• The variable 'waddr' is used to construct the wireAddrs map but is not defined in the revised SetupAppClient. Please declare and initialize waddr (e.g., by converting eaddress using the appropriate function) before using it in the map.

wireAddrs := map[wallet.BackendID]wire.Address{ethwallet.BackendID: waddr}
