Secure Wallet Access — Demo

Demo interface for connecting a hardware wallet or using a secure passphrase. This is not an official provider page.

Connect your wallet

How this login works (concept)

For a hardware-wallet login, the web app requests a cryptographic challenge from the server. The hardware device (via USB / WebHID / WebUSB / WebAuthn) signs that challenge with a key that never leaves the device. The server verifies the signature and grants access. No private keys or recovery seeds are ever sent to the server.

Security best practices

Always use TLS (HTTPS) and HSTS on the server.
Authenticate using challenges and device-resident keys (WebAuthn is preferred where available).
Never ask users to paste or upload their recovery seed or private key.
Display clear device prompts so users confirm transactions on the hardware device itself.
Implement rate limiting, anomaly detection and phishing-resistant UI patterns.

Warning: Do not copy this template and use it as an official page for any wallet provider. Impersonation and credential collection constitute fraud and can harm users. Always clearly identify your project and include legal / privacy notices.

Developer notes

When turning this template into a real integration, consider:

Using WebAuthn for attested resident keys or conditional UI.
Performing server-side validation and checking device attestation.
Logging only non-sensitive telemetry and storing nothing that could reconstruct user keys.
Providing copy & UI that educates users about verifying the device display for addresses and transaction details.

User guidance

If you are a user: always verify the URL, check your device's display for any unexpected prompts, and keep your recovery phrase offline and secure (preferably on paper or a hardware backup device).
