Android · beta
Dark is an Android app, downloaded from this site. There is no app-store listing, so check the file before you install it: it takes a minute and is the only thing standing between you and a copy someone else built.
01 · Get the app
Requires Android 9 or later. This page is the only place Dark is published. We will never send you the app in a message, an email or a direct link from anywhere else, and a file from any other source is not ours, whatever it is called.
02 · Check the file
The file checksum proves the download was not altered. The signing fingerprint proves who built it: only we hold the key that produces it, and Android refuses an update signed with any other.
File SHA-256
Published with the first release.
Signing certificate SHA-256
Published with the first release.
Run shasum -a 256 dark.apk (macOS or Linux) or certutil -hashfile dark.apk SHA256 (Windows) and compare the result with the file SHA-256 above. With the Android SDK installed, apksigner verify --print-certs dark.apk prints the signing certificate's SHA-256.
If either number differs, delete the file.
Do not install it, and do not enter your recovery phrase into it. Tell us at team@darkwallet.cash.
03 · Install
Open the downloaded file. Android asks you to allow installs from your browser or file manager; allow it, install Dark, then switch the permission back off. Later updates are checked against the same signing key, so a replacement signed by anyone else will not install over it.
04 · iPhone and web
There is no iPhone app yet. The web wallet (beta) is at darkwallet.cash/app and nowhere else. You connect MetaMask or another browser wallet, and your keys never leave your device. If you find Dark anywhere else, it is not Dark.
On iPhone (iOS 17 or later), open darkwallet.cash/app in Safari, tap Share, then Add to Home Screen. On a computer, open it in Chrome and choose Install in the address bar. While you use it, a reload or reopen needs no new signature: the key is kept encrypted on your device for up to 24 hours after your last use. Fifteen minutes without input locks it, and Lock forgets it at once.
