Arbitrum is one of the most established Ethereum Layer 2 networks with genuine adoption, strong developer mindshare, and meaningful institutional traction. The network itself is high-quality: it processes roughly 40% of Ethereum L2 transaction volume, maintains $16–$20B in total value locked across its ecosystem, and supports a deep DeFi footprint with major protocols like Aave, Uniswap, GMX, and Pendle. Institutional adoption is accelerating, with Robinhood launching tokenized securities on Arbitrum One and real-world asset value exceeding $800M as of 2025.
