What is Samourai Wallet? A Secure Bitcoin Wallet for Android
Samourai Wallet is a mobile wallet built specifically for Android. I use it because it treats Bitcoin as private cash, not a public ledger. Its tools are designed to actively protect your on-chain privacy during every transaction and its open-source wallet repository is a valuable resource. It's one of the few open-source wallets that makes advanced coinjoin mixing accessible on a phone; you can find the project's complete codebase, including for its atomic swap implementation, at https://code.samourai.io/wallet/comit-swaps-java. This secure crypto wallet’s development is transparent, and you cannot find the final application on the Google Play Store for important security reasons, which further underscores its commitment to user privacy and sovereign financial tools.
Core Privacy and Security Features of Samourai Wallet
Its privacy features are what set this Android wallet apart from generic crypto wallets. These tools work automatically after you configure them.
- Stealth Mode hides the app icon and opens with a PIN.
- Remote SMS commands let you wipe the wallet if your phone is taken.
- PayNym bots create reusable, non-reusable payment codes for receiving.
- VPN or Tor routing is built directly into the wallet's settings.
- Transaction broadcasting can be delayed to obscure timing analysis.
I rely on these because they create layered defenses. Stealth Mode alone has saved me from awkward explanations more than once. This focus makes it a true privacy wallet, not just a storage app.
How to Download and Install Samourai Wallet from Samourai.io
Since it's not on Google Play, you must get it from the official source. I always double-check the URL to avoid fake wallets.
| Brand | Source | Verification | My Verdict |
|---|---|---|---|
| Samourai Wallet | Samourai.io website | PGP signature check | Only safe source |
| Google Play Store | Official app store | Google's automated scan | Not available here |
| APK Mirror sites | Third-party repositories | MD5 hash comparison | Extreme risk, avoid |
Key Samourai Wallet Tools: Whirlpool, Ricochet, and Stonewall
These advanced wallet tools are why I recommend Samourai. Whirlpool is a coinjoin implementation that mixes your bitcoin with others for privacy. Ricochet adds extra decoy hops to a transaction for a small fee, making chain analysis far harder. Stonewall constructs a transaction with a peer to mimic a coinjoin, confusing observers. Using Whirlpool requires a separate coordinator fee, typically 0.001 BTC plus miner fees. These are not just features; they are essential privacy actions.
Step-by-Step Guide to Setting Up Your First Samourai Wallet
The initial wallet setup is critical for security. I always do this offline in a secure location. Write your 12-word backup phrase on paper, never digitally.
Your backup phrase is the wallet. The app is just a window. Lose the phrase, lose everything—no customer support can save you.
Comparing Samourai Wallet with Other Crypto Wallets
It occupies a unique niche. Here’s how it stacks up against other popular mobile wallets.
- Samourai: Privacy-first, Android-only, open-source, advanced tools like Whirlpool.
- BlueWallet: Multi-asset support, iOS & Android, user-friendly, Lightning Network focus.
- Electrum: Desktop powerhouse, highly customizable, complex for beginners.
- Trust Wallet: Binance-owned, supports thousands of altcoins, weaker Bitcoin privacy.
- Blockstream Green: Multi-sig security, good for hodling, less proactive privacy.
I choose Samourai for active Bitcoin spending. For pure, daily Bitcoin privacy, no other mobile wallet offers its specific toolset. If you need iOS or altcoin support, you must look elsewhere immediately.
Managing Wallet Releases and Staying Updated
You are your own security manager. Wallet updates contain critical fixes and new features.
| Update Method | Frequency | Your Action Required | Risk if Skipped |
|---|---|---|---|
| Major Release | ~Every 6 months | Manual APK download & install | High |
| Minor Patch | ~Monthly | Manual APK download & install | Medium |
| Coordinator Update | As needed | None, server-side | Low |
Advanced Configuration and Open-Source Code Review
The real power lies in its advanced settings. I connect Samourai to my own Bitcoin Core node using Electrum Personal Server. This means my wallet queries my own private copy of the blockchain, not a third-party server. The code is open-source and available on their GitHub repository for public audit. This self-sovereign setup is the gold standard, removing all third-party trust from your wallet's view of the network. It requires technical effort but maximizes privacy and security.

The developers removed it for security and privacy reasons. You must download the APK directly from the official Samourai.io website and verify its PGP signature.
Can I use Samourai Wallet on an iPhone?
No, it is an Android wallet only. For iOS, you would need to consider a different privacy-focused Bitcoin wallet like Blockstream Green or BlueWallet.

Follow their official Telegram channel or check Samourai.io. All updates require a manual APK download and installation from their site.
What's the purpose of the Whirlpool tool?
Whirlpool is a coinjoin implementation that mixes your bitcoin with others to break the transaction trail on the blockchain. It requires a coordinator fee to use.
Should I store all my bitcoin in Samourai?
I use it for daily spending, not long-term storage. For significant savings, send mixed coins to a hardware wallet like a Coldcard for maximum security.
