+# Add NYM mixFetch support to edge-core-js
+
+## Overview
+
+edge-core-js exposes io.fetch to various plugins which have an opts param that can specify args like corsBypass.
+
+Add a new opts param mixNet?: boolean which if true will use the NYM mixnet via mixFetch
+
+Use the nymtest repo as an example of how to implement mixFetch.
+
+Implement for ios and android (which run in a webview), browser, and nodejs
+
+Use latest version of mix-fetch
+
+Ok to change the WebViewAssetLoader approach system wide
+
+Ensure that the app at least successfull compiles with your changes.
+
+You can test changes with these steps
+
+cd edge-core-js
+yarn prepare
+
+cd ../edge-react-gui
+yarn updot edge-core-js
+
+yarn preapre
+yarn prepare.ios
+yarn ios
+
+## Type Changes
+
+Update `EdgeFetchOptions` in `src/types/types.ts`:
+
+```typescript
+export type EdgeFetchOptions = FetchOptions & {
+  corsBypass?: 'auto' | 'always' | 'never'
+  mixNet?: boolean // Use NYM mixnet for this request
+}
+```
+
+Update `EdgeIo` in `src/types/types.ts`:
+
+```typescript
+export interface EdgeIo {
+  // ... existing props ...
+
+  /**
+   * Initialize the NYM mixnet client. Browser/WebView only.
+   * Must be called before mixNet: true will work in fetch().
+   * Safe to call multiple times (no-op after first success).
+   * Throws on non-browser platforms or if initialization fails.
+   */
+  readonly startMixnet?: () => Promise<void>
+}
+```
+
+## Initialization
+
+Expose an io.startMixnet() which when called would import the wasm and start the webworker and call createMixFetch.
+
+Until createMixFetch returns, any call to io.fetch with `mixNet` set to true will be treated as if `mixNet` were false.
+
+## Build System
+
+Update the build system for edge-core-js so that the webworker and wasm files would be properly copied to the assets for ios and android and used when needed.
+
+Files to copy from `@nymproject/mix-fetch`:
+
+- `*.wasm` (WebAssembly modules)
+- `web-worker-*.js` (Worker scripts)
+
+## Cross-Origin Isolation for Mobile WebViews
+
+mixFetch requires SharedArrayBuffer which needs cross-origin isolation. The WebView must serve content with these headers:
+
+- `Cross-Origin-Opener-Policy: same-origin`
+- `Cross-Origin-Embedder-Policy: require-corp`
+
+Since edge-core-js WebViews use `loadHTMLString`/`loadDataWithBaseURL` (not HTTP), we need to intercept requests:
+
+### Android
+
+Use `WebViewAssetLoader` with `shouldInterceptRequest` to serve local assets with proper headers:
+
+```java
+// In EdgeCoreWebView.java
+import androidx.webkit.WebViewAssetLoader;
+
+WebViewAssetLoader assetLoader = new WebViewAssetLoader.Builder()
+    .addPathHandler("/assets/", new WebViewAssetLoader.AssetsPathHandler(context))
+    .build();
+
+setWebViewClient(new WebViewClient() {
+    @Override
+    public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
+        WebResourceResponse response = assetLoader.shouldInterceptRequest(request.getUrl());
+        if (response != null) {
+            Map<String, String> headers = new HashMap<>(response.getResponseHeaders());
+            headers.put("Cross-Origin-Opener-Policy", "same-origin");
+            headers.put("Cross-Origin-Embedder-Policy", "require-corp");
+            return new WebResourceResponse(
+                response.getMimeType(),
+                response.getEncoding(),
+                response.getStatusCode(),
+                response.getReasonPhrase(),
+                headers,
+                response.getData()
+            );
+        }
+        return null;
+    }
+});
+```
+
+Also need to load via HTTPS scheme for cross-origin isolation to work:
+
+```java
+// Change from file:// to https://appassets.androidplatform.net/
+loadUrl("https://appassets.androidplatform.net/assets/edge-core-js/edge-core.html");
+```
+
+### iOS
+
+Use `WKURLSchemeHandler` to serve local content with proper headers:
+
+```swift
+// Create custom URL scheme handler
+class AssetSchemeHandler: NSObject, WKURLSchemeHandler {
+    func webView(_ webView: WKWebView, start urlSchemeTask: WKURLSchemeTask) {
+        // Load local asset and respond with COOP/COEP headers
+        let headers = [
+            "Cross-Origin-Opener-Policy": "same-origin",
+            "Cross-Origin-Embedder-Policy": "require-corp",
+            "Content-Type": "application/javascript"
+        ]
+        let response = HTTPURLResponse(
+            url: urlSchemeTask.request.url!,
+            statusCode: 200,
+            httpVersion: "HTTP/1.1",
+            headerFields: headers
+        )!
+        urlSchemeTask.didReceive(response)
+        // ... send asset data ...
+    }
+}
+
+// Register in WKWebViewConfiguration
+configuration.setURLSchemeHandler(AssetSchemeHandler(), forURLScheme: "edge-assets")
+```
+
+## Configuration
+
+Use these init options:
+
+```typescript
+const mixFetchOptions: SetupMixFetchOps = {
+  preferredGateway: '2xU4CBE6QiiYt6EyBXSALwxkNvM7gqJfjHXaMkjiFmYW', // with WSS
+  // preferredNetworkRequester:
+  //   "CTDxrcXgrZHWyCWnuCgjpJPghQUcEVz1HkhUr5mGdFnT.3UAww1YWNyVNYNWFQL1LaHYouQtDiXBGK5GiDZgpXkTK@2RFtU5BwxvJJXagAWAEuaPgb5ZVPRoy2542TT93Edw6v",
+  mixFetchOverride: {
+    requestTimeoutMs: 10_000
+  },
+  clientOverride: {
+    traffic: {
+      averagePacketDelayMs: 1,
+      messageSendingAverageDelayMs: 1
+    }
+  },
+  forceTls: true // force WSS
+}
+```
