Sparrow Wallet releases v2.5.4 security update, independent verification scope expanded

According to Bitcoin News, Sparrow Wallet v2.5.4 has been released after extensive AI-assisted review, containing multiple security enhancement updates aimed at reducing users' reliance on external servers such as Electrum.

Additionally, this version strengthens Ledger, Keycard, Trezor, Payjoin, PSBT, and multi-signature handling, removes Bitcoin Core credentials and other confidential information from debug logs, restricts existing wallet and backup directory permissions to owner access only, closes local DNS resolution leaks when using Tor, and enhances wallet import, signing, downloading, and server response verification. This update expands Sparrow Wallet's scope for independently verifying transaction data, hardware devices, and other inputs, reducing reliance on external servers for data provision.
