# Set up o1 Mobile

> Set up o1 Mobile, fund your wallet, and complete a decentralized spot swap.

o1 Mobile combines account access, a user-specific wallet, market discovery,
and spot swaps in one mobile flow.

## Create your account

<Steps>
  <Step title="Open o1 Mobile">
    Install o1 Mobile from the official store listing and open the app.
  </Step>

  <Step title="Choose a sign-in method">
    Continue with email, Google, or Apple. The app creates or restores the
    wallet associated with your account.
  </Step>

  <Step title="Secure your account">
    Enable the available device-security controls and review
    [Wallet and Security](/mobile/wallet-and-security) before depositing
    assets.
  </Step>
</Steps>

## Fund your wallet

The in-app cash balance used for Buy routes is **USDC on Base**. You can fund
it in either of these ways:

* **Crypto deposit:** send USDC on Base to the displayed Base wallet address.
* **Fiat onramp:** use the Coinbase-hosted flow where it is available. The
  third-party purchase experience opens in an operating-system browser
  authentication session and is configured to deliver USDC to the Base wallet.

Other wallet assets can be received through their compatible network
addresses. Always verify the asset, destination network, and address before
sending funds. Assets sent on an unsupported network may not be recoverable.

## Complete a spot swap

<Steps>
  <Step title="Find a token">
    Use Market or Search to select a token on a supported network.
  </Step>

  <Step title="Choose Buy or Sell">
    Enter the amount and review the quoted route, expected output, fee, and
    other available transaction details.
  </Step>

  <Step title="Confirm the swap">
    Complete the confirmation control to authorize the app to submit the
    onchain transaction from your wallet.
  </Step>

  <Step title="Review the result">
    Wait for the transaction status, then review the updated balance and
    transaction history.
  </Step>
</Steps>

<Warning>
  Blockchain transactions are irreversible after confirmation. Quotes can
  change because of price movement, liquidity, network conditions, or routing
  availability.
</Warning>
