A DeFi trader recently created one of the most classic "money burning" moments in the market by evaporating nearly 50 million USD in just a few seconds after a massive swap to AAVE's token.
Specifically, this wallet attempted to swap 50.43 million USDT to buy AAVE in a single transaction. However, the liquidity of the pool at that time was too thin compared to the size of the order, causing the price to spike dramatically along the curve of the AMM. As a result, slippage reached about 99.9%.
Interestingly, the trading interface displayed a warning of "extraordinary slippage", but the user still ignored it and confirmed the transaction. The consequences:
• Threw in 50.43 million USDT
• Only received back 327 AAVE, worth about 36,000 USD.
This enormous amount did not actually "disappear", but was redistributed within the DeFi ecosystem:
• Liquidity providers of the pool received most of the USDT
• Arbitrage bots / MEV bots quickly exploited the price differences
• Protocol collected transaction fees.
The Aave protocol later confirmed that the system was not faulty, as the smart contract only executed the order that the user had confirmed. However, the team stated they would refund about 600,000 USD in transaction fees and consider improving the warning mechanism to prevent similar incidents in the future.
👉 This is seen as a typical example of the risks of DeFi:
permissionless finance means no one stops you from trading… but no one saves you from mistakes worth tens of millions of USD.
