Arbitrum Blockchain Complete Guide: Ecosystem Projects, Layer 2 Advantages, Trading Tutorials, and Token Economics

Do you want to learn more about the applications and unique advantages of the Arbitrum blockchain? This guide will reveal how the Arbitrum Layer 2 scaling solution operates efficiently, saves transaction costs, and compare the prominent features of Arbitrum and Optimism in competition. Additionally, we will explore the projects within the Arbitrum ecosystem, how to trade on the Arbitrum network, and analyze its token economic model. Are you ready to explore the revolutionary impact of Arbitrum in this era of technological innovation in 2025? Let’s start here.

Arbitrum is an Ethereum-approved Layer 2 scaling solution that employs Optimistic Rollup technology to address Ethereum’s congestion and high fees. This technology bundles a large number of transactions and first settles them on the Arbitrum chain, then submits transaction data to the Ethereum mainnet for validation. Compared to the 10%-30% transaction fees on the Ethereum mainnet, the Arbitrum blockchain application guide clearly states that its transaction costs are significantly reduced. Arbitrum’s design includes a robust fraud-proof mechanism executed at the Ethereum layer, where validators can challenge the validity of transactions to ensure only legitimate transactions are confirmed. According to actual statistics, Arbitrum achieves a perfect balance among speed, cost-effectiveness, and compatibility with Ethereum infrastructure compared to other Optimistic Rollup solutions, making it a leader in Layer 2 scaling.

What projects are in the Arbitrum ecosystem? The ecosystem has formed a mature project matrix covering multiple fields. In DeFi, AAVE V3 on Arbitrum has a TVL of $722.59 million, and Curve Finance’s TVL is $83.39 million, providing ample liquidity for lending and trading protocols. The most representative is the perpetual contract trading platform GMX, with a TVL of $496 million, accounting for 27.53% of all DeFi protocol TVL on Arbitrum. This protocol generated $33 million in revenue over the past year. Yield aggregator projects like Jones DAO continue to attract funds and expand yields through their strategies, creating a sustainable yield flywheel. In GameFi, projects such as Treasure DAO, The Beacon, and Trident DAO have introduced innovative “Risk To Earn” economic models, stimulating player participation. Several well-known projects like Uniswap and AAVE are also deployed on Arbitrum, making it the most concentrated Layer 2 network for DeFi applications.

Arbitrum One uses a fully decentralized Optimistic Rollup technology, providing a level of security comparable to Ethereum, suitable for high-security applications like DeFi and trading. Arbitrum Nova adopts the AnyTrust protocol, where a validator committee ensures transaction validity; although security is relatively reduced, transaction costs are extremely low, making it particularly suitable for GameFi and high-frequency payment scenarios. The launch of Arbitrum Nova positions Arbitrum favorably in the gaming sector. As the ecosystem develops, this chain will truly leverage its advantages.

Practically configuring the Arbitrum Layer 2 scaling solution requires wallet setup. Users should manually add the Arbitrum network configuration in wallets like MetaMask, including RPC endpoint https://arb1.arbitrum.io/rpc, chain ID 42161, and symbol ETH. Trading on the Arbitrum network involves cross-chain asset transfer, which can be done using the official bridging tools or third-party bridges like Stargate Finance to transfer assets from the Ethereum mainnet to Arbitrum. Cross-chain transactions typically require higher fees on Ethereum for authorization and transfer; once completed, assets will appear on Arbitrum. After entering Arbitrum, users can trade on various DEXs, with trading fees reduced by over 90% compared to the mainnet. Beginners are advised to transfer a small amount first to test the process and familiarize themselves before executing large transactions.

Analysis of the Arbitrum token economic model shows that the $ARB token was officially issued on March 16, 2023, with an initial total supply of 10 billion tokens, and a maximum annual inflation of 2%, ensuring a stable supply growth. The token distribution is transparent and well-structured: Arbitrum DAO treasury holds 42.78% (4.278 billion tokens) as future development funding; user airdrops account for 11.62% (1.162 billion tokens), rewarding early participants; the ecosystem DAO receives 1.13% (113 million tokens) to support ecosystem project development. The primary use of $ARB tokens is for governance within the Arbitrum ecosystem, not for transaction fees. The Arbitrum Foundation has established an self-executing DAO governance model, allowing $ARB holders to participate directly in protocol upgrades and major decisions, embodying a commitment to fully decentralized governance. Compared to other Layer 2 projects, Arbitrum’s token economy design distributes power to the community, strengthening community self-decision-making capabilities.

The face-off between Arbitrum and Optimism showcases each’s strengths. Arbitrum performs more prominently in DeFi, with leading projects like GMX generating considerable revenue, and its ecosystem remains highly active. The Nitro upgrade enhances Arbitrum’s execution efficiency and EVM compatibility, utilizing WASM code for interactive fraud proofs. Optimism offers a more balanced deployment of various applications, but Arbitrum’s ecosystem has a stronger self-sustaining ability. User activity data shows over 1.9 million weekly active addresses on Arbitrum, indicating a stable user base. Both employ Optimistic Rollup technology for security, but Arbitrum’s superior ecosystem incentives and application design give it greater attractiveness in practical applications.

This article provides a comprehensive guide to the Arbitrum blockchain, detailing Layer 2 scaling technology, rich ecosystem projects like DeFi and GameFi, and transaction instructions. Readers can quickly learn how to configure wallets and perform cross-chain transactions, as well as understand the $ARB token economic model. Through an in-depth comparison with other Layer 2 solutions, this article offers a thorough technical analysis and ecosystem insight, suitable for professionals seeking to understand Ethereum scaling solutions and their applications.
