Specter Desktop v2.0.2

Specter Desktop is a graphical application that sits on top of a personal Bitcoin Core node and coordinates wallets protected by signing devices. It focuses on multisignature setups, where several hardware wallets each hold one key in a shared scheme.

Transactions are built as partially signed transactions and can be approved over QR codes, SD cards, or USB, so keys never have to be exposed on the connected computer. Wallet backups can be exported as PDF or JSON files and stored next to the recovery words.
