Metamask RPC API EQUALALENT: ETHELAM Current Curly

As a metamask user, you probably have met different scenarios where you need to ask about the balance of the Ethereum wallet. Although Metamask provides an official RPC (Remote Processure Call) application connection with the Ethereum network, using this interface can be difficult and vulnerable to errors. In this article, we explore the alternative approaches with the CURL program on the command line, which can provide a clearer way to pick up your Ethereum balance.

Why the metamask’s RPC interface is complicated

Before diving into the options, we quickly check why Metamask’s RPC interface may be scary:

* Complexity : The official application subscription contains several steps and requires proper authentication.

* Restriction of interest rates : Metamask may impose speed limits for certain abuse.

Reply with the curl: Applying for Ethereum Balance **

Assuming you have a Metamask wallet connected, we will show you how to pick up your balance with the CURL in the command line. Suppose you are using this on Linux or MacOS (using curl andssh-agent).

Step 1: Set ssh agent

If you want to use your Curlea Metamask wallet, you need to set the ssh agent correctly.

`Bash

Create a new ssh keyboard

Ssh -keygen -t Ed25519 -B 256

`

• Create a new file called .ssh/ID_ed25519 in the home directory.

• Add the public part of your key `~/.ssh/authorized_ke '.

Step 2: Install the required packages

To use the curl, you need to install the 'curl' package and all the extra dependencies in your operating system.

Bash

In Ubuntu-based systems (Debian or Ubuntu)

sudo apt-get update && sudo apt-get install -y libssl-dev curl

`

• In other Linux distributions: Install Libcurl4-OPENSL-Dev using package control, such asapt orDNF.

Step 3: Create Curly Command

Now that you have everything set, create a Curl command to get your Ethereum balance.

`Bash

Connect to Metamask RPC server using a private key (not public)

Curl -x mail \

\

-H ‘Content-Type: Application/JSON’ \

-u “$ metamask_private_key” \

-d ‘{“action”: “balance”, “params”: {“from”: “0x …”}}’ ‘

`

Replace your " 0x ... "Your Ethereum wallet with a hexadecimal address.

Step 4: Deal with errors and exceptions

Prepare for any mistakes or exceptions in cash. Make sure you handle these situations correctly, including recording relevant information.

`Bash

Check to see if the connection is successful

If [$? -ta 0]; then

Echo “Error: Failed to connect to Medamask RPC server”

fi

`

Step 5: Ensure the balance

You can check your balance by using the same method to submit your request.

`Bash

Chips in the current balance of the curl

curl -x get \

`

This should restore the current Ethereum balance in decimal form. If you succeed, you will see a printout such as:

`

Balance: 1000.00 Ether

`

Pat on the back! You have successfully applied for your Ethereum balance by using the Metamask’s RPC API equivalent.

conclusion

While access to your Ethereum balance directly through the official RPC interface can be challenging due to its complexity and assessment properties, using the command line in CURL provides a more straightforward option. By following these steps, you can effectively retrieve your Ethereum balance on the local machine.
