Cake Wallet Launches Cupcake App to Transform Spare Devices into Cold Storage

Cake Wallet's new Cupcake app turns idle smartphones and tablets into secure, air-gapped cold storage for cryptocurrencies. Launched on September 11, 2025, the free, open-source solution eliminates the need for hardware wallets while maintaining robust security.

The app keeps private keys offline, connecting in view-only mode with Cake Wallet for transaction initiation. Signing occurs offline on Cupcake, creating a hardware wallet-like security LAYER without supply chain risks or additional costs.

As digital asset values rise, so does demand for theft-resistant storage. Traditional hardware wallets face challenges including price barriers and logistical constraints. Cupcake's innovative approach leverages existing devices, potentially democratizing secure crypto storage.
