Sparrow Wallet has released version 2.5.4 after what it described as extensive AI-assisted review, adding a set of security-focused changes aimed at cutting users’ reliance on external servers such as Electrum. The release strengthens handling for Ledger, Keycard, Trezor, Payjoin, PSBTs, and multisig workflows, while also removing Bitcoin Core credentials and other sensitive information from debug logs. In addition, the update restricts permissions on existing wallet and backup directories so they are accessible only to the owner. Another fix addresses lingering local DNS resolution leaks when Tor is in use. The release also tightens validation around wallet imports, signing, downloads, and server responses. According to Bitcoin News, the main thrust of the update is a wider scope for independent verification of transaction data, hardware devices, and other inputs, reducing dependence on data supplied by external servers.
