Description

Arculus Cold Wallet is a sleek metal card that secures your digital assets through 3-factor authentication via NFC tap. Combining your biometrics, a secret PIN, and the card itself, it provides institutional-grade cold storage that's as easy to use as a hot wallet.

3-Factor Authentication (3FA)

  • Something You Are — Your unique biometrics (fingerprint or face unlock) authenticate access via your mobile device.
  • Something You Know — A secret personal identification number (PIN) chosen by you provides the second layer of defense.
  • Something You Have — The Arculus Card itself, which encrypts your private keys on a secure element embedded in the metal card.

Security & Design

  • Premium Metal Card — Sleek, durable, and slim enough to fit in your physical wallet alongside your other cards.
  • Secure Element Chip — Private keys are generated and stored inside the card's embedded secure chip and never leave it.
  • NFC Tap to Sign — Simply tap the card to the back of your NFC-enabled phone to sign transactions — no cables, dongles, or Bluetooth required.
  • No Batteries Needed — Powered entirely by your phone's NFC field.

Supported Assets

Supports over 95% of crypto assets by market capitalization — 10,000+ coins and tokens across 50+ blockchains. Custom tokens can be added manually.

Web3 & DeFi Integration

Connect to your favorite DeFi platforms and Web3 apps using MetaMask or WalletConnect. Send, swap, and purchase crypto and NFTs with ease.

The Arculus App

Available on iOS and Android, the Arculus App provides a seamless interface for managing your portfolio, viewing balances, and initiating transactions — all secured by your card.
