Crypto Trader Loses Nearly $50M in Aave Trade, Protocol Offers $600K Fee Refund
A crypto trader lost nearly all of a $50 million USDT investment attempting to buy Aave’s governance token (AAVE) through Aave’s decentralized trading interface. The trade, vastly exceeding available liquidity, triggered a warning about “extraordinary slippage,” but the user manually confirmed and proceeded via mobile device. The transaction returned only 324 AAVE tokens, worth about $36,100 at the time—resulting in a loss of roughly $49.96 million. Aave personnel clarified that the main issue was extreme price impact, not slippage, as the quoted rate for the large trade was already extremely poor before completion. Kulechov, Aave’s founder, stated the team will try to return about $600,000 in transaction fees to the trader. The trade was routed through CoW Swap and executed as designed, only after explicit user confirmation. The incident highlights the risks of executing large trades in low-liquidity environments on decentralized exchanges and suggests a need for stronger user protection measures without compromising platform openness.
