Sparrow Wallet Updates with AI-Driven Fixes Following Code Review
Sparrow Wallet, a Bitcoin-focused wallet developer, has released an update after an AI-assisted code review found several fixes. The review was prompted by the release of unrestricted Chinese AI models and the ability to search large codebases for potential exploits.
Craig Raw, Sparrow's developer, said that most of the update's fixes came from the review, which included dozens of security changes aimed at reducing trust in outside services. The wallet now confirms transactions returned by Electrum servers, checks cryptographic proofs, and verifies the latest block in the chain before showing transactions as confirmed.
The update also strengthens BitBox02 hardware-wallet security and makes several other changes to Sparrow's handling of Ledger, Trezor, Keycard devices, multisignature wallets, Payjoin, wallet imports, and partially signed Bitcoin transactions. Raw recommended installing the update, but noted that users with air-gapped setups may be reluctant to make changes.
The review is part of a broader AI security push across the Bitcoin ecosystem, with developers using the technology to scan wallets, payment protocols, and code libraries for flaws before attackers find them.
