Even if your device is physically compromised, your bitcoin remains secure. • Genuine Check: When pairing your Jade Plus with Green, Green verifies that the Jade was produced by Blockstream, helping thwart evil-maid attacks. • Secure Boot and Anti-Exfil: Secure Boot makes sure only signed Blockstream software runs on your Jade, keeping your encrypted recovery phrase safe. Anti-Exfil adds another layer of security by forcing the device to include random data in signatures, preventing attackers from slowly extracting your private keys. • Air-Gapped Security Workflows: With SD card support, a built-in battery, and a color camera, Jade Plus enables fully air-gapped operations. Sign transactions, scan QR codes, and update firmware completely offline, ensuring your private keys remain isolated from online threats. 🔗 Seamless Connectivity for Every Workflow • USB and Bluetooth Support: Connect Jade Plus to desktop or mobile with ease, ensuring a seamless experience for every transaction. • Camera Unlock: Unlock your Jade using SeedQR or QR PIN Unlock through the built-in color camera. • Compatible with Leading Wallets: Jade Plus integrates with popular Bitcoin wallets such as Blockstream Green, Sparrow, Specter, and Bitcoin Core, making it easy to use across a variety of platforms. • Blockstream Green Integration: Easily pair Jade Plus with Blockstream Green to purchase bitcoin and store it directly on your device, streamlining the entire process. 10% off on Blockstream store products with coupon "maximus". rewards.blockstream.com/maxi…

Giving an app access to Core Lightning need not mean handing it unrestricted control. A rune can carry restrictions on methods, time or peer identity. More restrictions can be appended before sharing it; removing existing restrictions makes it invalid. There is a subtle resource boundary: derived runes retain the same ID and compete for the parent's rate limit. Plan delegation with that shared budget in mind. Keep the broader original private; restricting a copy does not narrow the original's powers. docs.corelightning.org/refer…

In a Simplicity contract, subtraction needs a question beyond “what is the result?” The official allowance example uses subtract_64, which returns a borrow flag alongside the difference. The contract explicitly asserts that the flag is false before relying on that difference. Simplicity has no exceptions to catch here. Correct arithmetic handling belongs in the contract's conditions. A returned number alone is not evidence that the economic calculation stayed within its intended range. docs.simplicity-lang.org/

Holding an issued asset on Liquid does not mean you have what is needed to pay its transaction fee. Liquid currently accepts L-BTC for fees, including transactions sending another asset. Fees are represented by explicit, unblinded fee outputs. That creates a practical wallet requirement: account for fee funding as well as the asset being transferred. If a service sponsors fees, that changes who supplies the L-BTC; it does not turn the issued asset into the network's fee currency. docs.liquid.net/docs/liquid-…

A Jade can be powered on without its wallet being ready for your connection. The get_version_info RPC reports wallet state and JADE_INTERFACE. The documentation says that while one interface holds the unlocked wallet, another cannot use it. Listed interface values include QR, SERIAL and BLE. For integration debugging, inspect that state before treating a second connection as a signing failure. A READY response describes interface availability; it does not approve the transaction you intend to sign. raw.githubusercontent.com/Bl… Code: maximus Affiliate link rewards.blockstream.com/maxi…

A mainnet-initialized Jade can still be used for a temporary testnet session. The documented Temporary Signer flow bypasses the PIN-saved wallet and asks for the network each time. The saved wallet's network choice remains tied to its initialization; changing that saved setup to testnet requires a factory reset. For practice, use a separate test recovery phrase. Do not reset a funded setup just to experiment, and check the companion app's testnet setting before assuming the option is missing. help.blockstream.com/blockst… Code: maximus Affiliate link rewards.blockstream.com/maxi…

The words are the last step of Jade's recovery-phrase generation. Blockstream documents an entropy accumulator with a 32-byte state. SHA512 mixes the previous state with entropy inputs; one half of the result becomes the new state, while the other supplies entropy to the BIP39 phrase-generation function. The mechanism matters more than counting sensors. This describes the documented design, not an independent measurement of entropy quality or a promise that a device can never fail. help.blockstream.com/blockst… Code: maximus Affiliate link rewards.blockstream.com/maxi…
