Return and Exchange Policy
Faulty on arrival: if a device arrives defective — a broken screen, a connectivity fault — we replace it with a new one straight away. No forms, no waiting on the manufacturer.
Warranty: hardware wallets carry a 1-year warranty, and claims are handled by us rather than an overseas support queue. CryptoSafe steel backup products are sold without warranty, as stated on those product pages.
Change of mind or wrong model: we do not accept returns or give refunds, whether or not the box has been opened. We accept returns for defective products only, which we exchange within 30 days of delivery. This is a security limitation of these devices: once a device has left us, we cannot assure the next customer that it has not been interfered with.
How to arrange an exchange for a faulty item
- Message us on LINE at @siambc or email order@siambc.com before sending anything back.
- Include your order number, what is wrong, and a photo or short video.
- Send the item back to us at your own shipping cost. Once we have checked it, we exchange it.
Refunds: faulty items are exchanged rather than refunded.
Pairs well with
Blockstream Jade is a Bitcoin-only hardware wallet built by Blockstream, one of the longest-standing engineering teams in Bitcoin. It is 100% open source in both firmware and hardware, which almost no other wallet can claim.
Bitcoin and Liquid only, on purpose
Jade supports Bitcoin and Liquid assets and nothing else. If you only hold Bitcoin, that focus is a feature: less code means fewer places for something to go wrong, and the firmware is built by people who work on Bitcoin infrastructure full time.
How Jade secures your keys
Jade uses what Blockstream call a Virtual Secure Element, built on blind oracle encryption. It allows the device to remain fully open source while resisting physical key extraction — Blockstream describe it as simulating the protection of a secure element in software rather than a dedicated chip.
That is a deliberate design choice: secure element chips are proprietary and cannot be fully audited, so Blockstream chose transparency instead. It is a different security philosophy, not a weaker one — and it is the reason Jade can claim to be fully open source.
Security features
- 100% open source firmware and hardware, fully reviewable
- Air-gapped QR signing — scan and display QR codes directly on Jade, with no USB or Bluetooth connection required
- Anti-Exfil signatures, which prevent a compromised device from leaking your key through the signatures it produces
- Dice-roll entropy — add your own physical randomness when generating your recovery phrase
Specifications
- Color display with a camera for QR scanning
- USB-C and Bluetooth
- 60 x 24 x 17 mm, 21 g
- 240 mAh battery
- Plastic body
Backup and compatibility
- 12 or 24-word recovery phrase, or recovery by QR scan
- Blockstream app: Android over Bluetooth or USB-C, iOS over Bluetooth, desktop over USB-C
- Also works with BlueWallet, Electrum, Nunchuk, Sparrow, Specter and HWI
Common questions
Does it have a secure element?
Not a dedicated chip. Blockstream uses a Virtual Secure Element built on blind oracle encryption, which keeps the device fully open source while resisting physical key extraction.
Can I store Ethereum or other coins?
No. Jade is Bitcoin and Liquid only, by design.
What is Anti-Exfil?
A signing method that stops a tampered device from hiding your private key inside the signatures it produces. It is a genuine advantage and rare in this price range.
What is dice-roll entropy?
You can add randomness from physical dice when creating your recovery phrase, so you are not relying solely on the device's own random number generator.
Can I use it with an iPhone?
Yes, over Bluetooth with the Blockstream app.
Buying from SIAMBC
SIAMBC is Thailand's authorized Blockstream distributor, with a physical store in Bangkok. Every unit is new, sealed and sourced directly. Support is available in Thai and English.
ONE RULE TO REMEMBER
Anyone who asks for your recovery phrase is a scammer. No exceptions.
Neither SIAMBC nor Blockstream will ever ask for it, whatever reason is given — warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds. Whoever has them owns your crypto, and it can never be recovered.

Blockstream Jade FAQ
How much is the Blockstream Jade?
3,190 ฿ at SIAMBC, the authorized Blockstream reseller in Thailand.
What does it support?
Bitcoin only, including assets on Liquid, a Bitcoin layer 2. It does not support Ethereum or any other network.
Does it work with an iPhone?
Yes. The Blockstream app on iPhone connects to Jade over Bluetooth only; there is no cable connection.
Can I verify it with Genuine Check?
No. Genuine Check is only on Jade Plus and Jade Core. For this model, follow "How to check your device is genuine" above.
Can it update firmware without a connection?
No. Updating from a USB drive is a Jade Plus feature; this model updates through the Blockstream app.
Is it safe without a secure element chip?
Jade has no dedicated secure element chip. It uses a Virtual Secure Element built on a blind oracle, which lets the whole device be open source and protects a locked device against key extraction. The PIN is always required.
Original Jade or Jade Core?
If you want QR signing and a built-in battery, choose the original Jade. If you want a larger screen and Genuine Check and do not need a camera, choose Jade Core.
Will SIAMBC or Blockstream ever ask for my Seed Phrase?
Neither of us ever will, for any reason. Anyone who asks for your Seed Phrase or PIN, whether they claim to be SIAMBC staff, use the Blockstream name, or say it is for a warranty claim, identity check or firmware update, is a scammer.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.

Before you buy
Are your products genuine?
Yes. Every device we sell is new, sealed, genuine stock from authorized channels. SIAMBC has been Thailand's hardware wallet specialist since 2016 and has a physical store in Bangkok you can walk into.
This matters more than it sounds. A hardware wallet bought from an unknown marketplace seller can arrive already set up by someone else, with a recovery phrase they know. It is the one purchase where the seller genuinely matters.
How long does delivery take?
Orders normally arrive within 1 to 2 business days, depending on where you are — faster if you are in Bangkok.
Need it today? We can send it by Grab or LINEMAN for same-day delivery. Call us or message us on LINE to arrange it, pay by bank transfer, and it goes out immediately.
You are also welcome to collect from our Bangkok store.
Can I collect from your store instead?
Yes. We are in Thawi Watthana, Bangkok, open Monday to Saturday, 9:00 AM to 5:00 PM. You are welcome to come in, see the devices in person and ask questions before you buy. We answer in Thai and English. Find us here.
What warranty do I get?
Hardware wallets carry a 1-year warranty, claimed directly through us, with no waiting in an overseas support queue.
If a device is faulty out of the box, we replace it with a new one straight away. No forms, no waiting on the manufacturer.
The exception is the CryptoSafe range of steel recovery phrase backups: these products carry no warranty and cannot be returned or exchanged, as stated on their product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Can I set it up myself?
Yes, and you should do every step yourself. It takes a few minutes: you press every button on the device, create the wallet and write down your recovery phrase on your own.
Our step-by-step guides walk you through each step. If you get stuck, our team can answer on LINE or by phone, without ever seeing or asking for your recovery phrase.
Which model should I choose?
It depends on the phone you use and what you are protecting. The most common mistake is buying a wallet that does not work with your phone — the Ledger Nano S Plus does not support iPhone at all, and most Trezor models are view-only on iOS.
Compare every model side by side, or ask us. We will tell you honestly which one fits.
What happens if I lose my hardware wallet?
Nothing, as long as you still have your recovery phrase. The device only holds the keys — buy any compatible wallet, enter your phrase, and your crypto is back.
The real risk is losing the phrase itself. That is why we suggest keeping it on steel rather than the paper card in the box. Paper burns, water ruins it, and in Thailand termites eat it.
Will anyone ever ask for my recovery phrase?
No. Anyone who asks for it is a scammer, without exception. Neither SIAMBC nor any manufacturer will ever ask for your recovery phrase — not for a warranty claim, not for identity verification, not for a firmware update. Whoever has those words owns your crypto, and it can never be recovered.
