CryptoSafe Vault is a Faraday box lined with metal on every side. Close the lid and wireless signals cannot get in or out. The interior is sized for hardware wallets and holds several at once, along with charging cables, backup cards and other small items. The outside is PU leather with a carbon fiber texture and red stitching, so it looks at home on a desk or in a drawer. Sold as a single box. Some photos show two angles of the same box.

How it works

The walls and the lid are lined with metal all the way around. With the lid shut, radio waves from outside cannot reach what is inside, and signals from inside cannot get out. This is called a Faraday cage. It is purely structural: nothing to plug in, nothing to charge, and no parts that degrade over time.

What it blocks

• Bluetooth no pairing or connection can happen while the lid is closed
• NFC cards and devices cannot be read at close range
• RFID contactless payment cards, building access cards, toll tags
• Car key signals stops relay and amplification attacks
• WiFi and GPS

Why blocking signals matters

Devices that communicate wirelessly, such as Tangem over NFC or Bluetooth models like the Ledger Nano X, Trezor Safe 7 and SafePal X1, cannot make any wireless connection while they sit inside this box. Nothing is read, nothing pairs, nothing is transmitted.

The same applies to modern car keys, which keep broadcasting even while they hang untouched. Thieves stand at the front door with a relay device, pick up the signal from the key inside the house, and unlock and start the car without ever holding it. Keep the key in this box and the signal never leaves, so that method has nothing to work with.

What fits inside

The interior measures 10.2 x 7.2 cm and is 4 cm deep. We measured it against the products we actually stock.

Frequently asked questions

How many hardware wallets fit?
The interior is 4 cm deep and devices stack. Most wallets are under 1 cm thick, so several go in comfortably together with cables and backup cards.

Does this box make my assets safer?
What the box does is block signals and keep things out of sight. The safety of your assets still rests mainly on your PIN and your recovery phrase. It is not a substitute for storing that phrase properly.

Does the latch take a key?
No. It is a catch that holds the lid firmly shut so the lining seals properly, not a lock against forced entry.

Does it need a battery or power?
No. The box works through its own construction. There is nothing to charge and nothing to replace.

Will a phone fit?
The interior is 10.2 cm long and most phones are longer, so no.

Can I test the shielding myself?
Yes. Put your car key inside, close the lid fully, and try to unlock the car.

One rule to remember

Anyone who asks for your recovery phrase is a scammer. No exceptions.

Neither SIAMBC nor any wallet manufacturer will ever ask for it, whatever reason is given: warranty claims, identity verification, firmware updates or account recovery. Those words are the key to your funds. Whoever has them owns your money, and it can never be recovered.
