Oracles (OEV)

Oracle Extractable Value (OEV) is a type of MEV that arises whenever an Oracle updates its data feed on the blockchain via the public mempool.

With MEV Blocker, Oracles can sidestep the public mempool, directing data feed updates to a private mempool where bots compete to arbitrage the forecasted state changes. This approach allows Oracles to retain up to 90% of the value generated by the update, in contrast to the public mempool model where this value is typically captured by MEV bots and validators.
