BitBox02 Bitcoin-only edition is the wallet I recommend when support fewer things, reduce risk is the point, not a limitation. Shift Crypto's own framing is blunt: the Bitcoin-only firmware has less code and therefore less attack surface, and it's locked to stay Bitcoin-only.
In practice, BitBox also does a few operational details unusually well: microSD-based backups in addition to recovery words, and a security posture that emphasizes verifiable firmware and anti-tampering checks. The main drawback is ecosystem friction—BitBox02 doesn't work on iPhone or iPad per the vendor's own product notes, so it's a better fit for desktop and Android-centric setups.
Keystone 3 Pro is the specialist tool in this list: a QR-signing workflow designed to keep the signer isolated from USB data paths during normal use. In the air-gapped category, the big win is its screen-first experience—transaction review is visually clear, and signing by scanning QR codes can be clean once you're practiced.
Keystone also markets a multi–secure element design; independent reviews in 2026 commonly cite three secure elements and emphasize the device's strong screen and QR flow. The honest con is that QR workflows are less forgiving: scanning can be finicky depending on the companion wallet's QR format and lighting conditions.
On the software side, MetaMask remains the default answer for best ethereum wallet apps because it's the compatibility layer most ecosystems assume exists. MetaMask is available as a browser extension and as a mobile app, and it explicitly supports using the same wallet across extension and mobile by importing the Secret Recovery Phrase.
Its strength is reach: it's widely supported, it handles multiple networks including custom networks, and its permissions model is familiar to anyone doing serious on-chain work. The weakness is also reach: a browser wallet is only as safe as your browser hygiene. If you use MetaMask, pair it with a hardware wallet for signing whenever meaningful value is involved.
BlueWallet is the best pick in the best bitcoin wallet apps category when you want a pragmatic mobile interface with serious operational features: watch-only wallets so you can monitor cold storage without exposing keys, multisig vault support, and broad import compatibility.
BlueWallet is also openly positioned as open-source and, as of its v8.0.0 line, the project continues to ship updates across iOS and Android. The trade-off is scope: it's purpose-built around Bitcoin, so it's not where you go for broad multi-chain coverage.
