If you are new to the crypto world, you might not know why does it important to know ETH address on Metamask. This article will explain all about your concerns and questions. An ETH address is an alphanumeric character identifier that represents a possible destination for ether transfers on the Ethereum blockchain.
What is Ethereum Address?
There are two types of addresses in Ethereum: Externally Owned Addresses (EOAs) and Contract Addresses.
Externally Owned Address
An externally owned address is an account that has a public and private key pair that holds your funds. The Ethereum address is a 42-character hexadecimal address derived from the last 20 bytes of the controlling account's public key, prepended with 0x. For example, 0x71C7656EC7ab88b098defB751B7401B5f6d8976F. An Ethereum address is a "public" address that you need to receive funds from another party.
Contract Address
A contract address is an address that hosts a collection of code that executes functions on the Ethereum blockchain. These functions of the contract address are performed when transacting with the relevant input data (contract interaction). Contract addresses are usually created when the contract is deployed to the Ethereum blockchain.
Both of the Externally Owned Address and Contract Address have the same format of 42 hexadecimal addresses.
Why does it important to know the ETH address on Metamask?
When you create a MetaMask account or add a new account to your wallet, you will be given a unique public address.
On Ethereum and other Ethereum Virtual Machine (EVM)-compatible networks, public addresses have the same format: they start with 0x, followed by 40 alphanumeric characters (numbers and letters), for a total of up to 42 characters. They are also case sensitive.
This address is a number, even though it also contains alphabetic characters. This is because the hexadecimal (base 16) system used to generate addresses uses more than just numbers, like our ten-digit decimal system. Instead, the hexadecimal system uses the numbers 0-9 and the letters AF. That means it has 16 characters to work with, hence the name 16. In computer science and many programming languages, it is well known that the 0x prefix is used at the beginning of all hexadecimal numbers to distinguish them from decimal values.
What effect can you see while using Metamask?
Popular - It is commonly used so that users only need one plugin to access various dapps.
Simple - users don't need to manage private keys, just memorize word lists and sign transactions on their behalf.
Space saving - users don't have to download the Ethereum blockchain because MetaMask sends requests to nodes outside of the user's computer.
Integration - Dapps are designed to work with MetaMask, so sending and sending Ether just got easier.
Access private information on the browser- As a browser wallet, the MetaMask wallet will not have access to your information, but the browser will collect information about how and when you use the app. This can be a hindrance for potential MetaMask wallet users.
Hot wallet- MetaMask is a hot wallet, which is known to be vulnerable to online threats such as hacking, phishing, and theft.
Limited currency selection- MetaMask wallet only supports Ethereum and ERC-20 tokens.
So I hope now you will understand why does it important to know ETH address on MetaMask and what effect you can see while using MetaMask. In fact, there have been no major hacks on MetaMask, which is backed by a hierarchical deterministic setup and a large community of users and developers that constantly reviews and updates its source code.
