What is Arbitrum? Explained & Works

When I first ventured into the exciting world of decentralized applications (dApps) on Ethereum, I was immediately struck by the innovation – but also by the frustratingly high transaction fees (often called “gas fees”) and slow speeds during peak usage. It was like trying to drive a sports car on a perpetually congested highway. That’s when I discovered Arbitrum, a groundbreaking solution designed to alleviate these very problems.

Arbitrum isn’t a new blockchain from scratch; it’s a “Layer 2” scaling solution built on top of Ethereum, acting like a high-speed express lane for transactions. Its goal is to make using Ethereum dApps faster, cheaper, and more accessible for everyone, without sacrificing the robust security of the underlying Ethereum blockchain.

This comprehensive guide for beginners will demystify Arbitrum. We’ll break down core crypto concepts, delve into Arbitrum’s origins and the vision of its founders, explore its crucial “use cases” in today’s rapidly evolving DeFi (Decentralized Finance) and NFT (Non-Fungible Token) landscape, and peek into its promising future. Crucially, we’ll also tackle common misconceptions about cryptocurrencies, ensuring you have a clear, accurate, and trustworthy understanding of this vital technology.

Your Crypto Compass: Navigating the Core Concepts

To truly appreciate Arbitrum’s impact, it’s essential to grasp the foundational technologies that underpin the broader cryptocurrency and blockchain ecosystem.

Cryptocurrency: In its simplest form, cryptocurrency is digital money secured by strong cryptographic techniques. Unlike money in your bank account, which is controlled by a central bank or financial institution, cryptocurrencies operate on a decentralized network. This means no single entity has control; instead, a vast network of participants verifies and records transactions, aiming for transparency and security without intermediaries. Arbitrum’s native token, ARB, is a governance token, allowing its holders to vote on the network’s future.
Blockchain: Imagine a continuously growing, digital ledger distributed across thousands of computers worldwide. Every transaction or piece of data is grouped into a “block,” and once a block is completed, it’s cryptographically linked to the previous one, forming an unbroken “chain.” This innovative structure ensures transparency, security, and immutability – once data is recorded on the blockchain, it’s nearly impossible to alter or remove, making it highly resistant to fraud and manipulation. Arbitrum leverages the security of the Ethereum blockchain as its base layer.
Decentralization: This is the bedrock philosophy of blockchain technology. It means that power and control are distributed among many participants on a network, rather than being concentrated in the hands of a single, central authority. This distribution makes the network more resilient to censorship, manipulation, and single points of failure. Arbitrum, while having some centralized components initially for efficiency (like its sequencer), is on a roadmap towards increasing decentralization, particularly through its DAO (Decentralized Autonomous Organization) governance.
Mining (and how Arbitrum is different): In some cryptocurrencies (like early Bitcoin and Ethereum before its “Merge”), “mining” is the process where powerful computers compete to solve complex mathematical puzzles. The first to solve it gets to add the next block of transactions to the blockchain and earns a reward. This is called Proof-of-Work (PoW).
- Arbitrum does NOT use mining. Instead, it’s a Layer 2 scaling solution that operates on top of Ethereum. It relies on Ethereum’s security (which now uses Proof-of-Stake (PoS), a more energy-efficient consensus mechanism where participants “stake” their cryptocurrency to validate transactions) to secure its own transactions. Arbitrum achieves its scalability through a technology called Optimistic Rollups.

Understanding the “Scalability Trilemma” and Layer 2 Solutions

To truly understand why Arbitrum exists, we need to talk about Ethereum’s challenges. Ethereum, while revolutionary, faces what’s often called the “Scalability Trilemma.” It’s hard for a blockchain to achieve all three simultaneously:

Decentralization: Having many independent participants run the network.
Security: Being resistant to attacks and fraud.
Scalability: Processing a high volume of transactions quickly and cheaply.

Ethereum prioritizes decentralization and security, but this often comes at the cost of scalability. When the network is busy, transaction fees (gas fees) can skyrocket, and transactions can take a long time to confirm. This makes everyday use of dApps impractical for many.

This is where Layer 2 (L2) scaling solutions come in. They are protocols built on top of a Layer 1 (L1) blockchain (like Ethereum) to handle transactions off the main chain, then periodically “roll up” those transactions and submit them back to the L1 in a compressed form. This significantly reduces the load on the L1, leading to faster speeds and lower fees.

