The APK passes v2/v3 signature verification. Check both the file hash and the certificate fingerprint. A matching hash or valid signature does not establish production wallet security.

02 / TEST SCOPE

Mock assets. No real transactions.

What you can explore

Home, Assets, History and Settings.
Local Mock Send, Review and Success flows.
A TEST ONLY receive identifier, copying and Android sharing.
Light and dark themes.

Important limits

All balances, history and send results are simulated.
The demo receive identifier cannot receive funds.
Real wallet creation, import, key storage and transactions are unavailable.
Security settings are interface previews.

Production Ready: NO. An independent production security audit has not been completed. Minimum OS support does not mean every device has been tested.

03 / INSTALLATION

Install with care

Confirm the official MDC HTTPS domain and GitHub repository owner before downloading. Avoid ads, unsolicited attachments and repackaged files.
Compare the downloaded APK's SHA-256 with this page and the matching GitHub Release. Stop if any value differs.
If Android asks to allow installation from your browser or file manager, grant permission only after checking the source. Turn that permission off after installation. Keep Play Protect enabled and do not bypass a blocked installation.
Confirm the app name includes DEMO and the screens clearly identify simulated or TEST ONLY content. Stop if the app asks for real secrets or transfers.

Use a spare device for initial testing where possible. Do not uninstall an existing wallet or clear its data to resolve a signature conflict. Check the package ID, version and signer before installing an update.

Verify the APK on Windows

Get-FileHash -Algorithm SHA256 -LiteralPath '.\mdc-wallet-demo-signed.apk'
apksigner verify --verbose --print-certs '.\mdc-wallet-demo-signed.apk'

The second command requires Android SDK Build Tools on your command path. Verification must succeed and the certificate SHA-256 must match the value above.

04 / PRIVACY

For this offline DEMO only

The reviewed APK requests no Android permissions, including INTERNET, and has no configured developer analytics, advertising or remote crash-reporting service. It does not connect to a public blockchain.

Copying writes TEST ONLY demo text to the system clipboard. Sharing opens Android's share sheet. Android, device vendors, keyboards and receiving apps may process information under their own practices. Website and hosting providers may process access logs.

Responsible team: Dapp developer team. Contact: contact@mdctoken.org. Read the privacy policy for support-email retention and deletion details. Never email secrets.
