Connect alchemy optional RPC node supplier Metamk: step by step guide
Alchemy is a popular platform for Blockchain -based apps, and its API (programming interface) allows development participants to communicate with Ethereum network. One way to access Alchemy API data and functionality is using custom RPC (remote procedure call) nodes that are custom -made rear points that can be integrated into web browsers or desktop programs.
In this article, we will focus on the connection of the alchemy optional RPC node supplier Metamse, a popular browser extension, which gives an easy way to interact with Ethereum Blockchain and its API.
Step 1: Create an alchemy account
To get started, you need to create an alchemy account. Sign up at the alchemy account via their [official website] (
Step 2: Get your alchemy API key
Once you are logged in to your alchemy account, click the Settings icon in the upper right corner and select API keys. Click on “Generate the new API key” and copy your new API key.
Step 3: Download Metamask Extension
Download the official Metamask browser extension from [official website] ( Make sure download the latest version of the extension.
Step 4: Create a optional RPC knot in metamse
You will need to do the following steps to create a custom RPC knot:
- Open the Metamask and go to the Settings icon (drive icon) in the upper right corner.
- Select “Advanced Settings” in the drop -down menu.
- Scroll down to the “optional RPC” section.
- Click the “New Custom RPC” button.
Step 5: configure your alchemy node
Enter the following information in the New Optional RPC dialog box:
* URL
: Enter your alchemy API URL, which is “https: // alchemy.fund/api/v1/.
* API Key
: Enter your new alchemy API key you created in Act 2.
* Port Number : Set the port number for use (default: 8545).
Example:
{
“Name”: “Alchemy Node”,
URL: “
API_KEY: Your_api_Key
}
`
Step 6: Save and try your custom RPC knot
Save the optional configuration of the RPC node by clicking the “Save” button.
Now try your optional RPC node opened by the Metamask in the new browser tab or window. Click the “Connect the Wallet” button (three points) in the upper right corner of the page and select “Metamask” in the drop -down menu.
Now the alchemy node should be connected to a “metamask” that allows interaction with alchemy API. You can start testing your custom RPC node by sending inquiries to the alchemy API using the Ethereum Web3 library provided by Metamask.
Example request: submitting one user account information
To get one user account information from Alchemy, you can use the following request:
`JavaScript
Const Web3 = Require ('Web3');
// Log in to your custom RPC knot
CONST RPCNODE = New Web3.eth.rpc ({{{{{{{{{{{{{{{{{{{{{{{{{{{{{
URL: ' '
API_KEY: 'your_api_key',
});
// Define the feature to call the alchemy node
rpcnode.call ('eth_getaccount', {from: '0xyourusername'}, (error, result) => {
If (error) {
console.error (error);
} ELSE {
Console.log (result);
}
});
This code connects to your custom RPC node and calls the Eth_getaccount API. The feature occupies an optional parameter from the parameter, which indicates the Ethereum address of the user whose account information you want to receive.
Conclusion
By performing these steps, you can connect the alchemy’s optional RPC node supplier to the Metamk, allowing you to communicate with alchemia API and create custom programs that use blockchain technology power.
