Sparrow on Linux.

Quick Start

Install, verify, then create or connect a wallet.

1. Go to the downloads section and choose the Linux package format you need.
2. Download the package and its signature file.
3. Verify the signature before running the installer.
4. Open Sparrow and connect to Bitcoin Core, your Electrum server, or a public server for first setup.
5. Create a new wallet, import an existing seed, or connect a hardware wallet.

Installation Guide

Choose the package that fits your distro.

Use .deb for Debian or Ubuntu based systems. Use .rpm for Fedora style systems. Use .tar.gz or .AppImage when you want a portable install path.

# Debian / Ubuntu
sudo dpkg -i sparrow_*.deb

# Portable tarball
tar -xzf sparrow-*.tar.gz
cd sparrow-* && ./bin/Sparrow

The Linux builds bundle their runtime, so a separate Java install is normally not needed.

Verification

Verify downloads before running them.

Keep the application file and the matching .asc signature in the same folder, then verify the release with GPG.

gpg --verify sparrow-*.tar.gz.asc sparrow-*.tar.gz

If verification fails or the file names do not match, do not run the download. Fetch a fresh copy from the downloads section.

Best Practices

Use Sparrow as a self-custody tool, not just a balance screen.

• Prefer a hardware wallet for meaningful funds.
• Back up seed words offline and test recovery before relying on the wallet.
• Run your own node or private Electrum server when privacy matters.
• Use coin control and labels so future spending decisions are clear.
• Verify every address on the signing device when using hardware wallets.

Changelog

Local release notes placeholder.

This section is ready for condensed release notes when the project starts publishing them locally. For now, use the downloads section as the canonical entry point and keep verification enabled for every update.
