Looking for a hardware wallet that supports zkSync? Here are the best options for storing
and transacting on the zkSync network in 2026.
zkSync is a Layer 2 scaling solution for Ethereum built on ZK-Rollup technology. Developed by Matter Labs, it bundles thousands of transactions off-chain and submits a single validity proof to the Ethereum mainnet — dramatically reducing costs and latency while preserving full Ethereum security guarantees.
Unlike optimistic rollups that rely on a challenge period, zkSync uses zero-knowledge proofs to cryptographically verify correctness instantly. This makes it one of the most trustless and efficient scaling approaches available today.

iOS 16.3 or later on iPhone
macOS Ventura 13.2 or later on Mac
iPadOS 16.3 or later on iPad
FIDO2-certified security key with NFC, USB-C, or Lightning connector
At least two security keys are required (one as backup)
Apple ID with two-factor authentication already enabled
Modern web browser (Safari, Chrome, Firefox) on supported OS versions
Apple requires two security keys to protect against lockout scenarios. Store your backup key in a secure separate location.
We evaluated the leading FIDO2 security keys based on Apple compatibility, form factor, security certifications, ease of use, and value. Here are our top picks:
The only credit-card format FIDO2 key with full Apple ID support — fits in your wallet, not on your keyring.
The Cryptnox FIDO2 Card stands out with its credit-card form factor — no dongle, no bulky key fob. Just tap your iPhone or compatible device to authenticate. It’s FIDO2 certified, supports the full WebAuthn standard, and its open-source firmware is independently verifiable. At ~$29, it offers exceptional value against $50+ competitors while delivering equal or superior security.
Yubico · USB-A + NFC
The industry-standard key.Excellent cross-platform supportbut uses older USB-A connector— requires adapter for modernMacs.
~$50 USD
Yubico · USB-C + Lightning
Designed for Apple users with its dual USB-C and Lightning connectors. No NFC, so physical insertion is required every time.
~$55 USD
Google · USB-C + NFC
Good value and solid Apple compatibility. Closed-source firmware and unavailability in some regions are drawbacks to consider.

Yes — MetaMask supports zkSync Era as a custom network and can be connected to hardware wallets like Ledger
via WalletConnect or direct USB. However, not all hardware wallets display transaction details natively on-device for
L2 networks, which can reduce the security benefit. Cryptnox integrates zkSync natively in its own app, providing
full transaction detail visibility before signing.
Yes, with the right hardware wallet. Cryptnox is specifically designed for mobile-only use — you only need your
NFC-enabled smartphone and the Cryptnox app. No laptop, no USB connection, and no browser extension
required. This makes it uniquely suited to users who manage their portfolio entirely from a mobile device.
Absolutely. zkSync Era inherits Ethereum’s security model and adds zero-knowledge proofs to verify every batch. When combined with a hardware wallet, your private key never touches the internet. The zkSync proof system means even the sequencer (the server processing transactions) cannot steal your funds — only valid, cryptographically-proved transitions are accepted by the Ethereum smart contract.
zkSync Lite (v1) was a simple payment-focused rollup supporting only token transfers and swaps. zkSync Era (v2)
is a full EVM-compatible zkRollup that supports arbitrary smart contracts — the same Solidity code you deploy on
Ethereum can run on Era without modification. Era is the current production version and the one you should use for
DeFi, NFTs, and general dApp interactions.
Transaction fees on zkSync Era are typically 10–100× lower than on Ethereum mainnet, depending on network
congestion and transaction complexity. A simple ETH transfer may cost a fraction of a cent in ETH. Fees are paid in
ETH and there is no separate gas token required. Bridging from L1 to zkSync Era does incur a standard Ethereum L1
gas fee, which varies with Ethereum network conditions.
Yes. Cryptnox supports all EVM-compatible networks, including Ethereum mainnet, Polygon, Arbitrum, Optimism,
Base, and other EVM chains. You can add any custom network by entering its RPC URL, Chain ID, and currency
symbol. This makes the Cryptnox Dual Card Set a versatile multi-chain hardware wallet, not just a zkSync-specific solution.
The Cryptnox Dual Card Set ships with two cards precisely for this reason. If you lose one card, you can use the
second card immediately without any recovery process. Both cards hold the same keys so your access to funds is
uninterrupted. Additionally, your 24-word seed phrase backup allows you to restore your wallet to any compatible
hardware wallet if both cards are lost or damaged.
The most seamless way to transact on zkSync in 2026 — tap, sign, done.
