Few things in crypto trigger a heart rate spike quite like opening your exchange app and seeing a balance of zero. Kraken users experienced exactly that scenario when a display bug started showing €0 available for the Instant Buy feature on the exchange’s mobile app.

Kraken confirmed the issue on its status page on July 28, 2026, at 11:58 UTC, classifying it under the dry but descriptive label “Issues with EUR balance for Instant Buy on Kraken App.” The good news: nobody’s funds have actually disappeared. The bad news: staring at a zero balance is never a fun experience, regardless of the explanation.

What’s actually happening

The bug is a front-end display problem isolated to the Kraken mobile app. When some users navigate to the Instant Buy screen, their EUR balance reads as €0, even though their actual account holdings remain intact and untouched.

The Instant Buy feature itself still works. Users just need to hop over to the Kraken website to execute purchases while the mobile app gets sorted out. Non-EUR assets and other trading functionalities across the platform are completely unaffected. There are no reports of broader outages, no security breaches, and no indication that the issue extends beyond this specific EUR display in the app’s Instant Buy interface.

Kraken has not disclosed a root cause or provided a timeline for a fix, which suggests the investigation is still in its early stages. A separate, unrelated incident involving Conflux (CFX) and GMX (GMX) on the FIX/WS API was reported earlier on July 22, 2026, but the exchange has confirmed that the two issues have zero connection to each other.

Context matters: why users are on edge

Kraken, founded in 2011 and publicly launched in 2013, is one of the longest-running crypto exchanges in the industry.

It’s also worth noting that Kraken’s Instant Buy feature has historically carried higher fees compared to the exchange’s Pro trading interface. That means the users encountering this bug are often the more casual, convenience-oriented segment of Kraken’s user base.

What this means for investors

The broader trading ecosystem on Kraken appears stable. Non-EUR pairs, advanced trading tools, and API-based activity are all functioning normally.

The workaround, using the Kraken website instead of the app, is functional but clunky. Mobile-first users don’t want to be told to open a browser.
