privately, while at least one rival was publicly visible unverifiable
Sent privately, and every rival was also private first

A late row that also won the request is counted under frontran. A late row that lost still counts as Mempool Copying — the wallet reacted to a rival either way, it just didn't bid high enough. That is why the two columns differ, and why the Frontrunning Ratio weighs wins-from-behind against the attempts a wallet made on its own information. unverifiable rows are what turn every one of those figures into a range: the low end assumes none of them were reacting, the high end assumes all of them were. first rows never contribute.

We saw someone attempt a proposal in the public mempool. You came along a few hundred milliseconds later with the same proposal and a higher bid.
We know you used your own information, because no-one came before you in the mempool.

Live races

Requests where more than one wallet had a proposal in the block where the proposal actually landed. Ordering is by when each participant's tx first reached our mempool listener. Requests contested by the same proposers, in the same block, with identical timings are shown as one card — that is one event, usually a batched transaction. Any difference in outcome, position or timing splits them apart again.

Filter by wallet — any wallet

Shows only races containing every wallet ticked, so picking two isolates the races where those two met.
