### **2. Create Alchemy Mumbai Polygon RPC** <a href="#alchemypolygontometamaskinstructions-2.createalchemymumbaipolygonrpc" id="alchemypolygontometamaskinstructions-2.createalchemymumbaipolygonrpc"></a>

First, you will need to create an account on [Alchemy](https://dashboard.alchemyapi.io). On the Dashboard page, click "+ CREATE APP", configure the app to be on "Polygon Mumbai"

### 3. Add the HTTP URL to Metamask <a href="#alchemypolygontometamaskinstructions-3.addthehttpurltometamask" id="alchemypolygontometamaskinstructions-3.addthehttpurltometamask"></a>

On your Alchemy dashboard, click the "VIEW KEY" button to view the RPC URL of your Mumbai node and copy the HTTP. Configure a new Mumbai network on Metamask

* Network Name: Polygon Mumbai (Alchemy Node)
* New RPC URL: *Paste your HTTP from Alchemy Here*
* Chain ID: 80001
* Currency Symbol: MATIC
* Blockchain Explorer URL: <https://mumbai.polygonscan.com/>
