Arbitrum's leadership in the Ethereum Layer 2 ecosystem is driven by its two networks, Arbitrum One and Arbitrum Nova. These networks enhance Ethereum's scalability and reduce transaction fees. Arbitrum One, launched in August 2021, utilizes optimistic rollup technology, while Arbitrum Nova, launched in August 2022, focuses on speed and cost-efficiency. The development of Arbitrum was led by Offchain Labs, a company with a strong background in blockchain research.

Data insights from Arbitrum One show significant growth in Total Value Locked (TVL), transactions, and active addresses. The average transaction fee on Arbitrum One experienced a dramatic reduction following Ethereum's Dencun Upgrade. The native token of Arbitrum, $ARB, has seen fluctuations in price and trading volume but has shown a notable increase in market cap.