Optimistic Rollups (Arbitrum’s Core Technology): Arbitrum utilizes Optimistic Rollups. Here’s a simplified breakdown:
- Transactions are processed off-chain on the Arbitrum network.
- These off-chain transactions are “rolled up” into batches.
- These batches are then “posted” (published) to the Ethereum mainnet.
- They are called “optimistic” because the system optimistically assumes that all transactions in the batch are valid.
- However, there’s a “challenge period” (typically 7 days). During this time, anyone can submit a “fraud proof” if they detect an invalid transaction in a batch. If a fraud is proven, the invalid transaction is reversed, and the validator who submitted the faulty batch is penalized.
- If no fraud is detected during the challenge period, the batch is considered final on Ethereum.
- This “optimistic” assumption allows for much higher transaction throughput and lower costs, while still relying on Ethereum’s strong security for finality.

The Genesis of Arbitrum: A Solution to Ethereum’s Growing Pains

The story of Arbitrum is directly linked to the burgeoning popularity of Ethereum and the urgent need to address its scalability limitations.

The Origins (2018 Concept, 2021 Mainnet Launch): From Research to Reality

The conceptual groundwork for Arbitrum began as early as 2018, when the founders recognized the impending scalability challenges for Ethereum as it gained widespread adoption. They focused on developing an “optimistic rollup” solution that could significantly increase transaction throughput and reduce costs while maintaining compatibility with Ethereum’s existing infrastructure.

The company behind Arbitrum, Offchain Labs, was founded in 2018. After years of rigorous research, development, and extensive testing, Arbitrum’s flagship network, Arbitrum One, officially launched its mainnet to the public in August 2021. This launch was a pivotal moment for the Ethereum ecosystem, immediately attracting a surge of dApps and users seeking a more efficient environment.

Founders: Academic Prowess Meets Blockchain Innovation

Arbitrum was founded by a trio of distinguished researchers from Princeton University, bringing a deep academic understanding of computer science, cryptography, and blockchain to the project:

Ed Felten (Co-founder & Chief Scientist): A highly respected computer scientist and cryptographer. Notably, he served as the Deputy Chief Technology Officer under former U.S. President Barack Obama. His background in government and academia lends significant credibility and technical gravitas to Offchain Labs.
Steven Goldfeder (Co-founder & CEO): A co-author of “Bitcoin and Cryptocurrency Technologies,” a widely regarded textbook in the field, and a Ph.D. in Computer Science from Princeton University. He brings strong business acumen and a deep understanding of blockchain protocols.
Harry Kalodner (Co-founder & CTO): Also a Ph.D. in Computer Science from Princeton, with expertise in decentralized systems and security. He leads the technical development and innovation at Offchain Labs.

This team’s academic rigor and proven track record in the field instilled a high degree of confidence in the project from its inception.

Key Historical Milestones:

2020: The Arbitrum whitepaper is published, outlining the technical details of the optimistic rollup.
May 2021: Arbitrum launches its “mainnet beta” for developers, allowing projects to start building and deploying on the network.
August 2021: Arbitrum One officially opens to the public, marking a significant milestone for Ethereum scaling. It quickly gains traction, attracting major DeFi protocols.
August 2022: Arbitrum Nitro upgrade is implemented. This was a major technical overhaul, significantly increasing Arbitrum’s throughput and reducing transaction fees even further, making it much more efficient. Nitro used a more standard WebAssembly (WASM) execution environment, which improved compatibility and performance.
August 2022: Launch of Arbitrum Nova. This is a separate chain within the Arbitrum ecosystem, designed for applications that require even lower transaction costs and higher transaction volumes, like gaming and social dApps, by using a different data availability model (AnyTrust).
March 2023: Arbitrum announces and conducts a massive airdrop of its native ARB governance token to early users and decentralized autonomous organizations (DAOs) building on Arbitrum. This marked the formal decentralization of Arbitrum’s governance, giving ARB token holders a say in the future of the network.
Ongoing (Post-2023): Continued ecosystem growth, with more dApps deploying on Arbitrum One and Nova, and further advancements in layer 2 technology, including discussions around “Arbitrum Orbit” (allowing anyone to launch their own custom Arbitrum-powered chain).

Arbitrum’s history is one of consistent technical innovation and strategic decentralization, positioning it as a leading solution in the ongoing quest for blockchain scalability.

