+Because Safari uses the popup fallback, open the wallet directly from the user's tap. Avoid `await`ing config fetches, dynamic imports, or other setup before calling `provider.request({ method: 'wallet_connect' })`; preload that work before rendering the button. See [`Dialog.popup`](/accounts/api/dialog.popup#mobile-safari-popup-blocking) for the recommended handler pattern.

+## Mobile Safari popup blocking
+
+Mobile Safari blocks popups unless they open directly from the user's tap. Preload the Accounts SDK, provider, and any app configuration before the user taps a connect or payment button. In the tap handler, call the wallet request immediately, then continue the rest of your flow after the wallet responds.
+
+```tsx
+function ConnectButton({ provider }: { provider: Provider }) {
+  return (
+    <button
+      onClick={async () => {
+        const result = await provider.request({ method: 'wallet_connect' })
+        await continueAfterConnect(result)
+      }}
+    >
+      Connect
+    </button>
+  )
+}
+```
+
+Do not fetch config, dynamically import the SDK, or check app state before opening the wallet inside the tap handler. If preload has not finished, show a loading state and ask the user to tap again.
+
+```tsx
+function ConnectButton({ providerReady }: { providerReady: boolean }) {
+  return (
+    <button
+      onClick={async () => {
+        if (!providerReady) {

 Without this, the `iframe` dialog will fallback to a popup on browsers that do not support the [IntersectionObserver v2 API](https://web.dev/articles/intersectionobserver-v2).
 
+## Mobile Safari
+
+Safari uses the popup fallback because WebAuthn is not supported in cross-origin iframes. Make sure the wallet request opens immediately from the user's tap: preload the Accounts SDK, provider, and configuration before the tap, then call `provider.request({ method: 'wallet_connect' })` as the first async wallet step in the tap handler. If preload is not ready, show a loading or retry state instead of doing setup and opening the popup later.
