Why WallCard
Not another MetaMask moment
Browser wallet extensions solved early crypto adoption. WallCard solves the next problem: making wallet actions feel premium, familiar, and self-custodial for normal users.

Browser wallet extension
MetaMask-style popup flow
Install before trust
Users must add a browser extension before they can even try your product.
Popup fatigue
Every sign and send becomes a disconnected popup that breaks the flow.
Mobile web drop-off
Extensions do not travel cleanly to mobile browsers, where most users bounce.
Feels technical
Seed phrases and wallet jargon make mainstream users hesitate at the first step.
WallCard
Card-native wallet alternative
Card-first approval
People approve with card number, CVV, PIN, and OTP instead of learning wallet UX.
Self-custodial control
Nobody can sign without the cardholder. You stay in control of every move.
Works with existing dapps
Use WallCard inside the apps and flows people already know, without forcing another extension.
Premium banking feel
The experience feels like neo crypto banking, not a developer tool stuck in the browser.
The unique way
How WallCard works differently
You do not ask users to become wallet experts. You give them a premium card approval flow that still completes real wallet actions.
1
Open your app or dapp
Start from the product people already use. No extension install step.
2
Approve with your WallCard
Use the card flow users trust from everyday banking and e-commerce.
3
Sign or send on-chain
Complete wallet actions across Solana and Ethereum with one premium approval journey.
Social proof
Trusted by teams building on public chains
WallCard gives teams a stronger wallet and banking story: premium consumer experience, self-custodial control, and better trust at the point of approval.

How it works
From first card to everyday crypto banking
WallCard turns crypto into a premium banking experience without giving up self-custody.

2
Get your neo crypto card
Card, app, and wallet flow come together in one experience people already understand.
3
Use it with existing dapps
Move through familiar wallet journeys across the apps your customers already trust.
4
Approve every move yourself
Self-custodial signing stays in your hands, with clear visibility for every approval and send.
Compatibility
Works with the products people already use
WallCard feels native inside existing dapps and crypto apps while giving the experience a more premium, consumer-ready layer.
Built for real wallet behavior
WallCard is presented as a proper wallet alternative, not a payment gimmick or temporary bridge.
One premium identity
One account, one card, one app, one self-custodial experience across the crypto journeys people care about.
Works with existing products
Position WallCard inside dapps, consumer apps, and neo-banking experiences without retraining users.

Built for agents
Give your agent a card, not a private key
AI agents can propose on-chain actions without holding your keys. WallCard signs with email OTP, pushes large moves to slide-to-approve in the app, and keeps a live record of what every agent is doing.
Private key in the agent
Risky default
Private keys leak into context
Keys end up in prompts, logs, memory stores, and third-party tools. One mistake exposes the whole wallet.
No visibility into agent moves
When an agent holds a key, you cannot easily see what it signed, sent, or approved on your behalf.
All-or-nothing trust
Raw key access means every small action carries the same blast radius as a large treasury move.
WallCard for agents
Secure default
Email OTP signing
Agents release signatures with a one-time email code. The private key stays with WallCard, not inside the agent.
Slide to approve large moves
High-value transactions push to the WallCard app. You slide to approve on device before anything sensitive goes through.
Activity feed in the app
Every agent request shows up in Recent activity so you can track what ran, when it ran, and where it came from.
Self-custodial: nobody signs without your WallCard credentials
Three surfaces
OTP for speed. Slide for size. Activity for trust.
The same agent workflow can sign quickly with email OTP, pause big moves for slide approval, and leave a clean audit trail in the app.

Best practice
The secure way to let agents move on-chain
1
Give the agent a card identity
Connect WallCard instead of exporting a private key into agent memory or a shared vault.
2
Let routine actions use email OTP
Smaller agent moves sign through email OTP so automation stays fast without handing over key material.
3
Escalate large txs to the app
When a move crosses your risk threshold, WallCard sends push approval and you slide to confirm on your phone.
4
Review the activity feed
Open WallCard anytime to audit agent requests, origins, and approval status in one place.
