Arbitrum Foundation

The Arbitrum Foundation (operating at arbitrum.foundation) is a blockchain infrastructure company engineered for Ethereum scaling. Founded in 2023 and headquartered in Grand Cayman, Cayman Islands, it serves as the neutral steward of Arbitrum—a leading Layer 2 solution designed to alleviate Ethereum’s congestion and high transaction costs. Under the hood, Arbitrum employs optimistic rollups to process off-chain transactions while settling finality on Ethereum’s mainnet, enabling near-instant, low-cost smart contract execution. This allows developers and enterprises to deploy high-throughput decentralized applications (dApps) without sacrificing security or decentralization. The foundation’s role extends beyond technical development, fostering governance, ecosystem growth, and adoption within the Arbitrum network. While funding details are not publicly disclosed, its competitive positioning in the Ethereum scaling space underscores its strategic importance for Web3 innovation.
