# FAQ

> Here are answers to the questions we get asked most often.

<AccordionGroup>
  <Accordion title="Which networks do you support?">
    Bitski wallet natively supports:

    * Ethereum mainnet
    * Ethereum Goerli
    * Polygon mainnet
    * Polygon Mumbai
    * Optimism mainnet
    * Arbitrum One mainnet

    If you'd like to use low-level RPC calls, we support any EVM chain. See our [Web3](/wallet-as-a-service/web-3/web3-get-started) docs for more information.

  <Accordion title="What are the benefits of Bitski managing key storage for new users?">
    Secure key storage is very challenging. One other possible option besides Bitski is a siloed approach. However, this approach, will be inconvenient for your users. Users will have to fund this wallet separately, and can then only manage their assets through your interface.
  </Accordion>

  <Accordion title="How should I integrate Bitski into my app?">
    A great place to start is via our connectors! We support many wallet list ecosystems like RainbowKit, BlockNative Onboard, and Web3Modal. [Check out our RainbowKit connector for an example](/integrations/connectors/rainbowkit).
  </Accordion>

  <Accordion title="I already have an app that uses Metamask, can I still use Bitski?">
    We designed the Bitski SDK to be compatible with other wallets and dapp browsers, while still providing a great experience for users who don't already have a wallet. Learn more about integrating our JS SDK [here](https://github.com/BitskiCo/bitski-js).
  </Accordion>

  <Accordion title="How are you storing and managing private keys?">
    Our keys are both created and stored on our HSMs (Hardware Security Modules). Approved transactions are passed to the HSM to sign. The keys never leave the hardware.
  </Accordion>

  <Accordion title="Do you have an Android SDK?">
    Not at the moment, but that is definitely on our roadmap!
  </Accordion>

  <Accordion title="How will users fund their wallet?">
    Currently for ETH, users can sign into our [web wallet](https://wallet.bitski.com/) and click **Get ETH** to purchase via credit card.
    However, if you're working with digital assets, we suggest using a backend with App Wallet to send assets to users directly. This prevents the need for the user to purchase ETH, while allowing them to have decentralized ownership.
