Blockstream Jade Core

Blockstream Jade Core is an open-source Bitcoin hardware wallet built for first-time self-custody. Jade Core offers a vibrant color display and buttons for clear navigation, as well as USB-C and Bluetooth connectivity for easy pairing with the Blockstream app on mobile and desktop.

  • Bech32
    Bech32 is a special address format made possible by SegWit (see the feature description for SegWit for more info). This address format is also known as 'bc1 addresses'. Some Bitcoin wallets and services do not yet support sending or receiving to Bech32 addresses.
  • Hardware Wallet
    Some wallets can pair and connect to a hardware wallet in addition to being able to send to them. While sending to a hardware wallet is something most all wallets can do, being able to pair with one is a unique feature. This feature enables you to be able to send and receive directly to and from a hardware wallet.
  • Legacy Addresses
    Most wallets have the ability to send and receive with legacy bitcoin addresses. Legacy addresses start with 1 or 3 (as opposed to starting with bc1). Without legacy address support, you may not be able to receive bitcoin from older wallets or exchanges.
  • Multisig
    Some wallets have the ability to require more than one key to authorize a transaction. This can be used to divide responsibility and control over multiple parties.
  • SegWit
    Some wallets support SegWit, which uses blockchain space more efficiently. This helps reduce fees paid by helping the Bitcoin network scale and sets the foundation for second layer solutions such as the Lightning Network.
  • Taproot
    Some wallets support Taproot, which can increase privacy and use blockchain space more efficiently for complex transactions such as multisig. Some Bitcoin wallets and services do not yet support sending or receiving to the Bech32m addresses (which begin with 'bc1p') which Taproot uses.
