Overview

Enable users to easily fund their crypto wallet. These demo apps will get you up and running with a basic Onramp API integration for mobile or web.

Mobile demo app (v2)

A React Native + Expo mobile app demonstrating Coinbase’s Onramp v2 API with CDP Wallets, Apple Pay integration, and real-time push notifications. The app uses Smart Accounts (ERC-4337) for all EVM transactions and supports gasless transfers for USDC, EURC, and cbBTC on Base. API keys are never exposed to the client (a secure backend proxy handles all CDP API calls).
