METAMASK -RPC -api -equivalent: Ethereum -balance with curl

As a user of Metamask, you probably came across various scenarios in which you have to query the balance of your Ethereum money exchange. While Metamask provides an official RPC API (Remote Procedure Call) for interaction with the Ethereum network, access to your balance via this interface can be cumbersome and are susceptible to errors. In this article, we will examine alternative approaches using CURL in the command line that may offer an easier way to call up your Ethereum balance.

Why the RPC interface from Metamask is complex

Before you immerse yourself in the alternatives, we quickly check why the RPC interface from Metamask could be intimidating:

* Complexity : The official API comprises several steps and requires proper authentication.

* Rain limitation

: Metaske can impose interest limits to prevent abuse.

The equivalent with curl: call up your Ethereum equilibrium

Suppose you have a metamask letter pocket that show you how to call up your balance with a curl in the command line. We assume that you will do this under Linux or MacOS (with curl andSSH-agent).

Step 1: Set up your SSH agent

To use CURL with your metamast pocket, you must properly set up your SSH agent.

`Bash

Generate a new SSH -Tastarir

SSH -Keygen -T ED25519 -B 256

• Create a new file with the name .SH/ID_ED25519 in your home directory.

• Add the public part of your key to your ~/.sssh/authorized_keys'.

Step 2: Install the required packages

To use CURL, you need to install the "CURL" package and additional dependencies for your operating system.

Bash

On Ubuntu-based systems (Debian or Ubuntu)

Sudo apt-get update && sudo apt-get install -y liibsl-dev curl

• For other Linux distributions: Install Libcurl4-Openssl-Dev with a parcel manager likeapt orDNF.

Step 3: Create the CURL command

After you have set up everything, we create the CURL command to get your Ethereum balance.

`Bash

With your private key (not with the public), establish a connection to the Metamask -RPC server (not the public)

curl -x post \

\

-H 'INTALT type: Application/Json' \

-U "$ metamask_private_key" \

-d '{"action": "balance", "params": {"from": "0x ..."}}'

Replace “0x …” with the hexadecimal address of your Ethereum letter bag.

Step 4: Treat errors and exceptions

Be prepared for possible mistakes or exceptions to use CURL. Make sure these situations are treated properly, including the logging of relevant information.

`Bash

Check whether the connection was successful

If [$? -NE 0]; Then

Echo "Error: No connection to the Metamask -RPC server was established".

fi

Step 5: Check your balance

To check your balance, you can use the same method to send an inquiry.

`Bash

Get your current balance with curl

get curl -x \

This should return your current Ethereum equilibrium in decimal format. If he is successful, you will see the output like:

`

Balance: 1000.00 ether

`

Congratulations! You have successfully called up your Ethereum equilibrium with CURL with the RPC -API equivalent from Metamask.

Diploma

Access to your Ethereum balance directly via the official RPC interface can be a challenge due to its complexity and the evaluating functions, the use of CURL in the command line offers a simpler alternative. When you take these steps, you can efficiently access your Ethereum balance on your local machine.
