According to Ai 姨 (@ai_9684xtpa), a whale collateralized $117 million worth of WETH and borrowed 68.13 million DAI, which is 58% of the collateral's value, causing a near liquidation scenario. This is due to MakerDAO's 'minimum collateralization ratio,' a core risk management mechanism designed to ensure system solvency and prevent bad debts from under-collateralization.
