Managing crypto across Ethereum, Solana, Bitcoin, and L2s is a real headache. We tested the top hardware wallets for multi-chain users — Keystone 3 Pro, Tangem, Trezor, and BitBox02 — comparing security, chain support, and everyday usability. Here's what we found.
If you hold assets on Ethereum, Solana, Bitcoin, and a handful of L2s, you already know the problem: no single wallet handles everything gracefully. Seed phrases get scattered, apps multiply, and every new chain means another security decision. The good news? Hardware wallets have caught up. The best crypto wallets for multi-chain users in 2025 combine broad chain support with real-world security that doesn't require a PhD to operate.
We looked at four of the strongest contenders — Keystone 3 Pro, Tangem, Trezor, and BitBox02 — and compared them on the dimensions that actually matter when you're juggling multiple blockchains.
Not all "multi-chain" support is equal. Some wallets let you view assets across chains but require separate software to transact. Others give you a unified interface but limit which tokens you can actually sign. The key differentiators:
The Keystone 3 Pro is the most security-conscious option on this list. It's fully air-gapped — it never connects to your computer or phone via cable or Bluetooth. All transaction data is transmitted via QR codes, which means there's no attack surface for remote exploits.1
It supports "almost all coins, chains, and tokens," including Bitcoin, Ethereum, Solana, and a wide range of EVM L2s.1 The large touchscreen makes verifying complex multi-chain transactions straightforward — you can actually read what you're signing. It also includes a fingerprint sensor for quick unlocking and is fully open-source, so the firmware can be independently audited.
The trade-off: air-gapped signing is slightly slower than NFC or USB. If you're making frequent small transactions, you might find the QR-scan workflow a bit tedious. But for holding and occasionally moving significant multi-chain portfolios, this is the gold standard.
Tangem takes the opposite approach: a credit-card-sized metal wallet that communicates via NFC. Tap it against your phone, and you're signing transactions in seconds. It supports "multiple blockchain networks and thousands of digital assets," making it genuinely multi-chain out of the box.2
The big selling point is simplicity. There's no battery, no screen, no cables — just the card and your phone. The seed phrase is generated and stored on the card's chip during setup; you can also create backup cards. This makes Tangem ideal as a daily-carry wallet for multi-chain users who move assets regularly.
The downside: no screen means you're trusting your phone to display the correct transaction details. For large holdings, the Keystone's on-device verification is safer. Tangem is excellent for amounts you use actively; less ideal for long-term cold storage of significant value.
Trezor has been around since the early days of hardware wallets, and its multi-chain support has matured considerably. Trezor Suite provides a unified dashboard for managing accounts across "several blockchain networks," including Bitcoin, Ethereum, and a growing list of L2s.3
The Model T offers a color touchscreen for on-device transaction verification, and the newer Trezor Safe models continue the open-source tradition. Trezor's firmware is fully open-source and has been audited extensively over the years, which matters if you're managing assets across many chains and want maximum transparency.
Where Trezor falls slightly behind: Solana support is still limited compared to Keystone or Tangem, and the USB connection (while reliable) isn't as convenient as NFC or as secure as air-gapped QR.
BitBox02 comes in two editions: Bitcoin-only and Multi. The Multi edition supports Bitcoin, Ethereum, and "EVM L2 (Optimism/Arbitrum/Base) partial through EVM wallets."4 It's made in Switzerland, with a focus on physical durability and a clean, minimal interface.
The device uses a microSD card for backup (no seed phrase to write down) and connects via USB. The companion app is well-designed and privacy-focused — no telemetry, no accounts. For multi-chain users who value Swiss manufacturing and a no-nonsense approach, BitBox02 is a solid choice.
The limitation: chain support is narrower than the others. Solana isn't supported natively, and L2 support is partial. If your portfolio is primarily Bitcoin and Ethereum (plus EVM L2s), this is a great fit. If you're deep into Solana or other non-EVM chains, look at Keystone or Tangem.
| Feature | Keystone 3 Pro | Tangem | Trezor (Model T/Safe) | BitBox02 Multi |
|---|---|---|---|---|
| Chains supported | Bitcoin, Ethereum, Solana, L2s, 9000+ assets | Bitcoin, Ethereum, Solana, 6000+ assets | Bitcoin, Ethereum, L2s (limited Solana) | Bitcoin, Ethereum, EVM L2s (partial) |
| Connection | Air-gapped (QR) | NFC | USB | USB |
| UX | Touchscreen, fingerprint | Tap phone, no screen | Touchscreen (Model T) | Buttons + companion app |
The hardware wallet market is splitting into two clear philosophies. Air-gapped wallets like the Keystone 3 Pro eliminate the USB attack vector entirely — no cable means no malware can reach the signing device. For multi-chain users managing significant value across many protocols, this is the most future-proof approach.
NFC wallets like Tangem prioritize the opposite: frictionless access. If you're the kind of person who wants to tap and go, and you're comfortable with the security model of a phone-based interface, NFC is hard to beat. The key is matching the wallet to your actual usage pattern — not just your ideal security posture.
For most multi-chain users, the choice comes down to how you use your crypto:
