[Lightspark Launches dotMoney Prototype, Test Funds Can Be Sent via Shared Links or .money Files] Odaily Planet Daily reports that Bitcoin News posted on the X platform stating Lightspark has released the dotMoney prototype. Users can send test funds via shared links, .money files, or directly between nearby iPhones. Files can be sent through AirDrop, instant messaging apps, or stored on USB drives; underlying funds are transferred between wallets via Spark. Each file can only be redeemed once—copying or forwarding will not generate duplicate funds—and the sender can cancel unclaimed payments. Currently, the prototype uses test funds with no monetary value. Lightspark is also testing bank withdrawals, Cash App, and Lightning withdrawal features through Grid.
