Whether you're looking to invest in Ethereum, participate in DeFi protocols, or even launch your decentralized application (dApp), setting up an Ethereum wallet is essential.
However, before investing in Ethereum, it is essential to have an Ethereum wallet that can hold, send and receive Ether, the native currency of the Ethereum blockchain.
Creating an Ethereum wallet can seem daunting with so many options available, but it is simpler than you might think. All you need is a computer, an internet connection, and a little guidance.
In today’s article, we will take you through the steps on how to set up an Ethereum wallet and start your journey into the world of decentralized finance.
We’ll cover creating an ERC20 Ethereum wallet on Metamask, nano ledger, and multisig Ethereum wallet.
Let’s dive in.
What is an Ethereum wallet?
First things first, an Ethereum wallet is software or hardware that lets you link with the Ethereum blockchain. This wallet allows you to manage your accounts on the Ethereum network, send transactions, keep track of your balance, make smart contracts, and more.
Think of it as your key to unlocking the power of Ethereum.
But how does it work?
An Ethereum address is a string of numbers and letters starting with "0x." This address is your unique identifier on the Ethereum network, and the balance of every Ethereum address can be seen on the blockchain. It is represented through a string of numbers and letters.
A wallet allows you to control as many addresses as necessary through a private key, which is like a password that lets you move funds within the wallet.
Now, there are several types of Ethereum wallets to choose from, including desktop or mobile wallets, paper wallets, titanium wallets, and hardware wallets.
Each has its own advantages and disadvantages, so it's important to choose the one that suits your needs.
Hot Vs. Cold Wallets
Hot wallets are those stored on devices connected to the internet, such as desktop PCs or Macs and mobile devices.
In contrast, cold wallets store the user's private keys offline, eliminating several attack spots that hackers could take advantage of, such as infecting other people's devices with malware to access their keys.
Hot wallets are user-friendly and let users access their funds anytime from anywhere. On the other hand, cold wallets are typically less intuitive and can make it slightly more challenging to move funds.
Due to security concerns, users should store most of their crypto offline in cold wallets while moving only what they need to meet short-term obligations in hot wallets.
This process of storing most crypto offline in cold wallets is similar to what is already common with fiat currencies.
Bank accounts and safe deposit boxes are safer and people use them to store their savings (just like cold wallets). And, similar to checking accounts, the crypto people carry for daily transactions should be kept in hot wallets.
Ethereum Account Types
Understanding the different types of accounts in Ethereum is crucial to navigating the blockchain ecosystem effectively. While there are only two types of accounts, how they are controlled and operated on the network can be quite different.
The first type of account is the externally owned account (EOA). EOAs are user accounts that consist of private and public key pairs.
These accounts can hold an ether balance and send and receive transactions. An Ethereum account is controlled by a private key that corresponds to its public key, which is hashed to determine the account address.
This means that an account can send transactions from its private key and trigger smart contract functionality.
The other type of account is the contract account. Unlike EOAs, which are controlled by a private key, contract accounts are controlled by code.
Contract accounts can also hold a balance of ether or ERC-20 tokens, but the coins held at the account’s address cannot be spent by an external owner because there is no private key.
Code execution is triggered by transactions or messages received from other contracts, and contract accounts can perform operations of arbitrary complexity.
This means that their state is not always the same and can change when the account is called upon.
By understanding the differences between these two account types, you can easily navigate Ethereum and begin to deploy smart contracts and trigger smart contract functionality.
Both forms of Ethereum accounts share the same four features: a nonce, balance, codeHash, and storageRoot:
Nonce: For accounts that are owned by third parties, this figure indicates how many transactions were sent from the account's mailing address. The nonce for a contract account is the total number of contracts the account has produced.
Balance: There are a certain number of Wei (a unit of ETH denomination) owned by this Ethereum address, with 1e+18 Wei (exponential notation) per ETH. 1 ETH is equal to 1x1018 Wei, or 1e+18 Wei.
codeHash: The code for an account on the Ethereum Virtual Machine is represented by this hash (EVM). The component of the protocol that actually handles transaction processing is Ethereum's own virtual machine or EVM. The hash of the empty text is stored in the codeHash field for EOAs. The code is hashed and saved as the codeHash for contract accounts.
storageRoot: This hash represents the root node of a Merkle Patricia tree (a tree of hashes). The hash of the storage contents of the ETH account is encoded in this tree, which is empty by default.
How To Set Up An Ethereum Wallet On Nano Ledger
To get started, ensure that your Ledger device is set up and updated with the latest firmware and that your computer has Google Chrome or Firefox installed.
Open My Ledger in Ledger Live,
Connect and unlock your Ledger device,
Allow My Ledger to access your device.
Next, find Ethereum in the app catalog, click the Install button, and confirm the installation on your Ledger device.
Enable blind signing for an added layer of security.
Connect and unlock your Ledger device, open the Ethereum app, navigate to Settings by pressing the right button, and press both buttons to validate.
