Product Description: Air-Gapped Multisig Starter Kit

Secure your crypto assets at the highest level with the Air-Gapped Multisig Set. By combining three different hardware wallets, you can effortlessly set up an ultra-robust 2-of-3 recovery structure. Because the devices come from different manufacturers, you completely eliminate the risk of system failures, firmware bugs, or hardware defects from a single vendor.

This bundle operates entirely air-gapped—none of the devices ever connect directly to the internet. Transactions are signed 100% offline via dynamic QR codes, fully compatible with management software like Sparrow Wallet.

What's in the Box?

Three high-quality Bitcoin-compatible hardware wallets, each featuring a spacious color screen for smooth offline QR interaction:

• Foundation Passport Prime: A robustly designed, Bitcoin-only wallet with an intuitive 3.5-inch touchscreen for offline signing.
• Keystone 3 Pro: Equipped with a crisp HD display and an integrated camera, specifically engineered for a fast and secure QR workflow.
• OneKey Pro: A powerful hardware wallet featuring a large display, a secure element chip, and broad support for open standards.

Why Choose the Air-Gapped Set?

• Complete Physical Isolation: No USB cables or Bluetooth connections required. Your private keys never touch a compromised computer or online network.
• Optimal Interoperability: All three wallets process the universal PSBT standard (Partially Signed Bitcoin Transactions) and work seamlessly together within Sparrow Wallet.
• Instant Visual Verification: Review and verify receiving addresses and transaction amounts on the large device displays before signing off.

Select Your Package Variant:

Option 1: Standard Set

Includes the 3 air-gapped hardware wallets (Passport Prime, Keystone 3 Pro, and OneKey Pro) along with our comprehensive, step-by-step Multisig Setup Guide.

Option 2: Standard Set + 3 Metal Backups (Bundle Value)

Includes 1x SOLIDHODL Pack + 2x SOLIDHODL Plate

A multisig setup is only complete when the recovery words (seed phrases) of all three devices are protected against extreme physical damage. With this upgrade, you protect your physical keys under any conditions:

• 3x AISI 316 Stainless Steel Plates: Plenty of surgical-grade stainless steel to permanently log the seed phrases for every wallet in the kit.
• Extreme Durability: Resistant to fire (up to 1300°C / 2370°F), water, acids, and saltwater corrosion.
• Bundle Savings: Get maximum savings by ordering the steel backup plates together in one complete kit.

Specialist Tip: In a 2-of-3 multisig setup, each wallet generates its own unique seed phrase. Make sure to store the three steel backups in three separate physical locations after setup.
