Abstract: Digital currency transfer security systems including a digital network, a first device configured to store and transfer digital currency, and a second device configured to provide a security measure during transfer of digital currency from the first device are described. The first device is configured to provide a first public key and provide a first private key signature, the first public key being accessible via the first private key signature. The second device is configured to provide a second public key and provide a second private key signature, the second public key being accessible via the second private key signature. Providing the first public key from the first device and the second public key from the second device generates a multisignature public key capable of storing and transferring digital currency, the multisignature public key being accessible for transfer of digital currency via the first private key signature and the second private key signature.
