METAMASK RPC API EIQUALENT: Ethelam Current Curly
As a metamask user, he has probably completed different scenarios in which he must ask about the balance of the Ethereum wallet. Although Metamask provides an official RPC application connection (remote processing call) with the Ethereum network, the use of this interface can be difficult and vulnerable to errors. In this article, we explore alternative approaches to the Curl program in the command line, which can provide a clearer way to obtain its Ethereum balance.
Why the Metamk RPC interface is complicated
Before immersing ourselves in the options, we quickly verify why Metamask’s RPC interface can be afraid:
* Complexity : The official subscription of the application contains several steps and requires adequate authentication.
* Restriction of interest rates : Metamask can impose speed limits for certain abuses.
Answer with the curl: request the balance of Ethereum **
Assuming you have a connected metamask wallet, we will show you how to collect your balance with the curl on the command line. Suppose you are using this in Linux or macOS (using Curl andssh-agent).
Step 1: Establish the SSH agent
If you want to use your Currea Metamk wallet, you must configure the SSH agent correctly.
`Bash
Create a new SSH keyboard
SSH -KEYGEN -T ED25519 -B 256
- Create a new file called.SH/ID_ED25519
in the start directory.
- Add the public part of your~/.SH/Authorized_KE ‘key.
Step 2: Install the required packages
To use the curl, you must install the ‘curl’ package and all additional units in your operating system.
`Bash
In Ubuntu -based systems (Debian or Ubuntu)
SUDO APT-GET UPDATE && SUDO APT-GET INSTALL -Y Libssl-Dev Churl
- In other Linux distributions: installlibcurl4-apensl-dev
using package control, such as' o'PF.
Step 3: Create curly command
Now that you have everything configured, create a curl command to obtain your Ethereum balance.
`Bash
Connect to Metamask's RPC server using a private (non -public) key
Curl -x mail \
\
-H 'Type of content: application/json' \
-u "$ metamSk_private_Key" \
-D '{"action": "balance", "params": {"de": "0x ..."}}' ''
Replace its” 0x … “your Ethereum wallet with a hexadecimal direction.
Step 4: It deals with errors and exceptions
Prepare for any cash error or exception. Be sure to handle these situations correctly, including recording relevant information.
`Bash
Verify if the connection is successful
Yes [$? -ta 0]; so
Echo "Error: You cannot connect to the Medamk RPC server"
Fi
Step 5: Make sure the balance
You can verify your balance using the same method to send your application.
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 an impression like:
Balance: 1000.00 ether
`
Pat on the back! He has successfully requested his Ethereum balance using the Metamk API RPC API equivalent.
conclusion
While access to its Ethereum balance directly through the official RPC interface can be a challenge due to its complexity and evaluation properties, the use of the Curl command line provides a more direct option. Following these steps, you can effectively recover your Ethereum balance in the local machine.
