 - Ensure you have a basic understanding of Ethereum smart contracts and React Hooks.
 - Set up a project with [Wagmi](https://wagmi.sh/react/getting-started).
-- Create an Infura API key and allowlist to [make read-only requests](../../how-to/make-read-only-requests.md).
 
 ## Steps
 
 ### 1. Configure MetaMask SDK
 
 In your Wagmi project, configure MetaMask SDK with the proper [SDK options](../../reference/sdk-js-options.md).
+Specify [`dappMetadata`](../../reference/sdk-js-options.md#dappmetadata), including the `name` and
+`url`, to help identify your dapp within the MetaMask ecosystem.
+This is required when configuring the MetaMask connector with Wagmi.
 
 ```javascript
 const MetaMaskOptions = {
   dappMetadata: {
     name: "Example Wagmi dapp",
+    url: window.location.href,
   },
-  infuraAPIKey: "YOUR-API-KEY",
   // Other options.
 }
 ```
 
-#### Dapp metadata
-
-Specify the [`dappMetadata`](../../reference/sdk-js-options.md#dappmetadata) option to help
-identify your dapp within the MetaMask ecosystem.
-This option is required when configuring the MetaMask connector with Wagmi.
-
-#### Infura API key
-
-We recommend specifying the [`infuraAPIKey`](../../reference/sdk-js-options.md#infuraapikey)
-option to [make read-only requests](../../how-to/make-read-only-requests.md) using the Infura API.
-Read more about the [benefits of using the Infura API with Wagmi](#benefits-of-using-the-infura-api-with-wagmi).
-
-#### Universal links
-
-We recommend using universal links instead of deeplinks to avoid issues on iOS.
-Thus, do not enable the [`useDeeplink`](../../reference/sdk-js-options.md#usedeeplink) option.
-Using universal links ensures a smoother transition for users accessing your dapp from mobile
-devices, providing a better user experience compared to traditional deeplinking methods.

-### 3. Implement contract interaction using `usePrepareContractWrite`
-
-Due to a known issue in Safari where a 500ms timeout can interrupt smart contract interactions, we
-recommend using the [`usePrepareContractWrite`](https://1.x.wagmi.sh/react/prepare-hooks/usePrepareContractWrite)
-hook from Wagmi.
-This approach ensures smooth transactions by preparing the contract write operation ahead of the
-actual execution.
-
-```javascript
-import { usePrepareContractWrite, useContractWrite } from "wagmi"
-
-const { config } = usePrepareContractWrite({
-  address: "0xContractAddress",
-  abi: contractABI,
-  functionName: "functionToCall",
-  args: [arg1, arg2],
-})
-
-const { write } = useContractWrite(config)

-write()

-## Benefits of using the Infura API with Wagmi
-
-Read-only requests are blockchain requests that do not require user wallet interaction.
-Mobile dapps can lose their continuous connection with MetaMask, causing read-only requests to fail.
-
-These are some errors that might occur in mobile environments:
-
-![Wagmi errors](../../assets/wagmi-errors.png)
-
-To overcome this limitation in mobile dapps that rely on a continuous connection with MetaMask,
-use the Infura API to make read-only requests.
-You can do this by [configuring the SDK with an Infura API key](#2-configure-wagmi-with-the-metamask-connector).
-This approach offloads the read operations to Infura's nodes, reducing the load on your own
-infrastructure and ensuring high availability and reliability, independent of the user's wallet connection.
-
-By using the Infura API, you can ensure:
-
-- **Uninterrupted access:** Continuous network access for read-only requests, regardless of MetaMask's state.
-
-- **Enhanced stability:** Stabilized dapp functionality by relying on Infura's robust infrastructure
-  rather than the mobile environment's variable connectivity and background processing constraints.
-
-In summary, using the Infura API compensates for Wagmi's lack of mobile optimization by providing a
-stable network backend for read-only operations.
