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 submission | mempool 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.
| # | Wallet | Won (Blocks) | Attempts (Blocks) | Contested Block % | First to Mempool % | Mempool Copying % | Suspected Frontrunning | Honest Attempts | Frontrunning Ratio | Victim / Was Frontrun | Private % | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
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. |
