US Patent 11922363 Counterparty physical proximity verification for digital asset transfers

Embodiments are provided for verifying physical proximity of counterparties in digital asset transfers. A sender device receives a recipient hash and a recipient address are received, where recipient hash is generated by the recipient device based on each of the associated recipient address and a first set of location parameters. The sender device obtains a second set of location parameters that corresponds to a detected physical location thereof. The sender device employs the obtained second set of location parameters to decipher the recipient hash, and generates a request to transfer a digital token from a sender address associated with the sender device to the recipient address based on a determination that the deciphered recipient hash corresponds to the received recipient address.
