GoPlus Says Uniswap User Loss Was Driven by Same-Block Backrunner Arbitrage, Not a Sandwich Attack

A GoPlus analysis said a Uniswap trade that resulted in a large loss was primarily caused by same-block backrunner arbitrage rather than a sandwich attack. According to Foresight News, GoPlus posted on X that the routing contract sent a large amount of WETH into an AVAIL/WETH pool with very low liquidity, leading the user to buy AVAIL at a price far from the market rate, estimated at about 120 times the reasonable price. GoPlus said that within the same block, a backrunner then executed a reverse trade using a small amount of AVAIL priced closer to the real market level, extracting about 1,072 WETH from the pool. It added that most of the extracted funds, about 1,018 ETH, were paid as builder payment to Titan Builder.
