Keys never touch the computer. Specter Desktop coordinates — your signing device holds the keys and confirms every transaction.

Your keys. Your node. Your bitcoin.

04Bitcoin Core

Run your own node.

Leverage Bitcoin Core as the foundation for a secure, private and verifiable setup. Rely on your own node to verify transactions and protect your privacy — no third-party servers in between.

No node handy? Connect to a node-in-a-box such as MyNode, RoninDojo, Raspiblitz or Umbrel — though Specter is optimized to run locally alongside Bitcoin Core.

05Multisig

Coordinate secure wallets.

Build a security model that matches the value and threat profile of your bitcoin. A multi-sig scheme offers a high degree of security; single-sig cold storage stays convenient for smaller amounts.

07Privacy / Tor

Privacy is part of the architecture.

Use Tor to anonymize connections and securely access your wallets. Enable the built-in quick setup or a custom configuration — or run Specter as a Tor hidden service and reach your node from anywhere.

Privacy by design.

08Air-gapped signing

Sign without exposing your keys.

PSBTs enable transactions to be created, transferred and signed without exposing private keys to the online environment. QR codes enable a fast and intuitive signing experience — SD cards and USB-connected devices are supported too.
