Abstract: An escrow non-face-to-face cryptocurrency transaction device and method using a phone number is proposed. The device and method includes: providing a phone number wallet that uses a phone number of a user as a login ID; using the phone number wallet having an electronic wallet address of a phone number system so as to remit and deposit cryptocurrency stored in the phone number wallet in an escrow virtual wallet of an escrow virtual wallet address generated for a one-time use in a one-time escrow virtual wallet; transmitting, to a remitter, escrow authentication information that enables a secure connection to the escrow virtual wallet and enables withdrawal authentication; and remitting the cryptocurrency deposited in the escrow virtual wallet address to an electronic wallet address of a recipient who inputs the escrow authentication information directly received from the remitter, so as to withdraw the cryptocurrency.
