AI translates the explanation and quiz text while preserving code and answer scoring.

Over-the-air (OTA) update services like Expo Updates let you push new JS bundles directly to installed apps, skipping the app store review cycle — useful for urgent bug fixes but restricted by store policy (native code changes still need a full release).

import * as Updates from "expo-updates";

async function checkForUpdate() {
  const result = await Updates.checkForUpdateAsync();
  if (result.isAvailable) {
    await Updates.fetchUpdateAsync();
    await Updates.reloadAsync();
  }
}

For a wallet app, OTA updates are especially useful for fixing a broken RPC endpoint or a UI bug quickly, but any change touching signing logic or native modules deserves extra caution and a staged rollout given the financial stakes.
