If you hold Solana (SOL) or Cardano (ADA), you need a hardware wallet that supports both non-EVM chains natively. We tested the top contenders — Keystone 3 Pro, Tangem, and BitBox02 — comparing air-gapped QR security, card-based portability, and USB connectivity. Here's which one fits your stack.
If you hold Solana (SOL) or Cardano (ADA), you already know they aren't Ethereum. Both chains run their own virtual machines, their own wallet ecosystems, and their own security assumptions. A hardware wallet that only speaks EVM won't cut it.
Cold storage for non-EVM assets means finding a device that integrates directly with wallets like Phantom (Solana) and Eternl (Cardano) — and ideally doesn't require a USB cable or a battery charge every time you sign a transaction. Here are the three best hardware wallets for Solana and Cardano right now.
The Keystone 3 Pro is the only device on this list that supports both Solana and Cardano natively via QR-based signing.1 That means it never connects to your computer or phone by wire or Bluetooth. You sign transactions by scanning animated QR codes on screen, which keeps your private keys physically isolated from any potentially compromised host device.
It pairs with Phantom (Solana), Eternl (Cardano), NuFi, MetaMask, OKX Wallet, and Rabby.1 The large color touchscreen makes reviewing transaction details straightforward, and the open-source firmware has been audited by third-party security firms.
Best for: users who want maximum physical isolation and don't mind scanning a few QR codes per transaction.
Tangem takes a completely different approach: your private keys live on a tamper-resistant chip embedded in a credit-card-sized piece of metal. No battery, no screen, no cables. You tap the card to your phone via NFC and sign transactions through the Tangem app.
Tangem added native Cardano support (including Cardano native tokens) in mid-2024, and it has supported Solana for even longer.2 The security model relies on the chip's EAL6+ certification — the same grade used in passports and payment cards. If you lose the card, your funds are gone unless you have a backup card (sold in sets of two or three).
Best for: users who prioritize portability and want a wallet that disappears into a wallet slot.
BitBox02 is a Swiss-made hardware wallet with a strong reputation for security and transparency. It supports Bitcoin, Ethereum, and a growing list of altcoins. While its Solana and Cardano support isn't as front-and-center as the Keystone or Tangem, it's a reliable multi-chain option for users who prefer a wired connection and want the peace of mind of a fully open-source design.
The device uses a microSD card slot for backup (no seed phrase typed into a computer) and offers a unique "BitBoxApp" experience for managing multiple chains. It's a solid pick if you're already in the BitBox ecosystem or want a device that leans heavily on Bitcoin-first security principles while still covering SOL and ADA.
Best for: users who want Swiss engineering, USB connectivity, and a proven track record.
| Feature | Keystone 3 Pro | Tangem | BitBox02 |
|---|---|---|---|
| Connectivity | Air-gapped (QR) | NFC (phone tap) | USB (wired) |
| Solana support | Native via Phantom | Native via Tangem app | Via BitBoxApp |
| Cardano support | Native via Eternl | Native (incl. CNTs) | Via BitBoxApp |
| Screen | Large color touch | None | Small monochrome |
| Backup method | Seed phrase (metal) | Backup cards (2/3 set) | microSD + seed |
The common thread: all three devices keep your private keys offline, which is the whole point of a hardware wallet. But they differ in how you interact with them day to day.
For Solana and Cardano specifically, the Keystone 3 Pro offers the widest software wallet compatibility and the strongest isolation. Tangem is the best choice if you want something you can carry everywhere. BitBox02 is the conservative pick for users who want Swiss engineering and don't mind a cable.
