    A must have!

    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.

    the Claimable NEO Gas is not consistent with NEON Wallet. If I claim it in O3 wallet, im not receiving what is presented as claimable. If I claim it in NEON wallet and it appears correctly in O3 wallet.

    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! ^^

    My coins stuck - Neo Compatible address support doesn't work

    I staked my ONT via O3 app. It used to support NEO Compatible ONT addresses. Now it doesn't, and my coins are stuck & I can't remove them!!! I have been in contact with support, and after weeks, still no solution; Their only response was "Use OWallet instead" but that doesn't work with NEO compatible addresses!
