Just happened. A hacker tried to manipulate the market with a $100 million flash loan, but ended up losing just the fees and ran away. 😂

This is actually the classic problem of traditional DeFi—flash loan attacks. The tactic is simple: within the same block, inflate the price by 100 times, borrow all assets, then dump the market and repay. After a series of maneuvers, the user’s liquidity pool is drained. Such incidents used to be almost impossible to prevent.

This time is different. The hacker targeted a new lending protocol that uses the APRO oracle. The script was ready: borrow → pump → borrow again → dump → repay. It looked flawless.

But as soon as he tried to pump the price, the problem arose. The oracle remained completely unchanged.

Why? The APRO’s TVWAP mechanism kicked in. This system immediately detected the anomaly: “The price on a certain DEX has increased 100 times, but the trading volume is only from your own trades? Other exchanges’ prices haven’t moved?” It instantly flagged the data as suspicious and excluded it.

The on-chain price stayed calm and steady. The hacker’s entire arbitrage logic was completely invalidated. The fees for the flash loan and gas costs had already been burned—ultimately, he lost tens of thousands of dollars and had to walk away in shame.

This is the true strength of an oracle’s defense. It doesn’t care how outrageous your price manipulation is; it looks at whether there is genuine trading volume supporting the price. Want to fool it? You’d have to buy up all the liquidity across the entire network.

Protocols protected by such oracles can sleep peacefully at night.
