"This is a breakthrough for self-custody. Jade is the first hardware wallet in the world to send and receive Lightning payments while keeping your keys fully offline. Blockstream is uniquely positioned to deliver this. Our full-stack infrastructure connects all three Bitcoin layers to make this possible on a single hardware wallet."
"Lightning transactions have required either hot wallets connected to the internet or custodial services that hold funds on behalf of users. While those tools allow instant payments and low fees, they introduce security risks that many long-term holders prefer to avoid."
"When a user receives a Lightning payment through the Blockstream app, the software generates a Lightning invoice and automatically performs an atomic swap that converts the incoming payment into LBTC. The funds then settle into the user's Jade-secured account."
Blockstream has released version 5.2.0 of its Green app, enabling the Jade hardware wallet to send and receive Lightning Network payments while keeping funds in cold storage. The feature uses atomic swaps to convert Lightning payments into Liquid bitcoin (LBTC) secured by the Jade device. This addresses a fundamental limitation in the Lightning ecosystem, which previously required either internet-connected hot wallets or custodial services. By connecting Lightning payments to hardware wallet security through Blockstream's full-stack infrastructure spanning three Bitcoin layers, the update merges two previously disconnected components of the Bitcoin ecosystem, offering users instant payments with low fees while maintaining the security benefits of offline key storage.
