Bitcoin News said in a post on X that @callebtc demonstrated a way to send Bitcoin-backed Cashu electronic cash through Apple’s Find My network. The setup uses a small device to disguise encrypted data as a Find My Bluetooth signal. Nearby Apple devices pick up that signal and relay it through Apple’s network, allowing the recipient to obtain the Cashu e-cash information. Under this design, the sending device does not need a Wi‑Fi or cellular connection. The post described the method as a transmission path that relies on Apple’s existing device network rather than a direct internet connection from the sender.
