If you prefer customized development and don’t want to use Cobo’s ready-made pages, you can integrate Web3 payment capabilities into your own frontend by using React SDK provided by Cobo.

React SDK provides core Web3 capabilities such as token selector with exchange rate, QR code with amount, and connecting third-party wallet to submit transaction. You can focus on Web2 business logic without implementing Web3 payment details yourself. For integration steps and component demos, see the React SDK interactive documentation.

SDK Authentication

React SDK must be authenticated before use. Authentication requires your frontend and backend to work together, as follows:
  1. The backend calls Create SDK link to create an SDK-only token.
  2. The backend returns the token to the frontend.
  3. The frontend passes the token to the SDK using the setAccessToken method.
