How to add Arbitrum Network to MetaMask? Complete guide for beginners



Brief Summary

MetaMask is a crypto wallet that is connected to the Ethereum mainnet by default. You can find the extension and mobile application on the official MetaMask website.

To connect other networks like Arbitrum, you need to add some basic blockchain information to MetaMask. This information includes the custom RPC URL, chain ID, and network name. To add an Arbitrum token, you must also import the correct token address.

Once you learn to add new blockchains to MetaMask, you can add other EVM networks such as BNB Smart Chain (formerly Binance Smart Chain) and Polygon using the same information.

Getting Started

To use the Arbitrum blockchain, you need a compatible crypto wallet like MetaMask. However, Arbitrum is not automatically added as a default blockchain in MetaMask. Setting up your wallet to connect to Arbitrum is a simple process and can be completed in no time.

Installing MetaMask

You can download MetaMask from the official website and install it on Chrome, iOS or Android. Before downloading the extension, you should make sure that you are using the official website and downloading the legitimate extension.

2. After installing the extension, you will see the MetaMask landing page. Click the [Get Started] button to get started.

3. If you are creating a new wallet, click the [Create a Wallet] button. You can also import an existing wallet with your recovery phrase using [Import wallet].

4. If you want to share your usage data anonymously with MetaMask, you can give permission to share at this stage. Whether you grant sharing permission or not does not affect your use of MetaMask.

5. Set a secure password for your wallet. This is not your recovery phrase. This password only prevents other people from accessing your wallet using your device. If you forget your password, you can access your passwords with your recovery phrase.

6. After you set a password, MetaMask will provide you with some useful information about your wallet’s recovery phrase. If you don’t know how crypto wallets serve, read this information carefully.

7. After that you will see your recovery phrase. Click the lock icon to see the sentence and jot down these words in the correct order. Keep the sentence in a safe (preferably offline) place and do not share it with anyone. These words are your ultimate backup for your wallet and its contents. Click the [Next] button to continue.

8. Now you will need to enter your recovery phrase by choosing the words in the correct order. After entering the words, click the [Confirm] button.

9. Your MetaMask wallet is now ready to use. Click the [All Done] button to view your new wallet.

10. To make MetaMask easy to access, you can pin the wallet to your Chrome browser by clicking the puzzle icon. After the initial setup, MetaMask will only depend on Ethereum. In the next step, we will explain how to connect MetaMask to Arbitrum.

Configuring the wallet

1. To add Arbitrum support to your Wallet, you need to enter some basic network information in MetaMask. First, open MetaMask and click on the network dropdown.

2. Click the [Add Network] button in the pop-up window.

3. On the [Add a network] page that will open, you will need to enter the following information. Click the [Save] button after entering the information.

Network Name (Ağ Adı)Arbitrum One
New RPC URL (Yeni RPC URL’si) 
Chain ID (Zincir Kimliği)42161
Currency Symbol (Para Birimi Sembolü)ETH
Block Explorer URL (Blok Gezgini URL’si) 

4. You can now successfully connect to the Arbitrum network.

Adding Arbitrum tokens to MetaMask

For Arbitrum tokens to be displayed in the wallet interface, these tokens must be added manually. Note that your wallet may also receive non-imported tokens, but they will not be displayed in the interface.

1. First, go to Arbiscan and find the token agreement and information of the token you want to add. If the token is not on Arbiscan, get the contract address from the project’s official website. Beware of fake contracts created by scammers.

2. Go back to MetaMask and click the [Import tokens] button.

3. Paste the contract address of the token. MetaMask will automatically fill in the rest of the information. If it is not filled in automatically, enter the information manually. Click the [Add Custom Token] button to finish.

4. Click on [Import Tokens].

5. The balance of the token you just added will now be displayed in your wallet.

Last Words

After setting up the Arbitrum mainnet in MetaMask, you can start sending crypto, collecting NFT and using DeFi DApp smart contracts. You can even trade tokens without leaving the extension. But to pay the transaction fees, you must make sure you have ETH in your wallet. You can move tokens to your wallet using an Arbitrum bridge for your ETHs on the Ethereum mainnet.

MetaMask isn’t just for Ethereum and Arbitrum. In fact, the wallet supports the entire Ethereum Virtual Machine (EVM) ecosystem, including BNB Smart Chain. With what you learned from this guide, you can now add more chains to your wallet and start using them with the right information.

+20 Satoshi Nakamoto Quotes




Motivational quote on wooden clipboard

Satoshi Nakamoto is the pseudonym used by the unknown person or group of people who created Bitcoin, the world’s first and most widely used decentralized digital currency. Despite the significant impact that Bitcoin has had on the world of finance and technology, the true identity of the person or group behind the pseudonym remains a mystery. However, the ideas and beliefs of the individual or group behind the pseudonym have been revealed through various written materials, including the Bitcoin white paper and emails sent to other members of the cryptography community. In this article, we’ll explore some of the most notable quotes attributed to Satoshi Nakamoto and discuss their significance in the context of the development and philosophy of Bitcoin.

Quotes from the Bitcoin white paper

“Bitcoin is a new electronic cash system that uses a peer-to-peer network to prevent double-spending. It’s completely decentralized, with no server or central authority.”

