Ethereum's Fusaka upgrade, launched on December 4, 2025, has enhanced the network's speed and capacity by increasing block space and reducing node data checks. This upgrade aims to alleviate congestion from Layer-2 networks, resulting in faster transaction confirmations and lower gas fees. Following the upgrade, Ethereum's price rose to $3,215, driven by significant buying activity from mid-sized wallets holding between 1,000 and 10,000 ETH. Additionally, Santiment reported the creation of 190,000 new wallets in a single day, indicating a surge in network activity and user growth.
