Enso Research Identifies Two 'Toxic Pools' That Manipulate Trade Execution, Causing $225K in Overstated Quotes

According to Enso Research, today (July 16) the firm identified 'toxic pools'—malicious liquidity pools designed to display accurate price estimates during transaction simulations while producing significantly different results after on-chain execution. Two active toxic pools were documented across Ethereum and Polygon, with one modified Curve pool processing over 129,000 successful swaps while delivering execution outcomes below quoted expectations, resulting in approximately $225,000 in overstated quotes, more than 37,000 failed transactions, and nearly $30,000 in associated gas costs. A separate Uniswap v4 hook caused a 99.1% transaction failure rate after repeatedly attracting routing systems.

Enso expanded its Enso Shield execution-protection system with new toxic-pool detection and verification features designed to analyze real-time blockchain conditions, monitor quote consistency, and identify discrepancies in transaction traces that may not appear in standard simulations.
