A flash-loan oracle attack on Fantom drained ~$13.4M.
DEUS Finance was a derivatives and synthetic-asset protocol on Fantom that relied on a manipulable price oracle. In 2022 an attacker used flash loans to distort that oracle and drained roughly $13.4M.

☠️ Cause of death
Flash loans were used to manipulate the spot-price oracle feeding the protocol, enabling under-collateralized borrowing that drained funds.
📓 Lessons left behind
- —Never price collateral from a single manipulable pool.
- —Use TWAP or multi-source oracles.
- —Flash loans turn any spot oracle into a weapon.
🌱 The idea that survived
Robust oracle design
Reinforced manipulation-resistant, time-weighted, multi-source price oracles in DeFi.
