A trader appears to have executed one of the most disastrous on-chain swaps in recent memory, turning roughly $50 million worth of assets into just about $36,000 in a single Ethereum transaction.
Blockchain data from Etherscan shows that the wallet first burned around 50.43 million aEthUSDT—an interest-bearing version of USDT used within the Aave lending protocol—to withdraw the same amount of regular USDT.
The funds were then routed through a trade executed via CoW Protocol, a platform designed to aggregate liquidity and find optimal trade routes across decentralized exchanges.
However, something went badly wrong.
Instead of receiving an equivalent value of tokens, the wallet ended up with only about 327 AAVE tokens, worth roughly $36,000 at the time of the transaction.
On paper, this makes it appear as though over $50 million was exchanged for a tiny fraction of its value.
The exact cause is still unclear, but analysts say several possibilities could explain the event. The trader may have routed the swap through an illiquid or manipulated trading pool, where pricing was extremely unfavorable.
Another possibility is a misconfigured trade order or routing error, which can occasionally occur in complex decentralized finance (DeFi) transactions involving multiple contracts.
Despite the eye-catching numbers, the incident is unlikely to move the market for Aave. The transaction resulted in only 327 AAVE tokens, a very small amount relative to the token’s overall liquidity and market capitalization.
