Arculus is a cold wallet designed to store private keys offline on a secure element inside a metal card. Arculus uses 3-factor authentication (biometric, PIN, and card tap) to protect access and approve transactions.
Learn the risks of exchanges and hot wallets, how cold wallets work, and why Arculus makes secure self-custody simple.
Arculus uses three factors together.
A wallet is only as safe as the behavior it can sustain.
Three Practical Components of Safe:
Security is not only specs. Security is also usability.
Convenient, but a third party controls custody and availability.
Convenient, but connected to the internet and exposed to phishing and malware risk.
Designed to keep private keys offline and require physical presence plus authentication for transaction approval.
Many hardware wallets provide strong security, but the experience can be hard for first-time users. That friction is where people abandon cold storage.
