Lookonchain.com reports that Notional Finance’s escrow contract was suspected of being hacked, resulting in the theft of approximately $1.7 million in DAI and USDC. Specter monitoring, cited by PeckShield, identified the vulnerability in the fixed-rate lending protocol. The attacker converted the stolen assets into roughly 689.2 ETH before depositing the funds into Tornado Cash.
The project team is still confirming the exact cause of the attack and the final loss amount. In other market news, Binance listed MarsCoin (MARSCOIN) with a seed tag, triggering a 50% rally.

How the market reacted
Whalio's own Binance spot order flow for USDC, measured when this story was written up on 4 September 2026. Not the outlet's figures.
USDC is trading at $0.9999 with a 1-hour buy ratio of 54.6% and a 4-hour buy ratio of 56.0%, compared to a 24-hour ratio of 50.5%. This indicates that buying pressure is currently building in the short term relative to the daily average. The Volume Delta shows +$14,046,984 over the last hour and +$78,925,529 over the last four hours, signaling strong immediate net inflows. Over 24 hours, the Volume Delta is +$32,628,179, with a Cumulative Volume Delta (CVD) of +$128,322,170 at the close. Net buying occurred for 13 out of the last 24 hours, supporting the view that buyers are currently in control. Spot volume reached $3,495,289,742 with 719,738 trades in the same period.
The latest daily buy ratio of 49.8% sits at the 69th percentile of the last 281 days, against a median of 47.8% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for USDC, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 48.6%, making the current 24-hour ratio of 50.5% an unusual day with +1.9 points of relative strength. Volume was 1.39x the average, indicating significantly higher activity than usual. However, the 24-hour net buying period of 13 hours contrasts with the weekly data showing 0 days of net buying out of 7. The 8-day Volume Delta was -$393,136,835, suggesting that while today is active, the broader weekly trend has been dominated by net outflows. This marks a sharp reversal from the previous week's consistent lack of net buying days.
