frontrunning.xyz — UMA ManagedOptimisticOracleV2 proposer race analysis (Polygon)

Collision % — of the requests this wallet tried to propose, how many were contested in the winning block. A wallet that only ever appears where a competitor is already proposing is not finding its own work; high is suspicious.
First to mempool % — across contested requests, how often this wallet reached the public mempool first. Not conditioned on winning, so a wallet that keeps winning races it entered late scores low; low is bad.
Private % — winning txs that never reached our listener at all. Reads as evasion, but private submission is also a legitimate defence against being frontrun. Rates over samples under 10 are greyed and never highlighted.
