Ethereum block builder Titan Builder has achieved a remarkable milestone, earning $34.5 million in a single day, according to DefiLlama data. This earnings figure surpasses that of Tether, which recorded $16.43 million, positioning Titan Builder as the top earner in the period ending March 13. The significant profit for Titan Builder was largely attributed to a transaction involving a user on CoWSwap. The user attempted to exchange approximately $50.43 million in aEthUSDT for AAVE but received only about 327 aEthAAVE, valued at roughly $36,000, due to a slippage exceeding 99%. This transaction resulted in Titan Builder profiting approximately $34 million.
