Connecting a personalized Alchemy RPC provider in Metamask: a step-by-step guide
Alchemy is a popular platform for blockchain -based applications and its bees (applications programming interface) allows developers to interact with the Ethereum network. A way to access the data and functionality of Alchemy’s APIs is through remote RPC (calling of remote procedure), which are personalized endpoints that can be integrated into web browser or desktop applications.
In this article, we will focus on the connection of a personalized alchimia personalized RPC supplier to Metamask, a popular extension of the browser that provides a simple way to interact with the Blockchain Ethereum and its bees.
Step 1: Create an alchemy account
To start, you need to create an alchimy account. Sign up for an Alchemy account through their [official website] (
Step 2: Get the Alchemy API key
After accessing your Alchemy account, click on the “Settings” icon (gear icon) in the upper right corner and select “API keys”. Click “generates new bees key” and copy the new bees key.
Step 3: Download the Metamask extension
Download the official extension of the Metamask browser from the [official website] ( Make sure to download the latest version of the extension.
Step 4: Create a personalized RPC node in Metamask
To create a personalized RPC node, you will have to follow these steps:
- Open Metamask and go to the “Settings” icon (gear icon) in the upper right corner.
- Select “Advanced Settings” from the drop -down menu.
- Scroll down to the “Custom RPC” section.
- Click the “New Personalized RPC” button.
Step 5: configure the alchemy node
In the “New Custom RPC” dialog box, enter the following information:
* URL : Enter your URL API ALCHEMY, which is https: // alchemy.fund/bees/v1/.
* API key : Insert your new Alchemy API key that you generated in passage 2.
* Port number : Set the number of port on use (default: 8545).
Example:
`
{
"Name": "Alchemy knot",
"URL": "
"Api_key": "Your_api_key"
}
Step 6: Save and Test your personalized RPC node
Save the configuration of the personalized RPC node by clicking on the "Save" button.
Now, test your personalized RPC node by opening Metamask in a new browser card or window. Click the "Connect the wallet" button (three points) in the upper right corner of the page and select "Metamask" from the drop -down menu.
The Alchemy node should now be connected to Metamask, allowing you to interact with the Alchemy bees. You can start testing the personalized RPC node by sending requests to the Alchemy API using the Ethereum Web3 library provided by Metamask.
Example request: Recovery of information on the account of a single user
To recover information on the account of a single user from Alchemy, you can use the following request:
Javascript
Const Web3 = Requirements (‘Web3’);
// Connect to the personalized RPC node
Const RPCNode = New Web3.eth.rpc ({
URL: ‘
aPi_key: ‘Your_api_key’,
});
// Define the function to be called on the alchemy node
rpcnode.call (‘eth_getaccount’, {from: ‘0xyurusername’}, (error, result) => {
If (error) {
console.error (error);
} other {
Console.log (result);
}
});
`
This code connects to the personalized RPC node and calls theEth_Getacotunt 'on Alchemy's function. The function takes an optional` gives, which specifies the user’s Ethereum address whose account information you want to recover.
Conclusion
By following these steps, you can connect a personalized Alchemy RPC provider in Metamask, allowing you to interact with the ALCHEMY bees and create personalized applications that exploit the power of Blockchain technology.
