Publication number: 20240013212Abstract: Provided herein are systems, devices and methods for transferring cryptocurrency from a limited access cryptocurrency wallet. The limited access cryptocurrency wallet may create, in advance, provisional account(s) allocated for respective recipient(s) and transfer a predefined overall value of cryptocurrency from its associated account associated to the provisional account(s). The limited access cryptocurrency wallet may further generate, in advance, a plurality of signed transactions for transferring a plurality of predefined partial values of cryptocurrency from the provisional account(s) to receiving account(s) associated with the recipient(s) and transmit the plurality of signed transactions to a network connected device. Later, in real-time, the network connected device may transmit one or more of the plurality of signed transactions for transferring cryptocurrency from the provisional account(s) to the receiving account(s) without physically attending to the limited access cryptocurrency wallet.Type: ApplicationFiled: August 11, 2021Publication date: January 11, 2024Applicant: GK8 LTDInventors: Shahar SHAMAI, Lior LAMESH
