The Opendime is a unique Bitcoin bearer instrument that allows Bitcoin to be transferred physically, much like cash. Rather than functioning as a traditional hardware wallet, Opendime acts as a secure Bitcoin stick that can be loaded with Bitcoin and handed from person to person without requiring an on chain transaction each time ownership changes.
Private keys are generated securely inside the device and remain unknown to everyone, including the original owner and manufacturer. Recipients can verify that the device remains sealed and that the Bitcoin has not been compromised. When the owner decides to spend the Bitcoin, the device is physically unsealed, permanently revealing the private key.
Compact, portable, and completely self contained, Opendime offers a novel way to gift, store, or transfer Bitcoin while maintaining the simplicity of a physical bearer asset.
