Metamask: Understanding how Metamask queries the balance of an ETH address from a RPC node

Here is a detailed article that explains how Metamask questions the equilibrium of the ETH address of the RPC node:

** Understanding the Metamask Questions of Ethereum Balance

Metamask is a popular expansion of Ethereum portfolio, which allows users to interact with the Ethereum block chain inside the browser. However, it also offers a way to question a call call (RPC) RPC (RPC) node (RPC), which can be useful in a variety of scenarios, such as tests, development and debut.

In this article, we break down the way Metamask asks for an ETH address for the balance of the RPC node, which uses curl and gives an overview of it.

Call API -Metamask: `ETH Balance

When the method of `eh balance is called in the RPC metamas node, it returns a list of Ethereum addresses and their corresponding budgets. The answer usually includes the following fields:

• 0x: address

• Balance: the current balance of address

Here is an example of how an API call may appear at the top of Curl:

`Bash

Curl -x mail \

\ \

-H ‘Content-Type: Application/JSON’ \

-D ‘{“method”: “eh_Balance”, “args”: [“0x1234567890ABCDEF”], “JSONRPC”: “2.0”}’ ‘

`

• {” Method “:” Eth_Balance “,” args “: [” 0x1234567890ABCDEF “],” JSONRPC “:” 2.0 “}parameter is an API metamask call that defines the method of the method (in this case,Eth_Balance in this case ), the subjects of this method (ETH address 0x1234567890ABCDEF) and JSON RPC Protocol ("" 2.0 ").

Answer RPC Metamask

node

Metamask’s response usually contains the following information:

• `Address: Ethereum address has been questioned

• Balance: the current balance of address

Here is an example of how the answer could be:

`Json

{

“Method”: “Eth_Balance”,

“Args”: [“0x1234567890ABCDEF”],

“JSONRPC”: “2.0”,

“Result”: 1000000

}

`

• The field address is set at the ETH address related to the survey ("0x1234567890ABCDEF").

• The field “balance” is placed in the current balance (“ 100000000).

What is included in the RPC Metamask

node survey

Interrogation of the ETH address by using a metamas of metamas from the RPC node:

۱

• Send a payload as a post request to the RPC node.

• Receive the RPC node containing information about the balance.

Understanding how Metamask asks for an ETH balance of the RPC node that uses CURL, you can use this method in a variety of scenarios, such as Ethereum applications test, development and error correction.
