摘要： A method for preventing a hardware wallet from being maliciously paired, comprising: a hardware wallet waiting to receive a connection request; when a connection request is received, determining whether a first terminal sending the connection request has been paired and connected; if so, waiting to receive an instruction of the first terminal; and when receiving a pairing transfer instruction sent by the first terminal, clearing terminal information stored in a whitelist of the hardware wallet. By means of the present technical solution, a hardware wallet can achieve pairing transfer only by means of the authorization of a previously paired terminal, thereby improving the security of the hardware wallet.
