Ethereum developers have officially set December 3, 2025, for the Fusaka upgrade, a pivotal enhancement in Ethereum’s roadmap, led by core protocols architects including Dankrad Feist.
The Fusaka upgrade aims to enhance Ethereum’s scalability, with expected improvements in transaction efficiency and cost reduction, potentially influencing ETH prices and Layer-2 ecosystem investments.
Ethereum developers confirm December 3, 2025, for mainnet Fusaka upgrade. Significant for Ethereum’s scalability roadmap, the upgrade aims to enhance throughput and reduce fees.
Core developers from the Ethereum Foundation, led by Dankrad Feist, are managing the upgrade. Fusaka focuses on increasing data space for rollups and boosting network performance. Feist explained, “Fusaka is the result of years of research on improving Ethereum’s capacity. By increasing data space for rollups, the network’s throughput could drastically improve—potentially leading to a significant reduction in gas fees.” – source
Fusaka Upgrade to Boost ETH Trading and Staking Yields
With Fusaka, ETH trading volumes and treasury accumulations are anticipated to rise. Similar positive impacts are expected for Layer-2 rollup tokens like ARB and OP.
Institutional interest is increasing as the upgrade may boost staking yields to 6–8%. Past Ethereum upgrades suggest potential price surges and sustained institutional engagement.
Comparison to 2022 Merge Signals Lower Fees and Throughput Boost
Fusaka is compared to the 2022 Ethereum Merge, which transitioned ETH to proof-of-stake. Like the Merge, Fusaka could lead to lower fees and enhanced throughput.
Analysts from Kanalcoin suggest that Ethereum could further institutionalize, driven by improved economics and enterprise features. Prior upgrades often led to sustained bullish trends.
