How scoring works →Summary
Inverse Finance is an Ethereum-based DeFi protocol known for its DOLA stablecoin and FiRM fixed-rate lending market, founded in late 2020 by Nour Haridy. The protocol suffered two oracle price manipulation exploits within two months in 2022 — the first in April for approximately $15.6 million and the second in June for a protocol loss of approximately $5.8 million — collectively representing one of the most significant serial oracle attack sequences in DeFi history. The protocol has since deprecated the vulnerable Anchor and Frontier lending markets, rebuilt on FiRM with Chainlink oracles, and undertaken a multi-year bad-debt repayment program.
