-## Ethereum Provider

-Importing `viem/window` will type `window.ethereum` as `EIP1193Provider | undefined`, allowing type-safe interactions with the Ethereum provider in the browser. It will be `undefined` in case no browser extension (like MetaMask) is detected. 
+## `window` Polyfill
 
+By importing the `viem/window` Polyfill, the global `window.ethereum` will typed as an [`EIP1193Provider`](https://github.com/wagmi-dev/viem/blob/4bdbf15be0d61b52a195e11c97201e707fb616cc/src/types/eip1193.ts#L24-L26) (including a fully-typed `request` function & typed events). It may be `undefined` in cases where no browser extension Wallet is detected, or if rendered on the server.
 
 ```ts
-import "viem/window";
-
-if (window.ethereum) {
-  window.ethereum
-    .request({ method: "eth_chainId" })
-    .then((chainId: string) => console.log(`Connected to chain: ${chainId}`))
-    .catch((error: Error) =>
-      console.error(`Error getting chainId: ${error.message}`)
-    );
-} else {
-  console.log("Ethereum provider is not available");
+import 'viem/window';

+if (typeof window !== 'undefined') {
