o1 Mobile can open a Coinbase-hosted fiat onramp for eligible users and regions. This is an optional funding method, not an o1-operated exchange or payment flow.

​
How it works

1

Choose Deposit

Open a deposit flow from the cash balance or another available entry point.
2

Select the Coinbase option

o1 Mobile requests a hosted onramp URL configured to deliver USDC to the user’s Base wallet.
3

Continue in the browser authentication session

Complete the Coinbase-hosted flow in an operating-system browser authentication session, not an embedded trading WebView.
4

Return to the app

After the purchase or transfer completes, the wallet balance updates when the network transaction and account data are available.

​
Third-party service

Coinbase determines:
  • supported countries and regions;
  • identity-verification requirements;
  • accepted payment methods;
  • purchase limits;
  • payment and service fees; and
  • transaction approval or rejection.
o1 does not collect payment-card details in the native mobile interface.
Payment methods such as cards, bank transfers, Apple Pay, or other wallets depend on the options Coinbase presents for the user’s location and account.

​
Alternative: crypto deposit

Users can also fund the in-app cash balance by sending USDC on Base from another wallet or exchange. Verify the asset, network, and destination address before sending.
