Free Open source Windows: Unverified v3.22.0.2-b2 Updated 14 May 2026
6 min read Last update 14 May 2026 github.com/mycelium-com/wallet-android

Wallet Android is a free, open-source crypto wallet for people who want to control their own Bitcoin keys instead of leaving funds with an exchange. It suits users who value transparency, care about hardware wallet support, and are ready to manage a seed phrase themselves. Its source code is public on GitHub, and the latest code update is dated May 14, 2026, so the project is actively maintained.

The current build is a release candidate, rc-3.22.0.2, and the documentation lists Windows alongside Linux, Android and Docker. The app was designed around Android, so anyone looking for Wallet Android for Windows should confirm that a desktop build exists before relying on it. Read the safety section before installing anything that touches your funds.

02

What Is a Non-Custodial Bitcoin Wallet?

A non-custodial wallet means you hold the private keys that control your coins. No company can freeze or move them on your behalf. Your balance is recorded on the blockchain, and the wallet app is the tool that signs transactions with your keys.

The trade-off is responsibility. If you lose your seed phrase and your device, there is no customer support desk that can restore access. That is why self-custody suits people who are willing to back up and store their keys carefully.

03

Who Wallet Android Suits Best

Wallet Android is most useful for people who already hold Bitcoin and want to move it out of exchange accounts. It also fits users who prefer to pair a phone-based wallet with a hardware device for signing.

Developers and technically curious users benefit from the public code. They can review it, follow its development, or compare its approach with other open-source wallets before trusting it with larger amounts.

04

How Hardware Wallets Fit Into a Mobile Wallet

A hardware wallet stores the signing keys offline. The companion app builds the transaction and sends it to the device, which confirms the details on its own screen. Your keys never leave the hardware.

This split is valuable when the phone or computer may be compromised. Always compare the amount and destination address on the device screen before approving a transfer, because the app display alone cannot prove what will be signed.

05

Key features

Open-source codebase

The app is written in Java and Kotlin, and its source code is public on GitHub. Developers and security-minded users can read how it works, report issues, or build the app themselves from the published code.

Hardware wallet compatibility

The wallet is documented to work with Ledger, Trezor and KeepKey devices. This lets you keep signing keys on a dedicated device instead of on your phone or computer, which reduces exposure to malware on the host.

Beta channel for faster updates

Users who want fixes sooner can enable beta versions of the software. The trade-off is that beta builds receive less testing than stable releases, so they suit people who accept some rough edges.
06

Supported coins

The documentation names Bitcoin (BTC) as the supported coin. Because the project centers on Bitcoin, check the official documentation for the current list before assuming support for any other currency. The SHA-256 algorithm appears in the project's technical profile as the mining algorithm of Bitcoin, which describes network mining rather than what the wallet does.

07

How to install Wallet Android on Windows

  1. 1

    Get the file from an official source

    Download the build only from the official website or the project's GitHub Releases page. Avoid third-party mirrors, repackaged installers and links shared in chats or ads, since they are a common way to distribute tampered software.

  2. 2

    Verify the checksum or signature

    Compare the file's SHA-256 checksum with the value published by the project, or check the signature if one is provided. Do not install a file that does not match exactly.

  3. Install and confirm Windows support

    Before installing on a PC, confirm in the documentation that a Windows build exists, since the app was designed for Android. Once installed, create a new wallet and write down the seed phrase on paper, not on a connected device.

08

How to use Wallet Android

Once the app is installed, the basic workflow is straightforward. The steps below assume you are starting with a new wallet.

  1. Create a new wallet and write the seed phrase on paper.
  2. Store the paper backup offline in a secure place, away from your device.
  3. Connect a hardware wallet such as Ledger, Trezor or KeepKey if you plan to use one.
  4. Check the receiving address on your hardware device screen before sending or receiving coins.
  5. Send a small test amount first, and confirm it arrives correctly before moving larger sums.
  6. Track updates through the project's official channels, and decide whether to enable beta builds.

Is Wallet Android safe?

Wallet Android handles private keys, so treat installation as a security task. Download only from the official website or the project's GitHub Releases page. Verify the SHA-256 checksum or signature before running the file, and never enter your seed phrase on any third-party website, form or support chat.

Because the current build is a release candidate, expect possible bugs and avoid storing large amounts until you have tested it with small transfers. The public code and recent updates are reassuring, but they do not replace your own precautions. Check the latest version on the official website before installing.

  • Official source only. Download from github.com/mycelium-com/wallet-android. Ignore ads and lookalike domains.
  • Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
  • Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.

Alternatives

Wallet Android differs from many alternatives in its focus. It centers on Bitcoin, pairs with hardware wallets, and is built around Android, with Windows listed in the documentation. Electrum and Sparrow Wallet are stronger choices for desktop Bitcoin users who need features such as Lightning, multisignature or detailed coin control. Cake Wallet and Stack Wallet suit people who want several currencies in one app. Wasabi Wallet focuses on CoinJoin privacy, and Electron Cash is the option for Bitcoin Cash. Pick the tool that matches the coins and workflow you actually use.
