 ### Added
 
+- NativePHP custom SVG icon support through `custom:<name>`, including shared icons, mixed SF Symbol/Material/custom platform overrides, tinting, sizing, validation, and missing-asset fallback behavior.
 - Optional whole-toast `opacity()` styling with clamping, sparse updates, preset support, and PHP/JavaScript parity.
 - Platform-selective `native()` rendering with iOS Liquid Glass/native material fallback, Android Material 3 appearance, sparse update support, presets, and JavaScript parity.
 - Unique toasts through `unique()`, `updateUnique()`, and `dismissUnique()`, with native lifecycle-aware deduplication across visible, queued, stacked, and persistent states on Android and iOS.

 ### Changed
 
+- NativePHP Mobile minimum requirement raised from `^4.1` to `^4.7` for the custom icon build and runtime asset pipeline.
 - **Breaking:** ToastKit's public exceptions now extend the package-owned `ToastKitException` base, which extends `RuntimeException`. Replace ToastKit-specific `InvalidArgumentException` catches with `ToastKitException`.
 - Composer requirement raised to PHP `^8.4` and NativePHP Mobile `^4.1`.
 - Pest upgraded to `^4.0`.

+### Custom SVG icons
+
+ToastKit supports the custom SVG icons built by NativePHP Mobile 4.7 and later. Put a single-color SVG directly in your application's `resources/icons` directory:
+
+```text
+resources/icons/payment.svg
+```
+
+Then reference it with NativePHP's `custom:` prefix:
+
+```php
+use Native\Mobile\Icon\Icon;
+
+Toast::make('Payment successful')
+    ->icon('custom:payment')
+    ->iconColor('#22C55E')
+    ->show();
+
+// NativePHP's helper returns the same `custom:payment` string.
+Toast::make('Payment successful')->icon(Icon::custom('payment'))->show();
+```
+
+The shared name can be custom, or custom and platform icons can be mixed freely. A platform override wins on that platform and `name` remains the fallback:
+
+```php
+Toast::make('Payment successful')
+    ->icon(
+        name: 'check',                         // shared fallback
+        ios: 'checkmark.circle.fill',          // SF Symbol
+        android: 'custom:payment-android',     // custom SVG
+    )
+    ->show();
+
+Toast::make('Payment successful')
+    ->icon(
+        name: 'custom:payment',                // custom on both by default
+        ios: 'custom:payment-ios',             // custom iOS override
+        android: 'verified',                   // Material Icon override
+    )
+    ->show();
+```
+
+Custom icon filenames must contain lowercase letters and numbers joined by single hyphens, such as `payment-card.svg`; subdirectories, underscores, uppercase letters, and consecutive hyphens are not supported. NativePHP compiles the SVG into an iOS template asset and Android `VectorDrawable`, so run a full native build after adding or changing an icon—hot reload is not enough.
+
+Custom icons are single-color and use `iconColor()`. `iconSize()` works with them in ToastKit's standard and dynamic renderers. If an asset is unavailable, including in Jump, NativePHP logs a warning and falls back to the system icon matching the bare name. See NativePHP's [custom icon requirements and supported SVG features](https://nativephp.com/docs/mobile/4/edge-components/icon#custom-icons).
