Arbitrum has just surpassed 2.1 billion transactions since its launch, as of 2025. At the same time, the total value secured (TVS) on the network has exceeded $20 billion, continuing to maintain its position as the leading Layer 2 on Ethereum $ARB
Notably, the Arbitrum ecosystem currently has over 100 chains that are live or in development, indicating that the 'chain-of-chains' scaling model is on the right track. According to published data, the GDP of the Arbitrum ecosystem has increased by over 30%, reflecting the actual usage level and positive cash flow.
Overall, I see that Arbitrum is not only increasing in the number of transactions but is also expanding the depth of its ecosystem from DeFi, gaming to app-chain infrastructure. For those following L2, this is a milestone that shows the race to expand Ethereum is still very hot and Arbitrum remains the leading name.
