# Arbitrum

> Build Ethereum-connected apps and customizable blockchain networks

Arbitrum is a blockchain platform for building applications and dedicated networks connected to Ethereum. Developers can deploy Solidity smart contracts on Arbitrum One using familiar Ethereum tools, or use Stylus to write contracts in Rust, C, and C++. Its ecosystem spans financial applications, tokenization, games, and consumer services.

Teams that need their own network can launch a dedicated Arbitrum chain and configure gas tokens, data availability, governance, and validation around their requirements. Documentation provides quickstarts, SDKs, and guides for deploying contracts, operating nodes, and moving tokens through the bridge. For users exploring the ecosystem, the Arbitrum Portal brings together applications and resources for finding services built on its chains.
