Specter Desktop: Multisig Bitcoin Wallet Coordinator

Specter Desktop is a coordinator: it does not hold your private keys itself. Instead, it helps you build and use wallets whose keys live on hardware wallets, including multisignature wallets that need several devices to approve a payment.

What Specter Desktop does

• Hardware wallet support: Use devices from several manufacturers, connected by USB or through QR codes and files for air-gapped devices.
• Multisig setups: Combine keys from different devices so no single lost or stolen device can move your coins.
• Your own node: Connect to Bitcoin Core or an Electrum server, so your balance checks do not depend on a third party.
• Two ways to run it: A desktop app, or specterd, a server version you open in a browser, also available as a Docker image.

Download

The Download button opens the official GitHub releases page, which lists:

• Windows: an .exe installer.
• macOS: a .dmg app.
• Linux (x86-64): a .tar.gz app.

Make sure you pick the latest stable release, not a pre-release, unless you want to test new features.

Multisig needs careful backups

A multisig wallet needs more than seed phrases: you also need the wallet configuration (the “descriptor”), or you may not be able to rebuild it. Specter can export a backup; keep copies with each device’s recovery phrase. Practice with a small amount before moving savings.

If you do not run a node yet, umbrelOS is one way to set one up at home. Specter Desktop is open source under the MIT license.