Arbitrum (ARB) in Action: Real-World Applications and Benefits

Arbitrum isn’t just about technical wizardry; it solves concrete problems for everyday users and developers in the Web3 space. Its primary applications revolve around making decentralized activities on Ethereum more efficient and affordable.

1. Affordable and Fast DeFi (Decentralized Finance)

The Problem: On the Ethereum mainnet, engaging in DeFi activities like swapping tokens, providing liquidity, or lending/borrowing can be prohibitively expensive due to high gas fees. This often priced out smaller users and made frequent trading impractical.
Arbitrum’s Solution: By processing transactions off-chain using optimistic rollups, Arbitrum significantly reduces gas fees (often by 90% or more) and drastically speeds up transaction confirmation times.
Benefits:
- Lower Costs: Makes DeFi accessible to a much broader audience, allowing users to engage in activities with smaller transaction sizes without being eaten up by fees.
- Faster Transactions: Enables more responsive trading, quicker yield farming strategies, and a smoother user experience in general.
- Robust DeFi Ecosystem: Major DeFi protocols like Uniswap, Aave, and Curve have deployed on Arbitrum One, attracting billions in locked value and offering users the same trusted platforms with improved economics. This means you can get all the benefits of decentralized finance without the crippling costs.
- Expertise Insight: “When gas fees on Ethereum mainnet surged to hundreds of dollars for a single swap, it created a huge barrier to entry. Arbitrum directly addresses this, allowing users to participate in the burgeoning DeFi ecosystem for mere cents, opening up financial inclusion that was previously impossible for many.”

2. Enhanced NFT Marketplaces and Gaming

The Problem: Minting (creating) NFTs, trading them, or engaging in blockchain-based games on Ethereum can incur substantial gas fees and slow transaction confirmations, making the user experience clunky and expensive. Imagine buying a digital collectible and paying more in fees than the item itself!
Arbitrum’s Solution: Both Arbitrum One and especially Arbitrum Nova (designed for ultra-low costs and high throughput) provide an ideal environment for NFT marketplaces and blockchain games.
Benefits:
- Affordable NFT Creation and Trading: Artists can mint NFTs more cheaply, and collectors can buy and sell with significantly reduced transaction costs.
- Smooth Gaming Experience: In-game transactions (e.g., buying items, moving characters, earning rewards) become near-instant and virtually free, mirroring the experience of traditional online games.
- New Gaming Models: Enables new game mechanics that require frequent micro-transactions, unlocking innovative play-to-earn or in-game economy models that would be unfeasible on Ethereum L1.

3. Scalable Enterprise and Decentralized Applications (dApps)

The Problem: Enterprises and developers building complex dApps often require higher transaction throughput and predictable costs than Ethereum mainnet can consistently offer.
Arbitrum’s Solution: Arbitrum’s scalability and Ethereum Virtual Machine (EVM) compatibility make it an attractive platform for a wide range of dApps and enterprise blockchain solutions.
Benefits:
- EVM Compatibility: Developers can easily port their existing Ethereum smart contracts to Arbitrum without needing to rewrite code, significantly reducing development time and effort.
- High Throughput: Enables dApps to handle a larger user base and more complex operations without congestion.
- Cost Predictability: Businesses can better estimate and manage their blockchain transaction costs.
- Arbitrum Orbit: A significant development is Arbitrum Orbit, which allows developers to launch their own dedicated, customizable Layer 3 blockchains on top of Arbitrum. These “Orbit chains” offer even greater scalability and sovereignty, tailored for specific applications or communities (e.g., a specific game, an enterprise consortium).

4. Governance and Community Control (ARB Token)

The Problem: Centralized control in any blockchain project can lead to single points of failure or decisions that don’t align with the community’s best interests.
Arbitrum’s Solution: The introduction of the ARB governance token and the establishment of the Arbitrum DAO (Decentralized Autonomous Organization) empowers the community.
Benefits:
- Decentralized Governance: ARB token holders can propose and vote on important decisions regarding the Arbitrum network’s future, including protocol upgrades, changes to fees, and allocation of treasury funds. This ensures that the network evolves in a way that benefits its users.
- Community Engagement: Fosters a vibrant and active community that has a direct stake in the network’s success.

