Arbitrum is a Layer 2 scaling solution for Ethereum that uses optimistic rollup technology to improve transaction throughput and reduce fees.
Arbitrum is a Layer 2 scaling platform built by Offchain Labs to enhance Ethereum's scalability and reduce transaction costs. It achieves this by using optimistic rollup technology, which processes transactions off-chain and posts compressed data on-chain, enabling faster and cheaper transactions while maintaining Ethereum's security guarantees. Arbitrum supports the Ethereum Virtual Machine (EVM), allowing developers to deploy existing Solidity smart contracts with minimal changes.
The Arbitrum ecosystem includes several components such as Arbitrum Nitro, the latest iteration of its rollup technology, and a comprehensive TypeScript SDK for client-side interactions. Developers can access detailed documentation, tutorials, and tools to build decentralized applications (dApps) on Arbitrum. The platform also supports launching custom Arbitrum chains via Arbitrum Orbit, enabling projects to deploy their own rollups.
What sets Arbitrum apart is its focus on compatibility and developer experience. It offers seamless integration with Ethereum tooling and wallets, extensive developer resources, and a modular architecture that supports upgrades and custom rollup deployments. Arbitrum has seen significant adoption with over 1 million users and hosts numerous DeFi protocols, DAOs, and enterprise projects. Getting started involves using the Arbitrum SDK, following developer guides, and optionally running nodes or deploying contracts using the provided tooling and documentation.
Ethereum's base layer faces scalability challenges, resulting in high gas fees and slow transaction throughput during peak demand. This limits the usability of decentralized applications and increases costs for users and developers.
