Don't trust. Verify.
Bring your signing device.
Connect the hardware wallet that fits your security model. All common signing devices are supported — the list keeps growing.
Keys never touch the computer. Specter Desktop coordinates — your signing device holds the keys and confirms every transaction.
Your keys. Your node. Your bitcoin.
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.
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.
Multiple signing devices, coordinated signing, hardware-backed security. Lose one device — your bitcoin stays recoverable.
Control your coins. Control your privacy.
Use coin selection to spend from specific UTXOs and control your on-chain visibility. Freeze or unfreeze specific UTXOs, label everything, and fine-tune each transaction for quick confirmation or minimal fees.
Know exactly where your bitcoin is going.
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.
Run Specter as a Tor hidden service and access your wallets securely from anywhere.
Add an extra layer of security and password-protect your Specter wallets for remote access.
Privacy by design.
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.
Sign offline. Stay sovereign.
Own your backup.
Your wallet data should never be trapped inside one application. Interoperable standards mean you are free to choose — and your funds stay accessible even without Specter Desktop.
Export a PDF backup and keep it with each device and seed-word backup — especially for multisig wallets.
Export a JSON file of an individual wallet with complete data, including UTXO labels.
A .zip export of your complete Specter Desktop configuration: all signing devices and all wallet data.
Import wallets from Electrum, Fully Noded, Sparrow or another Specter instance — and export back out again.
Free.
Open source.
Verifiable.
Specter Desktop is FOSS — free open-source software under the MIT license. Everyone has the freedom to review, use and improve the code. Nothing to take on faith.
Your bitcoin shouldn't depend on one interface.
Specter supports interoperable wallet standards, so wallets move freely between software. Import from Electrum, Fully Noded, Sparrow Wallet or another Specter instance — and export just as easily.
One interface. Every network.
Liquid, Testnet, Regtest and Signet are supported alongside Bitcoin mainnet.
