37. Building and releasing (EAS/App Store/Play Store)

Getting a build onto real devices and stores.

Expo Application Services (EAS) builds native binaries in the cloud without requiring a local Xcode/Android Studio setup, producing an `.ipa`/`.aab` ready for store submission.

// eas.json
{
  "build": {
    "production": { "distribution": "store" }
  }
}
eas build --platform ios --profile production
eas submit --platform ios

Version bumps, code signing, and store metadata (screenshots, privacy policy — important for wallet apps that request sensitive permissions) all need to be in order before submission, and each store's review can reject apps that reference crypto trading without proper disclosures.

  2. 2. What file configures EAS build profiles?

  3. 3. Why might app stores scrutinize wallet/crypto apps more?
