Moonwell's cbETH market still shows negative liquidity six months after an oracle misconfiguration

Live contract data for the lending protocol Moonwell shows its market for Coinbase Wrapped Staked ETH (cbETH) on Base sitting at 100.43% utilization with negative available liquidity. In a pooled lending market, utilization above 100% means borrowers have taken out more than the pool holds, so suppliers who did nothing wrong and were never liquidated cannot withdraw their collateral.

The cause was not an exploit in the usual sense. Between February 14 and 18, a single misconfiguration in the oracle pricing formula valued cbETH at about $1.12 instead of roughly $2,200, and the liquidation engine did exactly what it was written to do, seizing collateral whose value it read as having collapsed. Roughly 1,096 cbETH left the market, leaving a shortfall of about $1.8 million and roughly 181 affected borrowers on Base. The risk manager, Anthias Labs, cut supply and borrow caps to near zero to stop new exposure.

Moonwell's governance response proposed about $2.68 million in compensation, paid roughly $310,000 immediately from its Apollo treasury and committed the remaining balance to future protocol revenue. That plan addressed the borrowers who were liquidated at the wrong price. It did not fund the hole itself, so the suppliers unable to withdraw from a market at more than full utilization have no published path to get their funds back. The latest proposal allocates nothing to that gap.

Base carries $5.51 billion in total value locked and $12.57 billion in total value secured as a layer-2 network, up 14.4% over seven days, so the sums involved are small against the chain. The precedent is not small. A trusted off-contract input failed, the code executed correctly, and six months later a portion of user deposits remains frozen while the protocol repays from revenue it has not yet earned.
