Developer enables BTC-linked token transfers via Apple's 'Find My'

A developer of the open-source electronic cash protocol Cashu has implemented a method to send tokens redeemable for Bitcoin from offline devices using Apple’s 'Find My' network. This method involves a small device sending the token over Bluetooth, similar to a lost AirTag alert. Nearby iPhones relay the signal through the 'Find My' network, allowing the recipient to reconstruct the token. The developer cautioned that the transmitted data is public, meaning anyone who obtains the token can use it, and advised sending only small amounts that can be safely lost. The transfer process is slow and relies on Apple’s unofficial interface, which may cease to function if Apple makes changes.
