Optimism has successfully implemented Upgrade 17 on its Layer 2 mainnet, enhancing the Superchain's security and scalability. The update introduces protocol-level data availability controls, refined fee-market mechanics, and improved fault-proof security measures. These enhancements aim to bolster congestion resistance and prepare the network for the upcoming Jovian Hard Fork and Stage 1 decentralization. The upgrade is anticipated to drive increased developer adoption and potentially add $300–600 million in total value locked (TVL) to the network. Analysts also predict continued positive price momentum for the OP token as a result of these improvements.
