#ArbitrumDAOChains are undergoing a fix for fee oversight in the ArbOS Version 20 " #Atlas " upgrade. The transaction fee structure, consisting of L2 and L1 fees, is being revised to better align with changes in the #Ethereum network, particularly the #DencunUpgrade . The proposed adjustments involve reducing the L1 surplus fee and the L2 base fee. While these changes aim to offer users lower fees and increased transaction throughput, they will impact the revenue received by the ArbitrumDAO. A temperature check is being conducted among the #ArbitrumDAO to discuss and vote on the proposed changes. If approved, a non-emergency security council action will be initiated to implement the configuration adjustments. The timeline includes a temperature vote on Snapshot, initiation of security council action, and activation of configuration changes. Additionally, community governance calls are scheduled to discuss technical changes and gather feedback. Despite the short-term impact on revenue, the fee adjustments aim to maintain competitiveness and potentially increase transaction traffic on the Arbitrum One network.
