xBull Wallet is a non-custodial app developed by Creit Technologies LLP that lets you manage all you Stellar key pairs in a professional way and interact with websites/apps on the Soroban/Stellar networks.
You wont need to share your private keys with websites/apps because youll be able to interact with them and sign transactions requested directly from within the app.
Create new Mnemonic phrases, import old ones, import individual secret keys, connect hardware devices like KeyStone, use your own Horizon APIs (by default xBull uses the free to use Stellar Foundation Horizon APIs).
