Zerion detected abnormal activity on app.zerion.io and pulled the web app offline. Blockaid has blocked the site. iOS, Android, and browser extensions remain fully safe.
Zerion flagged something unusual on its web app on April 11. The team moved fast. Within hours, app.zerion.io was offline.
The Web3 wallet platform confirmed the incident directly on X, urging users to stop using the web interface until further notice. “We’re investigating some abnormal activity on app.zerion.io,” Zerion wrote on X, adding that user funds remain safe inside self-custodial wallets. The team asked everyone to rely only on official communication from the account.
No details on the nature of the activity came immediately. The team did not confirm whether an exploit was involved or what triggered the alert.
Blockaid Steps In, Mobile Apps Stay Untouched
A second update followed. Zerion said it had proactively taken the web app down and that security firm @blockaid_ had also blocked the site as a precautionary step. “The iOS and Android Apps, Web Extension are SAFE and are not affected,” Zerion confirmed on X. The team said it is actively monitoring the situation.
The response puts Zerion among platforms that are choosing transparency and speed over waiting. This comes as crypto hacks dropped to $168 million in Q1 2026, down sharply from the year prior, though security incidents continue targeting web-based interfaces in particular.
Self-custodial architecture is the reason user funds are protected here. Because Zerion operates as a non-custodial wallet, the platform holds no private keys. Funds sit with the user. The web app going offline does not change that.
What Users Should Do Right Now
The advice from Zerion is clear. Avoid the web app entirely. Use the iOS app, the Android app, or the browser extension only. Do not interact with any links claiming to be app.zerion.io until the team confirms the platform is restored.
This pattern of a compromised frontend while underlying funds remain intact is not new. Just days ago, a fake trading firm compromised Drift Protocol through a sophisticated social engineering attack targeting the web interface and developer access. The nature of these incidents shows how web app layers often carry the most exposure in DeFi infrastructure.
Zerion said another update will come once the web app is restored. No timeline was given.

RAVE’s hype surge triggers a flood of copycat coin mania, as FF and INX expose the “pump-and-dump” scheme
Recently, altcoins represented by RAVE have sparked a fierce investment craze, but some old star projects like FF and INX have used this wave of hype to carry out “pump-and-dump” operations—rapidly driving up coin prices to lure retail investors to buy, and then dumping them heavily, causing the price to plunge rapidly. Such behavior not only exposes the project team’s funding difficulties, but also damages investors’ trust. Investors need to stay alert to signals like abnormal short-term surges in order to avoid the risk of being manipulated by the market.
