Polkadot Warns Fearless Wallet Users to Transfer Funds Following Private-Key Leak

Polkadot has issued an urgent warning advising Fearless Wallet users to move their assets after discovering a private-key leak ¹. The ecosystem's foundation urged affected token holders to create fresh keys immediately to protect their holdings ¹.

At the time of the warning, an impacted version of the browser extension remained listed on the Chrome Web Store, where it counted approximately 6,000 active users ¹. The vulnerability prompted calls directly from the foundation for all users of the affected build to secure their assets by generating new credentials ¹.

Extension Vulnerability and Fund Security

The advisory follows recurring security incidents surrounding browser extension wallets and key management across the digital asset sector ¹. Polkadot identified the exposure within the Fearless Wallet software, signaling immediate action for users holding balances tied to compromised software installations ¹.

At the time of writing, Polkadot's native token, $DOT, traded at $1.17, down 1.1% over the past 24 hours amid broader market movements. The foundation has directed users operating the affected Chrome extension build to complete the migration to fresh keys as the primary step to resolve the risk ¹.
