Arculus Wallet review

The Arculus Wallet turns cold storage into something the size of a credit card. Your private keys live on a certified secure chip inside a metal NFC card, and you sign transactions with a three-factor tap: unlock your phone, enter the app PIN, and tap the card. This Arculus Wallet review is based on setting it up from the box, funding it, sending and receiving, and testing recovery, so the verdict reflects living with it rather than reading a spec sheet.

The short version: it is the most frictionless way to own your keys. There is no battery, no cable and nothing to charge, and the three-factor security is genuinely strong. The trade is that you review every transaction on your phone rather than a device screen, and coin support is a focused list rather than a huge one.

Arculus Wallet at a glance

Before the detail, here is the Arculus Wallet in one table.

Security: EAL6+ and three-factor tap-to-sign

Security is where the Arculus earns its keep, and it rests on two things. The first is the chip. Your private keys are generated and stored on a CC EAL6+ certified secure element, the same bank-grade class of chip CompoSecure uses in the metal payment cards it makes for major banks. The keys never leave the card.

The second is the three-factor flow. To approve anything, you unlock your phone with a passcode or biometric, enter a six-digit PIN in the app, and physically tap the card. All three must pass, which is a real step up from the standard two-factor setup on many wallets. And because the card only ever communicates by a brief NFC tap, with no battery or radio of its own, it behaves much like an air-gapped device. There have been no public hacks since its 2021 launch.

Tap-to-sign: no battery, no cables

Using the Arculus is refreshingly simple. There is nothing to charge and no cable to find, because the card draws power from your phone's NFC field for the split second it is tapped. You prepare a transaction in the app, tap the card to sign, and you are done.

That simplicity is the whole appeal. It removes the two things that put people off traditional hardware wallets, the fiddly cables and the fear of hardware failure, while keeping your keys offline on the card. It even slips into a normal wallet alongside your bank cards.

Supported coins and features

The Arculus app does more than basic cold storage. It handles sending and receiving, plus token swaps, staking, NFTs and web3 connections, so it doubles as a light everyday crypto wallet as well as cold storage.

Coin coverage is the honest limitation. It handles Bitcoin, Ethereum and popular ERC-20 tokens well, but its list is focused rather than sprawling, and some major ecosystems such as Solana, Cardano and Avalanche have had limited support. If you hold a wide range of coins, check that your specific assets are supported before buying; if you hold mainstream ones, coverage is fine.

How the app and three-factor authentication work

The Arculus app is available for both iOS and Android, and it is where you store, send and manage your crypto. Its three-factor authentication, often shortened to 3FA, combines something you have (the physical card you tap), something you know (your PIN and phone passcode) and something you are (your biometric), so access to your funds needs all three.

For web3, the app connects to decentralized apps through WalletConnect, letting you reach DeFi or mint and hold an NFT while your key stays on the card. It is a rare mix of serious cold-storage security and everyday crypto convenience in one place.

Backup and recovery

Recovery is standard and reassuring. At setup the Arculus generates a normal BIP-39 recovery phrase, which you write down offline just as you would with any hardware wallet.

That matters because it means you are not locked to the card or the company: if the card is ever lost or damaged, you can restore your funds from the phrase. Treat that phrase with the usual care, offline and private, and the card itself becomes just a convenient key rather than a single point of failure.

The one real trade-off

The Arculus has no screen of its own. You review the recipient address and amount on your phone before you tap to sign, rather than confirming them on a separate device display.

For most people that is fine, especially with a clean phone. But it is a genuine difference from a Ledger or Trezor, where the isolated screen is a defense against malware that could alter what you see on the phone. If on-device confirmation of every send matters to you, a wallet with its own screen is the safer choice.

Arculus Wallet vs the alternatives

The comparisons that come up most are the other card wallet, the Tangem, and the classic USB devices from Ledger and Trezor.

In plain terms: the Arculus stands out for its three-factor tap and its metal build, the Tangem is the very simplest card to start with, and a Ledger or Trezor wins if you want an on-device screen and the widest coin support.

Price and value

At $99 the Arculus is priced with the affordable end of premium cold wallets, and for a metal, bank-grade card with three-factor security that is fair value.

• Worth it if you are a mobile-first user who wants strong, low-friction cold storage in a card.
• Consider the Tangem if you want the simplest possible card wallet, with a card-set backup.
• Consider a Ledger or Trezor if you want an on-device screen and the widest coin support.

One thing to note: the firmware and app are closed source, so it leans on certification rather than open-source scrutiny for trust, and it is mobile-only with no desktop app.

Who should buy the Arculus Wallet

• Mobile-first users who want cold storage without cables or a battery.
• Anyone who values three-factor security in a pocketable metal card.
• Holders of mainstream coins who do not need a long tail of niche assets.
• Beginners who want real security without complicated hardware.

It is less ideal if you want on-device transaction confirmation, hold coins outside its focused list, or prefer open-source firmware and a desktop app. For everyone else, this Arculus Wallet review lands where the score does: one of the cleanest, most approachable ways to take your keys off an exchange.
