Progress on Electrum-NMC
Jun 17, 2017 • ahmedbodi
Work on the electrum port for Namecoin has been moving along nicely. It was decided that we will use the electrum-client from spesmilo, along with the electrumX server. ElectrumX was chosen due to the original electrum-server being discontinued a few months ago. So far the electrum client has been ported over for compatability with electrumX. This includes the re-branding, blockchain parameters and other electrum related settings for blockchain verification
On the roadmap now are:
Extend electrumX NMC Support to allow for full veritification of AuxPow
Modify new electrum client to verify the new AuxPow
Add Name handling support to electrum
These repo’s are for testing purposes only. Do not use these unless your willing to risk losing funds.

Thank you for information.It is very strange oldest alt coin [namecoin] the only coin other than bitcoin known to be associated with satoshi has no working electrum client.
