Joseph Lubin added another 30,000 ETH to Maker vaults, increasing the collateral posted to 110,000 ETH across three vaults. The added ETH was worth about $47.12 million at current prices, while the total pledged collateral was about $171 million, according to Onchain Lens. Against that collateral, Lubin has borrowed 259.05 million DAI, a crypto-backed stablecoin, and the latest deposit was made to reduce liquidation risk.
