Stake DUAL with your Tangem card.
The Tangem app does not yet support custom EVM networks, so it cannot reach the Dual Network for staking. We built a dedicated app that connects a Tangem card to the Dual staking interface. It is an independent tool, not an official partnership, and it stays in place only until the Tangem app supports the Dual Network directly.
Complete a small test stake before committing your full amount, to confirm your phone is compatible and everything runs smoothly. The app has been tested thoroughly, but each phone is different, and it remains a workaround until the Tangem app officially supports Dual Network.
This app is published by Intern Labs, Inc. and built for the Dual community to stake with a Tangem card. It is an independent tool, not affiliated with, endorsed by, or in partnership with Tangem. “Tangem” is a trademark of its respective owner, as are Apple, Android, and Google Play. Your keys never leave your card. Use the app at your own discretion. Neither Dual Foundation nor Intern Labs, Inc. is liable for any losses arising from use of the app.
Why a separate app is necessary.
The Dual Network is a custom EVM Layer-2. The Tangem app does not let you add it manually, so there is no way to sign Dual staking transactions from Tangem alone. This app provides that path while the limitation remains.
Tangem does not support custom networks
Tangem supports a fixed list of chains and does not allow adding a custom EVM network. Without that option, the Dual Network cannot be reached for signing inside the Tangem app.
Your card keeps custody
The app never accesses your seed phrase. Every transaction is signed on the Tangem card over NFC, exactly as it is anywhere else.
A temporary solution
This app is for community members who have already bridged their tokens to the Dual Network and need a way to stake them. Once the Tangem app supports the Dual Network, you can stake from Tangem directly and the app is no longer needed.

How to install on Android.
The app installs outside the Play Store, so Android will ask you to approve it once. The steps below cover the full process.
Open the install link
Tap Download Android App on your Android phone, sign in with a Google account, and accept the tester invitation. This gives you access to the latest build.
Install through App Tester
Firebase offers its App Tester app, which lists the build and notifies you of future updates. Open it and tap Download on DUAL Staking Wallet. You can also download the APK directly from the browser.
Allow installs from unknown sources
Because the app is not from the Play Store, Android asks you to approve it once. When prompted, allow installs from App Tester or your browser, then confirm. You can turn the permission back off afterward.
Scan your Tangem card and stake
Open DUAL Staking Wallet, hold your Tangem card to the back of the phone to connect, then stake at staking.dual.org inside the app. Every transaction is signed on the card.
