It's still unclear as to what really happened but if you have used the wallet before, read this:
Important Update: Who Needs to Take Action
We’ve published a step-by-step guide to help DCENT users quickly check whether the recent App Wallet action applies to them.
You need to take action if:
• You first installed the DCENT app before Nov 5, 2025, and
• You made transactions using the App Wallet on a version earlier than v8.1.0
You do NOT need to take action if:
• You first installed the app on or after Nov 5, 2025, or
• You only used a DCENT Hardware Wallet (Biometric Wallet, DCENT S, DCENT X) and never signed transactions with the App Wallet

This announcement came after Dcent have identified abnormal activity[1] involving the wallet app.
Based on the tweets, the hardware wallet users should not be affected (unless you used the hardware's seedphrase in the wallet app before).
