Start9 Labs
Jul 19, 2022


Today we are excited to announce Specter as the latest addition to the Start9 Service Marketplace! You can view the source code here.


Specter is a user-friendly web GUI for Bitcoin Core with a focus on multisignature setup with hardware wallets and airgapped devices.

At the moment Specter works with all major hardware wallets including:

  • Trezor
  • Ledger
  • KeepKey
  • BitBox02
  • ColdCard (optionally airgapped, using an SD card)
  • Electrum (optionally airgapped, if running Electrum on an airgapped computer/ phone)
  • Specter DIY (optionally airgapped, using QR codes)
  • Cobo (airgapped, using QR codes)

Specter also supports using Bitcoin Core as a hot wallet, by importing or generating a random BIP39 mnemonic, but this feature is experimental and not generally recommended.
