Arbitrum (ARB) has officially been listed on OKX, marking a significant milestone for both the Layer 2 scaling solution and one of the world’s leading cryptocurrency exchanges. Starting March 23, 2023, users can trade ARB in both spot and perpetual markets, with USDT-margined perpetual swaps going live just 40 minutes after the initial listing. This integration strengthens OKX’s position as a premier gateway to high-potential web3 projects while offering traders immediate access to one of Ethereum’s most promising scaling technologies.
What Is Arbitrum?
Arbitrum is a Layer 2 scaling platform built to enhance Ethereum’s performance by processing transactions off-chain and submitting compressed data back to the mainnet. Using optimistic rollup technology, Arbitrum bundles hundreds of transactions into a single on-chain proof, drastically reducing gas fees and increasing throughput. While Ethereum handles approximately 20–40 transactions per second (TPS), Arbitrum can support up to 40,000 TPS, making it an ideal environment for decentralized applications (dApps), DeFi protocols, and NFT platforms seeking speed and cost-efficiency.
This technological leap not only improves user experience but also opens doors for broader blockchain adoption across industries. With growing interest in scalable, secure, and interoperable networks, Arbitrum has emerged as a top contender in the race for Ethereum dominance beyond the base layer.
