Coinbase's Ethereum layer-2 blockchain, Base, has experienced significant growth, surpassing $4 billion in total value locked (TVL) and outperforming Ethereum and Arbitrum in daily transaction volume, partly due to memecoin mania. This surge in activity and value, which saw a 13.2% increase in TVL over the past week, is attributed to the increasing adoption of layer-2 solutions for their efficiency and lower transaction costs. Base's daily transaction count has risen from 500,000 to 3.1 million over the past 30 days, with the average transaction fee dropping from $1 to $0.2. Additionally, Base has achieved a new milestone in transactions per second, reaching 36 compared to Ethereum's 14. This growth is seen as a testament to the scalability and potential of layer-2 networks on Ethereum, with Base leading the charge.
