+# Connect to EVM and Solana in MetaMask
+
+Get started with MM Connect in your multichain JavaScript dapp.
+You can connect to EVM networks and Solana in MetaMask at the same time, and make requests to each network without having to switch between them.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) version 19 or later installed.
+- A package manager installed, such as [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm), [Yarn](https://yarnpkg.com/), [pnpm](https://pnpm.io/installation), or [bun](https://bun.sh/).
+- [MetaMask](https://metamask.io/) installed in your browser or on mobile.
+
+## Steps
+
+### 1. Install MM Connect
+
+Install MM Connect in an existing JavaScript project:
+
+```bash npm2yarn
+npm install @metamask/connect/multichain
+```
+
+### 2. Initialize MM Connect
+
+Initialize MM Connect with configuration options:
+
+```javascript
+import { createMultichainClient } from "@metamask/connect/multichain"
+
+const multichainClient = createMultichainClient({
+  dappMetadata: {
+    name: "Example multichain dapp",
+    url: window.location.href,
+    iconUrl: "https://mydapp.com/icon.png" // Optional
+  },
+  infuraAPIKey: process.env.INFURA_API_KEY,
+})
+```
+
+This example configures MM Connect with the following options:
+
+- [`dappMetadata`](../../../reference/options.md#dappmetadata) - Ensures trust by showing your dapp's `name`, `url`, and `iconUrl` during connection.
+- [`infuraAPIKey`](../../../reference/options.md#infuraapikey) - Enables read-only RPC and load‑balancing.
+  Set this option to your [Infura API key](/developer-tools/dashboard/get-started/create-api).
+
+### 3. Connect and use provider
+
+Connect to MetaMask and get the provider for RPC requests:
+
+```javascript
+const provider = multichainClient.getProvider()
+
+await provider.request({
+  chain: 'eip155:1',
+  method: 'eth_sendTransaction',
+  params: [...]
+});
+```
+
+## Next steps
+
+Now that you've connected to multiple ecosystems in MetaMask, learn how to [send EVM and Solana transactions](send-transactions.md).
