An address withdrew 10,057 ETH from a major exchange and transferred it to the Lido ecosystem for staking, receiving an equivalent amount of stETH. Subsequently, the address used the obtained stETH as collateral in the Aave lending protocol and successfully borrowed 45 million USDT. Interestingly, the borrowed USDT was not withdrawn but immediately flowed back into the market to buy 13,461 stETH. This series of operations demonstrates the sophisticated capital allocation strategy of whale addresses in the DeFi ecosystem—earning yields through staking and leveraging borrowing to expand position size.
