Bitcoin Security, Made Easy The Blockstream Jade hardware wallet is designed to be user-friendly, making it easy for anyone to keep their Bitcoin safe. With just two buttons and a simple slide wheel, using Jade is straightforward, even if you're new to Bitcoin.

Follow the instructions with the included pamphlet, you will have your first Bitcoin wallet setup in five minutes! Advanced Security Features for Peace of Mind For the more advanced Bitcoiners, the Blockstream Jade hardware wallet takes security to the next level with a suite of advanced features designed to protect your Bitcoin. Air-Gapped Transactions: Sending air-gapped Bitcoin transactions with Blockstream Jade enhances security by ensuring that private keys never come into contact with online devices. This process involves generating and signing transactions on the offline Jade device, then transferring the signed transaction to an online device via QR codes. This method significantly reduces the risk of remote attacks, as the private keys remain completely isolated from potentially compromised internet-connected environments. Multisig Capabilities: Multisig, or multi-signature, is a security feature that requires multiple private keys to authorize a Bitcoin transaction. This setup protects against single points of failure, ensuring that even if one key is compromised, unauthorized transactions cannot occur without the other keys. Multisig is especially effective in safeguarding against theft, hacking, and accidental loss of funds by distributing the control and approval process across multiple, independent keys. Stateless Signing Device: Load a wallet to Jade temporarily by manually entering a recovery phrase or by scanning a supported QR format (such as SeedQR). This wallet will be forgotten on reboot and no information is saved to Jade. Passphrases: Adding a BIP39 passphrase to your Blockstream Jade provides an extra layer of security by allowing you to create a hidden wallet within your device. This passphrase acts as an additional password, required alongside your recovery phrase, making it more difficult for unauthorized users to access your funds. Anti-Exfil Protection A standout feature of Blockstream Jade is its Anti-Exfil technology, a pioneering security measure designed to thwart sophisticated key exfiltration attacks. This technology works by preventing malicious actors from extracting your private keys during a compromised transaction signing process. Instead of blindly signing transactions, Anti-Exfil requires external approval for each transaction, ensuring that even if an attacker gains access to your device, they cannot steal your Bitcoin. This innovative layer of protection makes your transactions significantly more secure and resistant to advanced hacking attempts. Multisig Shield for Enhanced Protection For those looking to take their security to the next level, Jade supports the creation of a Multisig Shield wallet. Multisig Shield offers robust protection against various attacks that can compromise software wallets. By adding two-factor authentication (2FA) with Multisig Shield, you can further secure your assets, making Blockstream Green the perfect companion for your Jade hardware wallet. Server-Enforced PIN Protection Blockstream Jade goes above and beyond to safeguard your recovery phrase. During setup, you'll choose a unique PIN, which, in combination with a blind PIN server, encrypts your Jade’s key material. This server-enforced PIN protection ensures that even if your device is stolen, physical attacks won't extract or steal your coins. Jade’s seed encryption uses random keys, split between the device and a lock-out server, providing an additional layer of security. Robust Key Generation for Ultimate Security Blockstream Jade generates its recovery phrase by combining internal entropy from its hardware with user-generated randomness, creating a highly secure and unpredictable set of private keys. The internal entropy provides a strong foundation of randomness, making it nearly impossible for attackers to replicate or predict the recovery phrase. For users seeking an additional layer of security, Jade allows you to enhance this process by rolling dice to introduce extra randomness. This method further increases the unpredictability of the recovery phrase, ensuring maximum protection for your Bitcoin. Open-Source, Transparent, and Trustworthy Blockstream Jade stands out in the Bitcoin community as a Free Open Source Software (FOSS) product, embodying the principles of transparency and trust that are paramount in the world of cryptocurrency. By being fully open-source, Jade allows anyone to scrutinize its code, ensuring there are no hidden vulnerabilities or backdoors. This commitment to openness not only fosters community trust but also empowers users by placing their security in their own hands. Choosing an open-source wallet like Jade means choosing a solution where security and user empowerment are prioritized above all else. Future-Proof Your Bitcoin Storage Blockstream Jade is designed with the future in mind, receiving regular firmware updates to keep your wallet secure against the latest threats. By choosing Jade, you're investing in a hardware wallet that will protect your Bitcoin for years to come.
