How does Jade work with Lightning if it's a hardware wallet? The @Liquid Network is the bridge. When someone sends a Lightning payment to your Blockstream app wallet, it arrives as LBTC in your Jade-secured wallet. When you pay a Lightning invoice, your LBTC swaps out over Lightning. Addresses are generated offline. Jade signs every transaction. Private keys never touch an internet-connected device. See exactly how much you could keep in your DCA stack by utilizing Lightning to Liquid swaps. Check out Blockstream's new UTXO fee calculator. 🔗
