Layer two analytics platform L2beat is reporting that Arbitrum is still the industry leader in terms of total value locked which is just over $3 billion giving it a market share of 54.9%.
Optimism has an 8% L2 market share with a total value locked of $444 million, and address activity has fallen by 17.9% over the past week according to Nansen.
However, it should be noted that this is likely due to a decline in the prices of underlying assets which has been far steeper than the DeFi TVL drop.
