Switchboard halts Aptos, Sui, IOTA, and Movement operations
Aptos (APT)

cryptobriefing.com reports that Switchboard halted operations on Aptos, Sui, IOTA, and Movement after detecting a potential security compromise. The incident began when an attacker exploited a compromised oracle key on IOTA to set the token's price to $10 million. This manipulation allowed the attacker to mint nearly 5 million VUSD through the Virtue CDP protocol.
The event triggered liquidations for 45 users and led to the freezing of exchange addresses. Switchboard shut down its Move-based deployments, which underpin the affected networks, during the transition from August 28 to 29. The protocol noted that its Solana deployment remained unaffected due to different code infrastructure.
Switchboard is collaborating with security agencies to investigate the breach. User funds appear intact outside of the specific IOTA incident, though the assessment may evolve.
How the market reacted
Whalio's own Binance spot order flow for APT, measured when this story was written up on 30 August 2026. Not the outlet's figures.
Whalio data shows APT trading at $0.5430 with a 1-hour buy ratio of 74.8%, indicating strong immediate buying pressure. This contrasts with the 4-hour buy ratio of 51.7% and the 24-hour ratio of 51.5%, suggesting recent inflows are outpacing the broader trend. The 1-hour volume delta is positive at $35,897, while the 24-hour delta sits at $77,051. This volume delta represents the net difference between buy and sell volume, showing that buyers are currently dominating the flow. The 1-hour metric shows significantly higher buying intensity than the longer-term averages.
The latest daily buy ratio of 46.3% sits at the 12th percentile of the last 281 days, against a median of 49.2% - weaker buying than most days.

Was that an ordinary day?
The same Binance spot measurements for APT, averaged over the days leading up to the story.
Over the preceding week, APT saw a 7-day average buy ratio of 51.1%, compared to a latest day reading of 51.5%, a difference of just 0.4 points.
