Best NEO & Ontology wallet

This wallet seriously has everything. Can manage my NEO and Ontology funds from my ledger all in one place, and can quickly switch between my different accounts! There’s no going back now! ^^

I have multiple wallets and this app makes it so easy to manage all of them. It also supports Ledger. If you hold any NEO assets or Ontology assets. give it a try. such a great app.
