WallCard

WallCard is a self-custodial crypto wallet designed to feel as familiar as using a traditional debit/credit card.

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.

Your wallet address works like an account number for receiving funds, while PINs, biometrics, OTP verification, and approval prompts help secure wallet operations and keep you in control of your assets.

With WallCard, you can:

• View your balances from a clean, intuitive dashboard
• Send and receive assets with simple confirmation flows
• Review wallet activity and transaction history
• Approve requests from connected apps directly from your phone
• Manage security settings in one place
• Access multiple blockchain networks through a familiar experience

Built for the modern Web3 ecosystem, WallCard helps simplify interactions with decentralized applications, connected services, and AI-powered agents without sacrificing user control.

Unlike traditional wallets that often expose users to complex signing flows, WallCard presents approvals in a clearer and more understandable way, helping users make informed decisions before taking action.

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

WallCard is powered by NodeRails, a crypto payments and wallet infrastructure platform designed to simplify blockchain interactions for everyday users.

NodeRails acts as the network and infrastructure layer behind the WallCard experience, helping connect wallets, applications, payment flows, and approval systems through a unified card-first model.

By combining self-custody with familiar payment experiences, NodeRails and WallCard make digital assets more accessible without compromising user ownership and control.

WallCard is designed for people who want the benefits of crypto without the complexity of traditional wallet experiences. Whether you're managing assets, interacting with apps, or approving transactions, WallCard provides a simpler and more familiar way to stay in control.
