Moonwell hit by $1.78M exploit as AI coding debate reaches DeFi
first published 2026-02-18T05:46:00Z
On Feb 15 a misconfigured Chainlink OEV wrapper oracle (enabled by Moonwell governance proposal MIP‑X43) briefly reported Coinbase Wrapped ETH (cbETH) at about $1 instead of ~ $2,200. Trading bots used the distorted price to seize 1,096.317 cbETH and liquidate positions, while some users over‑borrowed at the wrong price, producing approximately $1,779,044 in bad debt. Moonwell’s risk manager immediately cut supply and borrow caps and a governance vote will be held after the timelock to correct the oracle configuration.
