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 Core is a Bitcoin and Liquid hardware wallet from Blockstream, one of the longest-standing engineering teams working on Bitcoin. It is open source in both firmware and hardware, which few other brands can say, and it is the most affordable way into the Jade family.
How Core differs from Jade Plus
The screen is the same as Jade Plus: a 1.9 inch IPS LCD at 320 x 170. What comes out is the camera and the battery. The rest is the same Jade.
- No camera, so it cannot sign by QR code with the network cut off. It connects over USB-C or Bluetooth instead
- No battery. It draws power over the cable while in use, so there is nothing to charge and no battery to degrade with age
- Plastic body, 65 x 30 x 12 mm, 20 g
How Jade holds your keys
Every Jade including Core uses what Blockstream call a Virtual Secure Element, built on blind oracle technology rather than a sealed secure chip inside the device. Every part of the device can therefore be inspected, with no component you have to trust without seeing the code.
Before you use it, the device has you set a PIN, and it supports a passphrase for anyone who wants another layer.
Bitcoin and Liquid only, on purpose
Jade Core supports Bitcoin and Liquid assets and no other chains. If you only hold Bitcoin, that limit works in your favor: less code means fewer places to go wrong, and the firmware is written by a team who work on Bitcoin infrastructure full time.
What it works with
The Blockstream app on Android, iOS and computer, along with Sparrow Wallet, Electrum and HWI.

- Everything in the box list is thereCheck against "What's in the box" above. If anything is missing or something unexpected is inside, do not use the device and contact us right away.
- No pry marks on the deviceCheck the body, edges, seams, the USB-C port and the screws. There should be no pry marks, scratches, glue residue or loose parts. If you find any, do not use the device and contact us right away.
- Every Seed Phrase sheet is blankIf any words are already written or printed on one, do not use the device.
- A new device has not been set upOn first power-on it should show Set Up Jade. If it asks for a PIN straight away, already holds a wallet, or someone gave you a PIN or Seed Phrase with it, do not use it.
- Run Genuine Check in the Blockstream appDuring setup the app asks you to tap Genuine Check, then select Yes on the Jade. If the app says the device is not genuine, do not use it and contact us right away. A device already set up can be checked again with Blockstream's web app.
- Download the app only from official sourcesUse the Blockstream app only from blockstream.com, the App Store or Google Play.
- No need to open the deviceChecking authenticity never requires opening the device. Opening it can damage it and voids the warranty.
Blockstream Jade Core FAQ
How much is the Blockstream Jade Core?
4,290 ฿ at SIAMBC.
What does it support?
Bitcoin only, including assets on Liquid, a Bitcoin layer 2. It does not support Ethereum or any other network.
With no battery, how do I use it?
Plug the USB-C cable into a computer, an Android phone, a charger or a power bank and it switches on as soon as it has power. There is nothing to charge and no battery to wear out in storage.
Does it work with an iPhone?
Yes. The Blockstream app on iPhone connects over Bluetooth only, and while you use it the device must be plugged into a charger or power bank, because it has no battery.
Can it sign by QR?
No. Jade Core has no camera, so it cannot do air-gapped QR signing or use SeedQR. For that, choose Jade Plus.
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.
How is it different from Jade Plus?
They share the same key protection and screen. Jade Core drops the camera and battery and has a plastic body; Jade Plus has a camera, a 280 mAh battery and takes a USB drive or SD card.
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.

Will anyone ask for my recovery phrase? Never. Anyone who does is a scammer.

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.
