A flash loan attack drained $7 million from Origin Dollar, striking at the Ethereum-based protocol that markets itself as a yield-bearing stablecoin. The Origin Protocol team disclosed the breach through a Medium post after hackers exploited how the platform calculated asset prices.
OUSD generates returns for token holders while sitting in their wallets. The attack claimed funds from Origin Protocol itself, its founders, and employees. "At this time, there has been a loss of funds of around $7M, including over $1M of funds deposited by Origin and our founders and employees. We are very incentivised to give 1000% in resolving the issue in whatever way possible," the team stated in their announcement.
The attackers netted $2.25 million in DAI and another $1 million in ETH. They pulled off the theft in a single transaction, using a flash loan to distort the prices that Origin Dollar relied upon for calculations. This let them extract vastly more value than the collateral they had provided.
Flash loans operate on specific mechanics: a trader borrows money in huge amounts, executes swaps or other actions in a single blockchain block, and then the smart contract enforces automatic repayment. The loan needs no collateral upfront because the system ensures the loan gets repaid before the transaction finishes. Protocols that use market prices observed during the transaction become vulnerable when a flash loan distorts those prices.
The token market moved fast. OUSD trades at a $1 target but plummeted 46 percent within 24 hours to $0.50 on CoinGecko. The team told users to avoid trading OUSD on platforms like Uniswap and Sushiswap, where the displayed prices diverge from what the protocol's underlying assets support.
Origin Protocol moved to calm the situation. "We are not going away. This is not a rug pull or internal scam. Despite this setback, it is very much in our intention to make OUSD a safe, secure and successful product that builds on the broader Origin mission of peer-to-peer commerce," they wrote. The team vowed to push forward with the project.
