Arbitrum is a leading Layer-2 scaling solution designed to enhance the Ethereum network's capabilities. By improving transaction speeds, reducing fees, and increasing scalability, Arbitrum allows users to enjoy the security of Ethereum with significantly better performance. This guide covers everything from the basics of Arbitrum and its native ARB token to practical steps for buying, storing, and using ARB.
What Is Arbitrum and How Does It Work?
Arbitrum is a Layer-2 blockchain built on Ethereum, intended to address its limitations in speed and cost. It enables all Ethereum functionalities—like deploying smart contracts and using dApps—but with greater efficiency. The key innovation behind Arbitrum is its Optimistic Rollup technology, which bundles multiple off-chain transactions into a single on-chain transaction. This process drastically reduces the load on Ethereum, cutting fees and speeding up processing times.
Unlike some other scaling solutions, Arbitrum operates in a trustless and permissionless manner. All transaction data is eventually posted to Ethereum, ensuring security and allowing anyone to validate the chain. This setup supports up to 40,000 transactions per second, a thousandfold increase over Ethereum’s base layer.
Arbitrum is also fully compatible with the Ethereum Virtual Machine (EVM), meaning developers can port their dApps from Ethereum without any code changes. To facilitate operations, Arbitrum uses its own native token, ARB, instead of ETH.
Understanding the ARB Token
The ARB token was introduced in March 2023 through an airdrop to early users. It serves primarily as a governance token within the Arbitrum ecosystem. Holders can participate in decision-making via the Arbitrum DAO, influencing the network’s future development and policies.
ARB has a total supply of 10 billion tokens. The majority—56%—is controlled by the Arbitrum community, while 11.62% was distributed via airdrop. The remainder is allocated to developers, investors, ecosystem DAOs, and a treasury managed by the DAO.
As of now, ARB ranks among the top cryptocurrencies by market capitalization, reflecting its growing adoption and utility.
The Team Behind Arbitrum and Future Roadmap
Arbitrum was developed by Offchain Labs, a company founded in 2018 by Ed Felten, Harry Kalodner, and Steven Goldfeder—all accomplished computer scientists with backgrounds in academia and blockchain research.
Since its mainnet launch in 2021, Arbitrum has consistently expanded its features. Key milestones include the introduction of the Arbitrum Bridge, integrations with major DeFi protocols, and ongoing improvements to its rollup technology. The team continues to focus on providing robust tools and resources for developers building on the network.
Future updates are expected to enhance scalability further and introduce new features, solidifying Arbitrum’s position as a top Layer-2 solution.
How to Get Started with Arbitrum
To interact with Arbitrum, you need a compatible cryptocurrency wallet. These wallets allow you to store, send, receive, and manage ARB tokens and other assets on the network. They also enable access to dApps and DeFi protocols within the ecosystem.
When choosing a wallet, prioritize security features, user experience, and support for multiple blockchains. A good wallet should offer seamless integration with Arbitrum and easy recovery options.

Managing ARB Tokens: Deposits and Storage
Once you have set up a wallet, you can deposit ARB tokens from exchanges or other sources. The process typically involves generating a deposit address in your wallet, whitelisting it on the exchange (if required), and initiating the transfer.
Always double-check addresses before confirming transactions, and ensure you have enough ETH for gas fees when moving funds between chains. Transactions on Arbitrum are usually quick and cost-effective, but it’s essential to follow security best practices.
Buying and Swapping ARB Tokens
You can purchase ARB tokens directly through supported wallets using fiat currency or other cryptocurrencies. Many wallets partner with third-party providers to offer competitive rates and low minimums.
Swapping ARB for other tokens is straightforward via built-in swap features. These tools provide real-time quotes and allow you to trade assets without leaving the wallet interface. Always review transaction details, including fees and slippage, before confirming.
Bridging Assets to Arbitrum
Bridging lets you move assets from Ethereum (or other chains) to Arbitrum. The official Arbitrum Bridge is a popular tool for this purpose. To use it, connect your wallet, select the asset and amount, and approve the transaction. The process may take a few minutes, depending on network congestion.
Bridging is essential for accessing Arbitrum’s DeFi ecosystem, as it allows you to use your existing assets on the faster, cheaper Layer-2 network.
Popular dApps on Arbitrum
Arbitrum hosts a vibrant ecosystem of dApps, including decentralized exchanges, lending platforms, and NFT marketplaces. Some of the most popular include Uniswap V3, Aave, Stargate, and Camelot. These dApps leverage Arbitrum’s scalability to offer users a smooth and cost-effective experience.
Whether you’re trading, providing liquidity, or borrowing assets, Arbitrum’s dApp ecosystem provides ample opportunities for participation.
