Dencun Upgrade Leads to Dramatic Drop in Transaction Fees for Ethereum's Layer-2s

Following the successful upgrade in March 13, there has been a remarkable reduction in transaction costs on layer-2 chains, with major networks implementing blobs experiencing significant drops in average fees. For instance, on platforms like Optimism and Starknet, median gas fees have plummeted by several folds, making transactions significantly more affordable for users. This development proves the effectiveness of the Dencun upgrade in enhancing the efficiency and cost-effectiveness of Ethereum's ecosystem, and paves the way for broader adoption and scalability. However, as the number of rollups utilizing blobs increases, competition for blob space may intensify, potentially leading to slightly higher transaction costs in the future.
