We have released Nayuta Wallet for Bitcoin and Lightning Network on October 18th, 2019.
Nayuta Wallet is a non-custodial wallet, meaning the user can fully control their funds. Private keys never leave their device and Nayuta nor third party cannot freeze or take away their funds.
Instead, they are only responsible for safeguarding their password and their 24-word passphrase that comes out in the "create a new wallet" in the app. Please make sure to keep the phrase secure, as losing or getting the phrase stolen means losing funds.
Also, Nayuta Wallet is still in open beta so we urge users to only use small amounts that they would be willing to lose as loss of funds is still possible.
