Coinbase's L2 'Base' Shifts from OP Stack to a Proprietary Integration Stack

Coinbase-supported Ethereum Layer 2 (L2) network 'Base' revealed on the 18th its plan to gradually reduce its dependency on Optimism's development framework 'OP Stack', transitioning to a proprietary managed integration stack. Since its launch in 2023, Base has rapidly expanded its user base and now boasts one of the largest shares in the Ethereum (ETH) L2 market. According to data from DeFiLlama, as of the time of writing, the total value locked (TVL) has reached approximately $3.85 billion, equivalent to about 596 billion yen, marking it as a significant player in the L2 ecosystem.
