OmniWallet which is an allegedly safe web based wallet

or Omni core desktop wallet, but for that you will need to download the bitcoin blockchain to your desktop, which will take a few days and use up a lot of disk space.

Both can be found on the omni layer web page.  http://www.omnilayer.org/


I have some amps in omniwallet. It's fairly straightforward.  I've downloaded omni core but not tried it yet with an actual transaction so cannot comment on it.
