The MEV Builder That Raked $3.5M on Black Monday
The moment to showcase the power of searcher-builder integration.
During Black Monday, the biggest winner among builders is beaverbuild, as shown in our last post. But you would not guess who ranked the 2nd regarding builder rewards. It’s neither Titan nor Rsync; instead, it is the builder labeled MEV Builder 0x3b, which took 1,448 ETH, worth $3.5M.
How did it make this much during the turmoil of the market?
The craziest liquidation sent 358.7 ETH, worth $802K, to MEV Builder 0x3B in Block 20459000. Although it appears only to generate $87.8 profit, that's not the whole story.
Before the aforementioned TX, one liquidation sent 46 ETH, and after the biggest liquidation, one arbitrage gave 36 ETH to MEV Builder 0x3b.
The 2nd highest builder payout for MEV Builder 0x3B: 140 ETH, worth $325K, happened in this liquidation in Block 20459017.
