    ),
    peerMeta = WCPeerMeta(
        appId = "NWC1004HS6VFTPPPLUGFQBQ5SFNWB79B",        // Used as Dapp storage delimiter
        name = "Dapp Sample",                              // Dapp name to display on the screen
        url = "https://www.sample.com/",                   // Dapp introduction URL to display on the screen
        description = "Dapp Platform",                     // Brief introduction
        icons = listOf(""),                                // Dapp icon URL to display on the screen
