Kindly note that XDNA is no longer supported by the Flits app. This is effective immediately and for the foreseeable future. Our technical team have continually tried to offer support for the coin, though forking remains a huge issue.
Though there is an explorer, it has not proven to be as reliable as the technical team would have liked (I.e. not always running, so not always possible to see where it is at).
Holders of XDNA will therefore be unable to send/receive and/or run masternodes at this time. Affected users can (at their OWN RISK) make use of the Official Flits Extraction Tool – available from the Official Flits GitHub: https://github.com/flitsnode/flits-extraction-tool
