CASE STUDY:Save on Liquidationswith Express Relay

Express Relay shares the liquidation value between your protocol and the searcher with the most competitive bid.
Protocols discount their collateral too much to ensure reliable liquidations. Most of the value then goes to miners.
The largest lending protocols alone have lost over $150 million to MEV. With Express Relay, you can take back control of your protocol’s value.
