Instead of complex wallet interfaces and confusing approval popups, WallCard gives you a simple, card-first experience that makes managing digital assets easier to understand.

Security and Ownership WallCard is built around a simple principle: your card, your keys, your assets. As a self-custodial wallet, you remain the owner of your wallet and digital assets at all times. WallCard does not take custody of your funds and cannot access, move, or control your assets on your behalf. PIN verification, biometrics, OTP verification, and approval requests act as security layers that help protect access to wallet actions while keeping you in control of every important decision. Security features include: • Self-custodial ownership of your wallet • PIN and biometric protection • OTP verification when required • Mobile approval notifications • Account and device management controls Powered by NodeRails Card Network WallCard is powered by NodeRails, a crypto payments and wallet infrastructure platform designed to simplify blockchain interactions for everyday users.

WallCard is designed for people who want the benefits of crypto without the complexity of traditional wallet experiences.
