Arbitrum (ARB)
Ethereum at a fraction of the cost - the leading Optimistic Rollup.
What is Arbitrum?
Arbitrum (ARB) is an Ethereum Layer 2 network developed by Offchain Labs, using Optimistic Rollup technology. It bundles hundreds of transactions together, executes them off the Ethereum mainnet, and posts a compressed summary back to Ethereum - dramatically reducing the cost per transaction while using Ethereum's security for final settlement. Transaction fees on Arbitrum are typically 10-50x cheaper than on Ethereum mainnet.
Arbitrum One is the main public network. Arbitrum Nova (using a different data availability approach) serves gaming and social applications with even lower fees. Arbitrum Orbit allows projects to deploy their own custom Layer 3 chains on top of Arbitrum, similar to Polygon supernets or Avalanche subnets.
Arbitrum Ecosystem and DeFi
Arbitrum hosts the largest DeFi ecosystem of any Ethereum Layer 2, with protocols including GMX (perpetual DEX), Uniswap v3, Aave, Curve, Camelot, and hundreds more. Total Value Locked on Arbitrum regularly exceeds $3 billion, making it one of the most significant DeFi hubs in crypto. Indian DeFi users who find Ethereum mainnet fees prohibitive often use Arbitrum for trading perpetuals and accessing yield protocols.
ARB for Indian Investors
ARB is available on Binance, Bybit, CoinDCX, and Bitget. The ARB token is a governance token for the Arbitrum DAO, which controls a large treasury of ARB tokens. ARB does not currently capture protocol fees directly, but governance discussions around fee mechanisms are ongoing. For Indian investors, ARB represents exposure to Ethereum's scaling layer and the continued migration of DeFi activity from L1 to L2.
Pros for Indian Investors
