# Arbitrum > Powering the programmable economy Arbitrum is a suite of Ethereum scaling solutions that includes optimistic rollup and AnyTrust chains for faster, cheaper transactions. Arbitrum provides Ethereum developers Layer 2 scaling solutions including Arbitrum One optimistic rollup and Nova AnyTrust chains. Developers deploy EVM-compatible and Rust-based smart contracts via Stylus with reduced fees and faster finality. The network maintains Ethereum security guarantees while improving transaction throughput and cost efficiency through the ARB DAO governance model. - Type: Network - Sector: Blockchain Platforms - Status: Active - Founded: 2020-11-01 - Profile: https://thegrid.id/profiles/Arbitrum ## Products - [Arbitrum](https://thegrid.id/profiles/Arbitrum): Arbitrum One operates as an optimistic rollup chain that processes transactions off-chain and posts data to Ethereum L1, enabling EVM-compatible smart contracts with reduced gas costs and faster execution while maintaining Ethereum's security guarantees. (L2, Live, Main Product) - [Arbitrum Orbit](https://thegrid.id/profiles/Arbitrum): Arbitrum Orbit provides infrastructure for launching customizable L2 and L3 chains using Arbitrum Nitro technology, allowing developers to configure throughput, gas tokens, governance models and data availability layers for their specific application needs. (Node Software, Live) - [Arbitrum Bridge](https://thegrid.id/profiles/Arbitrum): Arbitrum Bridge enables bidirectional asset transfers between Ethereum and Arbitrum networks through deposit and withdrawal mechanisms. The system supports native ETH transfers and ERC-20 token bridging with configurable withdrawal periods for security. (Bridge, Live) - [Arbitrum Nova](https://thegrid.id/profiles/Arbitrum): Arbitrum Nova is an AnyTrust chain that uses a Data Availability Committee to store transaction data off-chain rather than posting it entirely to Ethereum, enabling ultra-low transaction costs. The chain settles certified batch data to Ethereum mainnet, requiring only two honest committee members for security guarantees. Nova is designed for high-frequency, cost-sensitive applications including blockchain gaming, social platforms, and NFT projects. (L2, Live) - [Arbitrum Stylus](https://thegrid.id/profiles/Arbitrum): Arbitrum Stylus is a developer tooling upgrade to Arbitrum Nitro that adds a WebAssembly (WASM) virtual machine alongside the EVM on Arbitrum One and Nova. It enables writing smart contracts in Rust, C, C++, and other WASM-compatible languages, with Stylus contracts interoperable with existing Solidity deployments through shared interfaces. WASM execution reduces gas costs for memory and compute-intensive operations compared to equivalent EVM bytecode. (Developer Tooling, Live) ## Assets - [Arbitrum (ARB)](https://thegrid.id/profiles/Arbitrum): ARB is the governance token of the Arbitrum DAO. It is used to vote on proposals that affect the operation and evolution of the Arbitrum One and Arbitrum Nova chains, including protocol upgrades, treasury fund allocation, and Security Council elections. Votes are token-weighted, and holders can delegate voting power to other addresses to enable broader participation in governance decisions.
