Clone the repository and navigate to the project folder:\n\n```bash\ngit clone https://github.com/crossmint/fintech-solana-wallets-expo-quickstart.git \u0026\u0026 cd fintech-solana-wallets-expo-quickstart\n```\n\n2. Install all dependencies:\n\n```bash\nnpm install\n# or\nyarn install\n# or\npnpm install\n# or\nbun install\n```\n\n3. Set up the environment variables:\n\n```bash\ncp .env.template .env\n```\n4. Set up your Crossmint API key. This quickstart needs to use a production API key:\n   \n   a. Generate a Crossmint API key from [here](https://docs.crossmint.com/introduction/platform/api-keys/client-side).\n   \n   b. To authenticate requests from your app, whitelist the app domain by selecting \"Mobile\" under \"App type\" and entering your iOS bundle ID and Android package name from `app.json` (by default this quickstart uses \"com.crossmint.fintech.solana.wallets\").\n\n   c. Select all the scopes for wallets and users.\n\n5. Add the API key to the `.env` file.\n\n```bash\nEXPO_PUBLIC_CLIENT_CROSSMINT_API_KEY=your_api_key\n```\n\n6. Sign up for a [Helius](https://helius.dev/) account and get an API key.\n\n7. Add the API key to the `.env` file.\n\n```bash\nEXPO_PUBLIC_HELIUS_API_KEY=\"000000000-0000-0000-0000-000000000000\"\n```\n\n8. Sign up for a [Lulo](https://dev.lulo.fi/) account, create a project and get an API key.\n\n9. Add the API key to the `.env` file.\n\n```bash\nEXPO_PUBLIC_LULO_API_KEY=\"000000000-0000-0000-0000-000000000000\"\n```\n\n10. Run the app locally:\n\n```bash\nnpm run start\n# or\nyarn start\n# or\npnpm start\n# or\nbun start\n```\n\nNote: When running an iOS development build, make sure you're running the latest version on the simulator (\u003eiOS 18).\n\n## Necessary polyfills\n\nCheck out [polyfills.ts](lib/polyfills.ts) and [metro.config.js](metro.config.js) for the necessary polyfills to send Solana transactions. Make sure to keep these in your Expo app.\n\n## Errors when running in iOS simulator\n\nIf you encounter errors trying to run the expo app on iOS, try running:\n\n```bash\nnpx expo install --fix\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrossmint%2Ffintech-solana-wallets-expo-quickstart","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcrossmint%2Ffintech-solana-wallets-expo-quickstart","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcrossmint%2Ffintech-solana-wallets-expo-quickstart/lists"}