Your Ledger device displays Blind Signing, and you can press both buttons again to enable transaction blind signing.
With your Ledger device set up and blind signing enabled, you can now securely manage your digital assets using MyEtherWallet.
It is important to note that MyEtherWallet does not store your private keys, so you are solely responsible for protecting your assets.
To access unsupported or missing ERC-20 tokens, you can use MyEtherWallet's "Add Custom Token" feature to create a custom token with the contract address and decimals.
Overall, using MyEtherWallet with a Ledger device provides a powerful and secure way to manage your digital assets. By following these steps, you can safely store your crypto and have peace of mind knowing that your private keys are protected.
How To Set Up Erc20 Wallet On Ethereum Wallet
The first step in setting up your Ethereum wallet is to download the MetaMask browser extension.
Simply go to the MetaMask website, click on "Download," and select "Install MetaMask for Chrome" to add the extension to your browser.
Once you have installed the extension, you can access it by clicking on the puzzle piece icon in the top right corner of your browser.
To make it even easier to access, you can pin it to your browser.
Create your Wallet
Now that you have installed MetaMask, you can create your wallet.
Simply click on the MetaMask icon in your browser, and select "Create a Wallet."
Follow the prompts to set up a password and watch the informational video on how MetaMask works.
Backup and Verify Your Secret Backup Phrase
Once you have set up your wallet, you will be presented with a Secret Backup Phrase.
This is a 12-word phrase that serves as your super-secret password, so make sure to back it up and store it in a safe place.
MetaMask will prompt you to verify your Secret Backup Phrase to ensure that you have backed it up correctly.
Make sure to follow the security tips provided by MetaMask, which include saving your backup in multiple places, never sharing your phrase with anyone, and being careful of phishing attempts.
Find your Ethereum address.
Congratulations! You have now set up your Ethereum wallet.
The last step is to find your Ethereum address, which you can access by opening your wallet and clicking on the letters and numbers that start with "0x...." You can also view your account details or click "View on Etherscan."
Now that you have set up your Ethereum wallet, you can use it to store, send, and receive Ethereum and other ERC-20 tokens.
How To Set Up A Multisig Wallet Ethereum
A multisig, or multi-signature wallet, is a unique digital signature requiring two or more users to sign a document or transaction as a group.
This technology offers an additional layer of security, making it more difficult for hackers to steal funds.
The concept of multisig technology is not new, but it has been around since the creation of Bitcoin. In 2012, the technology was first applied to Bitcoin addresses, which paved the way for developing multisig wallets a year later.
While there are different use cases for multisig addresses, they are primarily used for security purposes in the world of crypto.
So, how does a multi-sig wallet work?
Think of it as a secure deposit box with two locks and two keys. One key is held by Alex, and the other is held by Anne. To open the box, both keys must be used simultaneously, ensuring that neither party can access the contents without the consent of the other.
Using a multi-sig wallet adds an extra layer of security to your funds, as the funds can only be accessed by using two or more signatures. However, it's important to understand the basics of a standard Bitcoin address, which relies on a single key, before delving further into multisig wallets.
The big question is: How can you set up a multisig wallet in Ethereum?
If you're using a Metamask wallet, converting it into a multisig wallet is impossible. But you can use it to access a multisig wallet created elsewhere. There are two ways to create a multisig wallet:
Without a smart contract: This requires using an ECDSA threshold signature or multi-party signature, which can be quite complex for most users.
With a smart contract: This involves copying from an open-source Solidity repository, such as the one found on Gnosis Safe. However, there is a risk of wrongly deploying and using the smart contract, which can result in the loss of funds.
The recommended and simplest way to create a multisig wallet in Ethereum is to use Gnosis Safe.
How to set up a Multisig Wallet Ethereum with Gnosis Safe
To get started, visit the Gnosis-safe website and click on "Open App" to launch the main landing page.
To create a Gnosis Safe, you need to connect a supported wallet. Here, we will use MetaMask, but you can also use other wallets.
Once you've connected your wallet, you need to choose a chain to deploy your wallet.
Here, we will use the Goerli Ethereum testnet.
Now that you've connected your wallet and chosen a chain, click on the green button labeled "Create new Safe." You will be prompted to give your Safe a name, add owners, and set the number of confirmations required for any transaction to be approved.
Once you have filled in the required fields, click "Create" and approve the transaction.
This will deploy a smart contract and create your Safe.
After you've created your Safe, you can verify that it exists as a smart contract on the Goerli chain. Head over to Goerliscan, paste your Safe's address and check the Contract section.
You should be able to see the verified contract source code, ABI, and even the bytecode.
Since the newly created Safe has no funds, you can add some by transferring funds from another wallet of yours. Simply go to the Assets -> Coins tab and add the funds.
That's it! You have successfully created a Gnosis Safe Multisig wallet on the Goerli Ethereum testnet.
