OEV Searchers → In Depth

Getting started

This is a good starting place for searchers. It includes the list of good dApp candidates for searching, details how OEV auctions work and explains basic OEV searching strategy to simplify the onboarding of existing MEV searchers to OEV.

dApps catalog

Api3 feeds are used across many dApps, but not all are suitable for OEV searching. This catalog includes those dApps that are generating significant OEV amounts and are open for searchers to participate.

OEV dApps

The following table includes dApps which integrated OEV proxies and are good candidates for OEV searching. The chain and dApp alias define are unique for every market and are required when implementing searcher bots.

dApp	Chain	dApp alias
dTRINITY	Fraxtal	dtrinity
INIT Capital	Mantle	init
Lendle	Mantle	lendle
MachFi	Sonic	mach-finance
Vicuna Finance	Sonic	vicuna-finance
Yei Finance	Sei	yei

Legacy integrations

Some dApps are still using the legacy design of oracle proxies, which do not support OEV auctions. It's expected these will migrate the OEV supported ones soon. That said, searchers can already perform MEV with Signed APIs extraction.

Compound Finance USDe market	Mantle
Hana Finance	Taiko
INIT Capital	Blast
Orbit Protocol	Blast
Silo Finance RDNT market	Ethereum

From MEV searching

MEV searching has a well-established community and expertise in securing health and stability across many dApps and chains. We want to motivate this community to join OEV searching by outlining the steps to transition from MEV to OEV.

OEV can be considered an extension of MEV that searchers can capitalize on. While traditional searching prioritizes low latency, OEV searchers can secure guaranteed profits through exclusive priority access for updating data feeds.

The following is a short list of requirements to upgrade an existing MEV bot to participate in OEV searching:

1. Bridge funds to the OEV network
2. Deposit funds to the OevAuctionHouse contract
3. Monitor off-chain signed data for data feeds used by the dApp
4. Simulate the data feed update on-chain to determine OEV opportunities
5. Place a bid on the OEV Network
6. Wait for the auction to end
7. Provided the auction is won, use the award to update the on-chain data feed on target chain and capture the OEV

Most of these steps require small additions to the existing MEV bot, but it is required to understand the mental model behind OEV and our data feeds. Because of this, we recommend starting with an in-between solution we call MEV with Signed APIs.
