Description
The Single-Signature Package is everything you need to run Bitcoin the sovereign way: verify with your own node, sign with two air-gapped devices, and back up your seed in steel. The Start9 Server One arrives with StartOS preinstalled. Plug in Ethernet, open a browser, and Bitcoin Core is syncing within minutes, no command line required. Pair it with Sparrow Wallet and your wallet verifies every transaction against your own copy of the blockchain instead of trusting someone else’s server.
The Jade Plus handles daily signing over air-gapped QR codes, while the SeedSigner+ serves as your stateless backup signer and seed generation tool, with dice included for provably random entropy in your own hands.
What’s Included
Full Node
- 1 x Start9 Server One: AMD Ryzen 5, 16GB LPDDR5 RAM, 2TB NVMe, StartOS preinstalled, Gigabit Ethernet, 2 year manufacturer’s warranty plus lifetime Start9 support
Two Signers, Two Vendors
- 1 x Blockstream Jade Plus (Lunar Silver, Metal): Premium metal hardware wallet with 1.9 inch display, QR camera, 280 mAh battery, and Genuine Check verification
- 1 x Blockstream JadeLink: 64GB USB-C drive for fully air-gapped signing and offline firmware updates
- 1 x SeedSigner+: Open-source, stateless QR signer with no WiFi or Bluetooth hardware. Holds no key material when powered off. Fully assembled in the USA.
Steel Backups
- 1 x Bitcoin Seed Phrase Backup Kit (3 plates total): Hardened stainless steel plates with electric engraving pen and locking screws, 12 or 24 word BIP39
Entropy, Distribution, and Setup Tools
- 10 x 6-sided casino dice
- 2 x 16-sided dice
- 1 x 8-sided die
- 9 x tamper-proof seal bags
- 2 x microSD cards
- 1 x SD card reader
Why This Package
- Your own full node: Verify everything, connect wallets privately, and expand into Lightning, BTCPay Server, Mempool, and 100+ services in the StartOS Marketplace.
- Two independent signers from two vendors: Both fully open source, both air-gapped by QR code. The Jade Plus is your daily driver. The SeedSigner+ restores the same seed if the Jade is ever lost or damaged, and holds nothing when powered off.
- Three steel plates: Redundant fireproof, waterproof backups of your seed, stored in separate locations. No single fire, flood, or break-in takes your backup with it.
- Dice entropy: Generate your seed on the SeedSigner+ from physical rolls in your own hands, not a chip you cannot audit. A 6-sided die yields 2.58 bits per roll, so 99 rolls produce a full 24 word seed. With 10 casino dice, that is 10 throws. The 16-sided dice provide exactly 4 bits per roll for an independent cross-check.
- Tamper-proof seal bags: Nine bags cover both signers, the JadeLink, all three steel plates, and spares for microSD cards, so you can seal every device and backup before storing it. Any attempt to open a bag leaves permanent evidence. Record each bag’s serial number before storage and verify it on every visit.
Don’t trust, verify. This is the complete stack to do it.