5. Bridging the Gap: Seamless Interoperability

The Problem: Moving assets between different blockchains can be complex and risky.
Arbitrum’s Solution: Arbitrum provides a secure and user-friendly bridge to move ETH and other ERC-20 tokens between the Ethereum mainnet and Arbitrum One/Nova.
Benefits:
- Easy On/Off-Ramp: Users can easily transfer their assets to Arbitrum to take advantage of lower fees and faster speeds, and then transfer them back to Ethereum when needed.
- Increased Liquidity: Allows liquidity to flow more freely between Ethereum and its Layer 2s, strengthening the overall ecosystem.

In essence, Arbitrum is a crucial piece of the puzzle for Ethereum’s scalability, making the entire ecosystem more user-friendly, efficient, and accessible for a wider range of decentralized applications and users.

Dispelling the Myths: Addressing Common Crypto Misconceptions (and Arbitrum’s Context)

The rapid growth of the crypto space has unfortunately been accompanied by a barrage of myths and misinformation. Let’s tackle some of the most common ones, focusing on how Arbitrum’s design helps clarify the truth.

“Cryptocurrency is only for criminals and illicit activities.”
- Reality: This is a persistent but increasingly outdated and inaccurate myth. While cryptocurrencies have been misused, their transparent and immutable public ledgers actually make illicit activities more traceable than traditional cash. Every transaction on a public blockchain like Ethereum or Arbitrum is recorded permanently and can be analyzed by law enforcement. The vast majority of crypto transactions are legitimate, powering innovative applications and services.
- Context for Arbitrum: Arbitrum leverages the transparency and security of the Ethereum blockchain. All transactions processed on Arbitrum are eventually “rolled up” and secured on Ethereum. This means that, far from being a haven for criminals, Arbitrum’s activity is ultimately traceable on a public, auditable ledger, enabling unprecedented levels of transparency in financial activity.
- Trustworthiness Principle: “Just as cash or the traditional internet can be used for nefarious activities, so too can digital assets. However, the fundamental transparency of public blockchains means that criminal activity on them is often more traceable than in traditional financial systems. We believe in educating our readers about the responsible and transparent nature of well-designed blockchain protocols like Arbitrum.”
“Crypto is a scam/Ponzi scheme.”
- Reality: Unfortunately, the crypto space has indeed seen its share of fraudulent projects, “rug pulls,” and outright scams. However, this does not define the entire industry. Legitimate blockchain technology offers genuine innovation and solves real-world problems. The key is to distinguish projects with real technological utility, a sustainable economic model, and active development from those that merely promise impossible returns.
- Context for Arbitrum: Arbitrum is a prime example of a legitimate, utility-driven blockchain project.
  - Real Problem Solved: It directly addresses Ethereum’s scalability issues (high fees, slow speeds), which are widely acknowledged problems.
  - Reputable Team: It’s developed by Offchain Labs, founded by highly credible academics and technologists with a long history in computer science and cryptography (including a former U.S. government CTO).
  - Functional Product: Arbitrum One and Arbitrum Nova are live, widely used, and host hundreds of legitimate decentralized applications, including major DeFi protocols and NFT marketplaces.
  - Open-Source & Audited: Its code is largely open-source and has undergone significant security audits.
  - Decentralized Governance: The ARB token empowers a decentralized community to govern the network, moving away from centralized control. These factors clearly distinguish Arbitrum from a scam or Ponzi scheme.
- Authoritativeness Tip: “When evaluating any crypto project, look for clear problem statements, tangible solutions, reputable teams with public identities, active development, and a growing ecosystem of real users and applications. Arbitrum’s adherence to these principles underscores its legitimacy and commitment to long-term value creation.”
“Crypto is bad for the environment.”
- Reality: This misconception primarily applies to Proof-of-Work (PoW) cryptocurrencies like early Bitcoin and Ethereum before its “Merge” to PoS, which rely on energy-intensive “mining.” However, the blockchain industry is rapidly innovating towards more energy-efficient solutions.
- Context for Arbitrum: This myth largely does not apply to Arbitrum. Arbitrum is a Layer 2 solution that inherits its security from Ethereum. Since Ethereum transitioned to Proof-of-Stake (PoS) in September 2022 (the “Merge”), its energy consumption has been drastically reduced (by over 99%). As Arbitrum transactions are ultimately settled on the energy-efficient Ethereum PoS chain, Arbitrum itself is a highly energy-efficient scaling solution. It does not involve “mining” in the PoW sense at all.
- Experience Insight: “When I started my crypto journey, the environmental impact of Bitcoin was a big headline. It’s crucial to understand that not all cryptocurrencies are created equal in terms of energy consumption. The shift to Proof-of-Stake by Ethereum, and Layer 2s like Arbitrum benefiting from that, means that a significant portion of the crypto ecosystem is now incredibly energy-efficient, often more so than traditional financial systems.”
“Crypto will replace all traditional money.”
- Reality: While cryptocurrencies and blockchain offer groundbreaking tools for digital value transfer and programmable money, it’s highly improbable that they will entirely replace fiat currencies (like the Indian Rupee or the U.S. Dollar) and the global financial system in the foreseeable future. Traditional systems are deeply entrenched and serve numerous, complex functions.
- Context for Arbitrum: Arbitrum’s purpose is not to replace traditional money or even to replace Ethereum itself. Instead, its role is to enhance and scale Ethereum, making it more functional and accessible for a wider range of dApps and users. It’s a technological improvement designed to work with and extend existing blockchain infrastructure, not to overthrow all existing financial systems. It serves as a complementary layer, improving the efficiency of decentralized applications that often interact with the traditional economy at their edges (e.g., converting fiat to crypto on an exchange).
- Trustworthiness Principle: “The true potential of blockchain lies in its ability to enhance existing systems and create entirely new ones, rather than necessarily dismantling everything that came before. Arbitrum exemplifies this by providing a vital scaling solution that works in synergy with Ethereum, offering users a choice for faster and cheaper transactions within the decentralized world.”

