Prerequisites: What You Need Before Installing Wasabi Wallet 2.0

Before diving into the installation, make sure your Linux system meets the following requirements:

Operating System: Wasabi Wallet 2.0 supports most modern Linux distributions, including Ubuntu, Debian, Fedora, and Arch Linux. Ensure your system is up to date.
Dependencies: You’ll need mono (for .NET runtime) and libgtk-3-0 installed. These are typically available in your distro’s package manager.
Tor Browser: Wasabi Wallet routes all transactions through the Tor network by default. Install Tor Browser or ensure the Tor service is running on your system.
Disk Space: Allocate at least 2GB of free space for the blockchain data and wallet files.

To check if mono and libgtk-3-0 are installed, run the following commands in your terminal:

Method 1: Installing via AppImage (Recommended for Most Users)

The easiest way to install Wasabi Wallet 2.0 is using the AppImage format, which doesn’t require root access or complex dependencies.

Download the AppImage: Visit the official Wasabi Wallet website and download the latest .AppImage file for Linux.
Make the File Executable: Open a terminal in the download directory and run:

```
First Launch Setup: On startup, Wasabi will prompt you to choose a data directory. Select a location with sufficient space for the blockchain.

Method 2: Installing via .deb or .rpm Package

If you prefer a traditional package manager installation, Wasabi provides .deb and .rpm packages for Debian/Ubuntu and Fedora/RHEL-based systems, respectively.

Download the Package: Get the appropriate package from the official website.

Install the Package: Use your package manager to install it. For example:

sudo dpkg -i wasabi-wallet-*.deb  # For Debian/Ubuntu
sudo rpm -i wasabi-wallet-*.rpm  # For Fedora/RHEL

Resolve Dependencies: If you encounter missing dependencies, run:

sudo apt --fix-broken install  # For Debian/Ubuntu
sudo dnf install -f             # For Fedora

Launch Wasabi: After installation, launch Wasabi from your application menu or terminal.

Method 3: Building from Source (For Advanced Users)

If you want the latest features or prefer compiling from source, follow these steps:

Clone the Repository: Run:

git clone https://github.com/zkSNACKs/WalletWasabi.git
cd WalletWasabi

Install Build Dependencies: Install dotnet-sdk-6.0 and other required tools. For example, on Ubuntu:
```
sudo apt install dotnet-sdk-6.0
```

Build and Run: Execute:

dotnet publish -c Release -r linux-x64 --self-contained false
cd Wasabi.Wallet/bin/Release/net6.0/linux-x64/publish

Configuring Wasabi Wallet 2.0 for Maximum Privacy

Once installed, Wasabi Wallet 2.0 offers several privacy-enhancing features. Here’s how to configure them:

Enable Tor Integration

Wasabi routes all traffic through Tor by default, but you can verify and customize the settings:

Go to Settings > Network.
Ensure Tor is selected as the proxy.
If you’re using a custom Tor configuration, enter the SOCKS5 proxy details (e.g., 127.0.0.1:9050).

Use CoinJoin for Enhanced Privacy

CoinJoin is Wasabi’s signature feature, allowing you to mix your coins with others for improved anonymity. To use it:

Navigate to the CoinJoin tab.
Select the coins you want to mix and click Start.
Adjust the Anonymity Target (e.g., 54) to balance privacy and fees.
Wait for the process to complete. This may take several hours depending on network conditions.

Enable RPC and Custom Backends (Optional)

For advanced users, Wasabi supports custom Bitcoin backends via RPC. To configure this:

Go to Settings > Bitcoin.
Enter the RPC credentials for your Bitcoin node (e.g., 127.0.0.1:8332).
Ensure your node is synced and running.

Troubleshooting Common Issues

Even with a smooth installation, you might encounter a few hiccups. Here’s how to resolve them:

Wasabi Won’t Start or Crashes on Launch

Check Dependencies: Ensure mono and libgtk-3-0 are installed. Reinstall them if necessary.
Clear Cache: Delete the ~/.config/wasabi directory and restart Wasabi.
Run in Terminal: Launch Wasabi from the terminal to see error messages:
```
./Wasabi-*.AppImage
```

Tor Connection Issues

Verify Tor Service: Ensure Tor is running:
```
sudo systemctl status tor
```
Check Proxy Settings: In Wasabi, go to Settings > Network and verify the Tor proxy address.
Use Bridges: If Tor is blocked in your region, configure bridges in the Tor Browser settings and update Wasabi’s proxy settings accordingly.

Slow Blockchain Sync

Use a Custom Backend: Connect Wasabi to your own Bitcoin node for faster sync times.
Enable Pruning: In Bitcoin Core, enable pruning to reduce storage usage:
```
prune=550
```
Check Internet Connection: A slow or unstable connection can delay syncing. Test your speed and switch networks if needed.