“The root problem with conventional currency is all the trust that’s required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.”

“The network is robust in its unstructured simplicity. Nodes work all at once with little coordination. They do not need to be identified, since messages are not routed to any particular place and only need to be delivered on a best effort basis.”

“The Bitcoin network is resistant to censorship, and cannot be shut down by any one person or organization.”

“We have proposed a system for electronic transactions without relying on trust. We started with the usual framework of coins made from digital signatures, which provides strong control of ownership, but is incomplete without a way to prevent double-spending.”

Quotes from emails to Hal Finney

“Bitcoin is very attractive to the libertarian viewpoint if we can explain it properly. I’m better with code than with words though.”

“I’ve been working on a new electronic cash system that’s fully peer-to-peer, with no trusted third party.”

Quotes from the Cryptography Mailing List

“You won’t find a solution to political problems in cryptography.”

“The root problem with conventional currency is all the trust that’s required to make it.

Despite the mystery surrounding the true identity of Satoshi Nakamoto, the quotes attributed to the pseudonym reveal a deep understanding of the challenges faced by traditional financial systems and a strong belief in the potential of cryptography and decentralized networks to create a more secure and efficient financial system. These ideas have had a significant impact on the development of modern cryptography and the emergence of cryptocurrencies like Bitcoin. While the true identity of the person or group behind the pseudonym may never be revealed, the ideas and beliefs they espoused will continue to shape the direction of the cryptocurrency and blockchain industries.

A comprehensive overview of the history and development of cryptocurrency




Cryptocurrency is a digital or virtual currency that uses cryptography for security and is decentralized, meaning it is not controlled by any government or institution. The first cryptocurrency, Bitcoin, was created in 2009 by an individual or group of individuals using the pseudonym Satoshi Nakamoto.

Bitcoin was developed in response to the 2008 financial crisis, which highlighted the need for a more secure and transparent financial system. Bitcoin is built on the blockchain, a decentralized ledger technology that allows for secure and transparent peer-to-peer transactions without the need for a third party, such as a bank.

Since the creation of Bitcoin, numerous other cryptocurrencies have been created, each with their own unique features and purposes. Some of the most well-known cryptocurrencies include Ethereum, Litecoin, and Ripple.

The use of cryptocurrency has grown in popularity over the years, with more and more individuals and businesses using it for transactions. However, its decentralized nature and lack of regulation have also raised concerns, particularly regarding its use for illegal activities.

The rise of cryptocurrency has also sparked debate among governments and financial institutions. Some have embraced the technology and are looking into ways to regulate and integrate it into the traditional financial system, while others have expressed skepticism and concerns over its potential risks.

Despite these challenges, the use of cryptocurrency continues to grow and evolve. As more people become aware of and interested in the technology, it is likely that its use and acceptance will continue to expand.

Custodial vs non-custodial NFTs: Key differences




NFTs, or non-fungible tokens, are unique digital assets that are built on blockchain technology. They are often used to represent ownership of digital assets such as artwork, collectibles, and in-game items. NFTs can be either custodial or non-custodial, and there are important differences between the two.

Custodial NFTs: Custodial NFTs are NFTs that are held by a third party, known as a custodian. The custodian is responsible for storing and managing the NFT on behalf of the owner. Custodial NFTs are often managed by centralized platforms, such as online marketplaces or exchanges.

One of the main advantages of custodial NFTs is that they are easy to use and manage. Since the custodian is responsible for storing and managing the NFT, the owner doesn’t have to worry about technical details such as private keys or wallet addresses. This can make custodial NFTs appealing to people who are new to the world of blockchain and cryptocurrency.

However, there are also some disadvantages to custodial NFTs. Since the custodian is a third party, the owner of the NFT has to trust the custodian to properly manage and secure the NFT. This can create a potential point of failure, as the custodian could potentially lose or mismanage the NFT. Additionally, custodial NFTs are subject to the policies and controls of the custodian, which can limit the owner’s control over the NFT.

Non-custodial NFTs: Non-custodial NFTs are NFTs that are managed directly by the owner, without the need for a third-party custodian. This means that the owner is responsible for storing and managing their own NFT, using their own wallet and private keys.

One of the main advantages of non-custodial NFTs is that they give the owner full control over their NFT. Since the owner is responsible for managing their own NFT, they have complete control over how it is stored and used. This can give the owner greater flexibility and freedom when it comes to using and trading their NFT.

However, non-custodial NFTs also have some disadvantages. Since the owner is responsible for managing their own NFT, they need to have a certain level of technical knowledge and expertise. This can make non-custodial NFTs less accessible to people who are new to the world of blockchain and cryptocurrency. Additionally, non-custodial NFTs are more vulnerable to loss or theft if the owner fails to properly manage their private keys.

In conclusion, custodial and non-custodial NFTs are two different types of NFTs that have their own strengths and weaknesses. Custodial NFTs are easy to use and manage, but they require the owner to trust a third-party custodian. Non-custodial NFTs give the owner full control over their NFT, but they require the owner to have a certain level of technical knowledge and expertise. The choice between custodial and non-custodial NFTs will depend on the individual needs and preferences of the owner.
