Disclosed is a method for use in a virtual asset transmission from a sender having a sending account at a sending virtual asset service provider (sending VASP) to a recipient having a receiving account at a receiving virtual asset service provider (receiving VASP). The method involves sending, to the receiving VASP, a first request for verifying the receiving account of the recipient at the receiving VASP; receiving, from the receiving VASP, a verification result confirming that the receiving account of the recipient at the receiving VASP is valid; subsequently receiving, from the sending VASP, a second request for verifying a blockchain record for a transmission of a virtual asset from the sender to the recipient; upon receipt of the second request, determining if the transmission has been recorded on a blockchain network; and upon determining that the transmission has been recorded on the blockchain network, sending, to the receiving VASP, a third request to update the receiving account of the recipient at the receiving VASP about the transmission of the virtual asset from the sender to the recipient.

Method for virtual asset transmission

A method for identifying a wallet address associated with a virtual asset service provider is provided. The method comprises receiving a target wallet address, obtaining a transaction of a virtual asset associated with the target wallet address, obtaining a list of a plurality of known wallet addresses of virtual asset service providers (VASPs) and identifying a type of the target wallet address, by performing at least one of a cold wallet determination routine and a hot wallet determination routine for the target wallet address, based on the transaction and the list of known wallet addresses of the VASPs.

Method and apparatus for identifying wallets associated with virtual asset service providers

A method for mediating virtual asset transmission is provided. The method comprises receiving a first information on virtual asset to be transmitted from a first user to a second user from a first virtual asset service provider (VASP) server managing virtual asset of the first user, transmitting a verification request as to whether information on the second user included in the received first information is correct to a second VASP server managing virtual asset of the second user, receiving a verification result indicating that the information on the second user is correct from the second VASP server as a response to the verification request, and transmitting the received verification result to the first VASP server. The method further comprises transmitting virtual asset update request of the second user to the second VASP server if it is determined that the transaction has been recorded in the blockchain.
