Coinbase® Extension® - Set up the

The Coinbase Wallet extension lets you access web3 and connect to thousands of dapps across Ethereum and all EVM-compatible networks, including …

Creating a Coinbase extension typically involves integrating with the Coinbase API and implementing the necessary functionality. Here's a high-level step-by-step guide to help you get started:

  1. Create a Coinbase Developer Account:

    • Go to the Coinbase Developer portal (https://developers.coinbase.com/).

    • Sign in or create a new account.

    • Create a new OAuth 2.0 application to obtain API credentials.

  2. Get API Credentials:

    • After creating the application, you'll receive API key and secret credentials.

    • Keep these credentials secure, as they will be used to authenticate your extension with Coinbase.

  3. Understand Coinbase API:

    • Familiarize yourself with the Coinbase API documentation (https://developers.coinbase.com/docs/wallet/overview).

    • Understand the endpoints and functionalities relevant to your extension (e.g., retrieving account information, checking balances, creating transactions).

  4. Choose a Development Platform:

    • Decide where your extension will be hosted. It could be a web application, a browser extension, or a mobile app.

    • Set up a development environment, including the necessary tools and libraries.

  5. Integrate OAuth 2.0 Authentication:

    • Implement OAuth 2.0 authentication to allow users to authorize your extension to access their Coinbase account.

    • Use the Coinbase OAuth endpoints to initiate the authentication flow.

  6. Implement Extension Frontend:

    • Create the user interface for your extension. This may include views for connecting Coinbase accounts, viewing balances, and initiating transactions.

    • Use a framework or library that fits your development platform.

  7. Handle Coinbase API Requests:

    • Write the code to make API requests to Coinbase using the credentials obtained earlier.

    • Implement logic to handle responses and update the UI accordingly.

  8. Implement Transaction Features:

    • If your extension involves transactions (buying, selling, transferring), implement the necessary features.

    • Handle user input for transaction details and send appropriate requests to Coinbase.

  9. Test Extensively:

    • Test your extension thoroughly in different environments.

    • Check for edge cases and handle errors gracefully.

  10. Comply with Security Best Practices:

    • Ensure that sensitive information, such as API credentials, is handled securely.

    • Implement HTTPS for communication between your extension and any backend services.

  11. Review Coinbase API Rate Limits:

    • Be aware of Coinbase API rate limits and implement necessary throttling and error handling.

  12. Deploy Your Extension:

    • Once testing is successful, deploy your extension to the intended platform.

    • If it's a web application, deploy it to a hosting service.

  13. Monitor and Maintain:

    • Monitor your extension for any issues or changes in the Coinbase API.

    • Keep your extension updated to address any security vulnerabilities or improvements.

Remember to refer to the official Coinbase API documentation for detailed information on endpoints, authentication, and best practices.