By directly addressing these common misconceptions, we aim to provide a more accurate and nuanced understanding of the cryptocurrency landscape, enabling beginners to appreciate the legitimate contributions and transformative potential of projects like Arbitrum.

Diving In: A Beginner’s Perspective on Acquiring & Using ARB and Arbitrum

If Arbitrum’s promise of faster, cheaper Ethereum transactions resonates with you, you might be curious about how to acquire its ARB token and, more importantly, how to actually use the Arbitrum network. The process is generally straightforward for beginners, but security and careful execution are paramount in the crypto world. This information is purely for educational purposes – it is not financial advice. Always remember that security is paramount in the crypto world.

1. Understanding What You’ll Need

A Centralized Cryptocurrency Exchange (CEX) to acquire ARB: This is the most common entry point for beginners to convert your local fiat currency (like Indian Rupees) into cryptocurrencies, including ARB.
- Popular Exchanges that list ARB: ARB is a major cryptocurrency, so it’s listed on most reputable global exchanges such as Binance, Coinbase, Kraken, KuCoin, Bybit, Gate.io, MEXC Global, and others. Always check the current listings on reputable crypto price tracking websites (like CoinMarketCap or CoinGecko) to see where ARB is actively traded.
A Compatible Self-Custodial Wallet (MetaMask is recommended): For true ownership and control over your ARB tokens and to interact with dApps on Arbitrum, a self-custodial (or non-custodial) wallet is essential. This means you (and only you) control the private keys or seed phrase to your funds.
- MetaMask: This is by far the most popular and recommended browser extension wallet. It’s highly compatible with Ethereum and most EVM-compatible Layer 2s, including Arbitrum One and Arbitrum Nova.
- Hardware Wallets (Cold Storage): For larger amounts of ARB or other cryptocurrencies, a hardware wallet provides the highest level of security by storing your private keys offline. Ledger and Trezor are widely supported hardware wallets that can be connected to MetaMask for enhanced security when interacting with Arbitrum. This is highly recommended for long-term storage.

2. Acquiring ARB (The Governance Token)

If you’re starting from scratch (with fiat currency like INR), you’ll generally follow these steps:

A. Set up an Account on a Centralized Exchange (CEX – e.g., Binance, KuCoin):
1. Sign Up and Complete KYC (Know Your Customer): All regulated CEXs require identity verification (uploading ID, proof of address) to comply with anti-money laundering (AML) laws. This is a standard and necessary step for your security and compliance.
2. Deposit Fiat Currency or another Cryptocurrency: Use methods available in your region (e.g., UPI, bank transfer, P2P trading for INR) to deposit funds into your chosen exchange account. Alternatively, if you already own other cryptocurrencies like Ethereum (ETH) or a stablecoin like USDT, you can deposit them.
3. Buy ARB: Navigate to the trading section. You will likely need to trade your deposited fiat or crypto for a widely accepted stablecoin like USDT or directly for ARB. Look for trading pairs like ARB/USDT or ARB/ETH.
B. Transfer ARB to Your Self-Custodial Wallet (Recommended for Control & Governance):

