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

​
Create your account

1

Open o1 Mobile

Install o1 Mobile from the official store listing and open the app.
2

Choose a sign-in method

Continue with email, Google, or Apple. The app creates or restores the wallet associated with your account.
3

Secure your account

Enable the available device-security controls and review Wallet and Security before depositing assets.

​
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

1

Find a token

Use Market or Search to select a token on a supported network.
2

Choose Buy or Sell

Enter the amount and review the quoted route, expected output, fee, and other available transaction details.

Confirm the swap

Complete the confirmation control to authorize the app to submit the onchain transaction from your wallet.
4

Review the result

Wait for the transaction status, then review the updated balance and transaction history.
Blockchain transactions are irreversible after confirmation. Quotes can change because of price movement, liquidity, network conditions, or routing availability.
