The device is now available locally through BitcoinVN Shop.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Jade Core keeps private keys isolated from internet-connected devices and signs transactions offline.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Compared with the <\/span><a href=\"https:\/\/bitcoinvn.io\/shop\/product\/blockstream-jade-plus\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">more advanced Jade Plus<\/span><\/a><span style=\"font-weight: 400;\">, Jade Core leaves out premium features such as the camera, battery and support for air-gapped QR signing. This keeps both the device and the setup simpler while retaining the security most Bitcoin holders actually need.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Jade Core is therefore best suited to first-time hardware wallet users, regular Bitcoin savers and anyone who wants reliable long-term storage without paying extra for advanced features they are unlikely to use.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As always, buying through BitcoinVN Shop means receiving a genuine device locally in Vietnam &#8211; <\/span><a href=\"https:\/\/bitcoinvn.io\/insights\/risks-of-self-importing-cold-wallets-into-vietnam\/\"><span style=\"font-weight: 400;\">without international shipping delays or customs complications<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<h2><b>How is my seed phrase generated?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Following the recent<\/span><a href=\"https:\/\/bitcoinvn.io\/shop\/new-era-for-self-custody-after-coldcard\/\" target=\"_blank\" rel=\"noopener\"> <span style=\"font-weight: 400;\">Coldcard seed-generation failure<\/span><\/a><span style=\"font-weight: 400;\">, many hardware wallet users are understandably paying closer attention to how their seed phrase is created.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During setup, Jade Core creates a fresh 12- or 24-word seed phrase directly on the device using its onboard true random number generator. Only you receive the phrase, which should be written down and kept safely offline.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Users can also add an <\/span><a href=\"https:\/\/bitcoinvn.io\/insights\/passphrase-enhance-wallet-security\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">optional passphrase<\/span><\/a><span style=\"font-weight: 400;\"> for an additional layer of protection and access to a separate hidden wallet. The device does not store it, so it must be entered each time &#8211; and <\/span><b>losing it means permanently losing access to that wallet.\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A device-generated seed still requires some trust that the hardware and software work as intended. Jade Core reduces this \u201cblack box\u201d element by making both fully open source, allowing its design and code to be independently inspected &#8211; although open source alone can never guarantee that software contains no bugs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Advanced users who prefer not to rely solely on the device can instead<\/span><a href=\"https:\/\/help.blockstream.com\/blockstream-jade\/add-more-security-functionality\/create-a-recovery-phrase-using-dice\" target=\"_blank\" rel=\"noopener\"> <span style=\"font-weight: 400;\">generate a valid BIP39 seed phrase using private dice rolls<\/span><\/a><span style=\"font-weight: 400;\">, with Jade Core helping to calculate the final word. An existing 12- or 24-word BIP39 phrase can also be imported, although a phrase previously exposed to an ordinary computer should not be considered newly secured simply because it is transferred to a hardware wallet.<\/span><\/p>\n<h2><b>Life Savings vs. Daily Driver<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Following the Coldcard seed-generation failure, BitcoinVN emphasized an important distinction that we intend to make clearer in our custody communications going forward:\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Removing signing capabilities &#8211; meaning private keys and seed phrases &#8211; from internet-connected devices does, in our observation, <\/span><a href=\"https:\/\/bitcoinvn.io\/insights\/category\/cybersec-custody\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">prevent the vast majority of common cryptocurrency thefts<\/span><\/a><span style=\"font-weight: 400;\"> and is therefore a prudent step. However, a single-signature hardware wallet is not the place or setup in which to store significant parts of your life savings or net worth.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-9560 size-full\" src=\"https:\/\/bitcoinvn.io\/shop\/wp-content\/uploads\/2026\/08\/blockstream-jade-core-2.webp\" alt=\"\" width=\"800\" height=\"400\" srcset=\"https:\/\/bitcoinvn.io\/shop\/wp-content\/uploads\/2026\/08\/blockstream-jade-core-2.webp 800w, https:\/\/bitcoinvn.io\/shop\/wp-content\/uploads\/2026\/08\/blockstream-jade-core-2-300x150.webp 300w, https:\/\/bitcoinvn.io\/shop\/wp-content\/uploads\/2026\/08\/blockstream-jade-core-2-768x384.webp 768w, https:\/\/bitcoinvn.io\/shop\/wp-content\/uploads\/2026\/08\/blockstream-jade-core-2-600x300.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">While hardware-wallet seed-generation failures remain rare tail events, you never want such a failure to negatively affect your life for years, decades or even generations to come.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At a certain point, responsible risk management requires moving to a more redundant and secure setup, such as <\/span><a href=\"https:\/\/bitcoinvn.io\/insights\/multivendor-multisig\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">multivendor multisig<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h2><b>Multivendor Multisig<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The term \u201cmultivendor multisig\u201d often sounds daunting to those who are not yet familiar with the concept.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In truth, however, multivendor multisig provides a margin of error: <\/span><b>you can make mistakes and survive them.<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Whether you lose one of the keys, a threat actor gains access to it, or a hardware-wallet manufacturer supplies a device with faulty seed generation &#8211; as happened in the recent Coldcard case &#8211; a properly configured multivendor multisig setup remains secure because no single key is sufficient to authorize a transaction. The affected key can therefore be calmly replaced. By contrast, if your funds depend on only one key, seed phrase or vendor, any of these failures could result in catastrophic losses.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At a certain level of wealth, implementing multivendor multisig becomes a no-brainer &#8211; you do not want your financial future to depend on a single device or manufacturer.<\/span><\/p>\n<p><b>We are not aware of any publicly reported losses among Coldcard users<\/b><span style=\"font-weight: 400;\"> who used an affected device only as one signer in a properly configured multivendor multisig. Because a single compromised key was insufficient to reach the signing threshold, the affected device could be safely rotated out without placing the entire wallet at the mercy of that one signer.\u00a0<\/span><\/p>\n<h2><b>Need further custody guidance?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While all of this can be done on a DIY basis, we understand that some people prefer to go through the process with an experienced hand at their side &#8211; especially when the long-term secure self-custody of their coins is concerned. Experienced, professional guidance helps ensure that the setup is initiated correctly and that no avoidable weaknesses are introduced along the way.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this reason, some of our clients choose to<\/span><a href=\"http:\/\/bitcoinvn.io\/consulting\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\"> book time with one of our in-house cybersecurity consultants<\/span><\/a><span style=\"font-weight: 400;\">, who can guide them through the initial setup in a secure environment, address any uncertainties and help them avoid common pitfalls. The consultant never needs access to the client\u2019s seed phrases or private keys (<\/span><b>no legitimate consultant or support agent will ever ask a client to disclose them<\/b><span style=\"font-weight: 400;\">).<\/span><\/p>\n<h2><b>Buy hardware wallet anonymously?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">As the recent &#8211; and increasingly frequent &#8211; breaches of customer data across the hardware-wallet industry show, privacy at the point of purchase matters.