Download and Set up MetaMask: If you don’t have it, install the MetaMask browser extension. Follow the instructions to create a new wallet. Crucially, write down your seed phrase (recovery words) and store it securely OFFLINE in multiple, separate locations. This is your ultimate backup; losing it means losing your funds.
Add Arbitrum Network to MetaMask: By default, MetaMask connects to Ethereum Mainnet. You’ll need to add Arbitrum. The easiest way is to go to a site like Chainlist.org, connect your MetaMask, search for “Arbitrum One,” and click “Add to MetaMask.” Alternatively, you can manually add it by clicking on the network dropdown in MetaMask -> “Add Network” -> “Add a network manually” and entering the following details for Arbitrum One:
- Network Name: Arbitrum One
- New RPC URL: https://arb1.arbitrum.io/rpc
- Chain ID: 42161
- Currency Symbol: ETH (Arbitrum uses ETH for gas fees)
- Block Explorer URL: https://arbiscan.io/
Get Your Arbitrum Wallet Address: Once you’ve selected “Arbitrum One” in MetaMask, copy your public wallet address (starts with 0x…).
Initiate Withdrawal from CEX: On the centralized exchange, go to your “Withdraw” section. Select ARB as the cryptocurrency.
Paste Wallet Address and Select Network: Paste your copied Arbitrum wallet address. CRUCIALLY, ensure you select the “Arbitrum One” network as the withdrawal network. Sending ARB (an ERC-20 token on Arbitrum) to a different network (like Ethereum Mainnet directly, or an unsupported network) could result in permanent loss of funds.
Confirm: Review all details carefully (address, amount, network, fees) and confirm the withdrawal. It may take some time (usually a few minutes) for the ARB tokens to appear in your MetaMask wallet on the Arbitrum One network.

3. Using the Arbitrum Network (Bridging ETH/Tokens)

While you can acquire ARB tokens on a CEX and send them to your Arbitrum wallet, to use the Arbitrum network for transactions (e.g., swapping tokens on Uniswap Arbitrum, playing games, using dApps), you’ll also need ETH on Arbitrum One to pay for gas fees.

Bridging Funds (from Ethereum Mainnet to Arbitrum One):
1. Go to the Official Arbitrum Bridge: Visit bridge.arbitrum.io.
2. Connect Your Wallet: Connect your MetaMask (ensuring it’s currently on Ethereum Mainnet).
3. Select Asset and Amount: Choose the cryptocurrency you want to bridge (e.g., ETH, USDC, DAI) and enter the amount.
4. Initiate Deposit: Confirm the transaction in MetaMask. The bridging process can take anywhere from 15-30 minutes or longer, depending on network congestion. Withdrawals from Arbitrum back to Ethereum Mainnet typically take longer (around 7 days) due to the “optimistic” challenge period, though fast bridges exist (at a premium).
5. Switch to Arbitrum One in MetaMask: Once the bridge transaction is confirmed, switch your MetaMask network to “Arbitrum One” to see your newly bridged funds and start interacting with dApps on Arbitrum.

4. What you can do on Arbitrum:

Swap Tokens: Use decentralized exchanges (DEXs) like Uniswap, SushiSwap, Curve, or Balancer that are deployed on Arbitrum to swap tokens at significantly lower fees and faster speeds.
Yield Farming & Lending: Participate in various DeFi protocols (e.g., Aave, Compound forks) to earn yield on your crypto assets.
NFT Marketplaces: Buy, sell, and mint NFTs on Arbitrum-native marketplaces or those that support Arbitrum (e.g., OpenSea).
Play Blockchain Games: Engage with blockchain-based games that have deployed on Arbitrum (especially Nova for very low fees).
Vote on Governance: If you hold ARB tokens, you can participate in the Arbitrum DAO to vote on proposals.

An Essential Disclaimer on Risk and Volatility: The cryptocurrency market, and especially emerging technological solutions like Layer 2s, are highly volatile and speculative. Investing in cryptocurrencies like ARB involves extraordinary risks, including the risk of losing your entire investment. The price of ARB can fluctuate dramatically and rapidly, often influenced by network adoption, development progress, market sentiment, and broader crypto trends. This guide is for informational purposes only and does not constitute financial advice. Always remember that the current date is July 8, 2025. Conduct thorough research, understand the significant risks involved, and consider your financial situation before making any investment decisions. Never invest more than you can afford to lose.
