Polkadot Warns Fearless Wallet Users to Move Funds After Private-Key Leak

The Polkadot Foundation warned users of the Fearless Wallet browser extension that a private-key leak exposed funds, urging holders to create fresh keys and move assets. An affected Chrome extension version with roughly 6,000 users was reportedly still listed at the time of the warning. A key compromise affecting a wallet tied to the Polkadot ecosystem raises security concerns for DOT holders and could weigh on confidence in the project's tooling.
