Ethereum is undergoing Fusaka upgrade aimed to enhance the network's scalability, efficiency, and decentralization by introducing several key technical improvements. These changes primarily focus on optimizing data availability, state management, and resource usage, making Ethereum more accessible for validators, developers, and Layer 2 (L2) solutions like Arbitrum, Optimism, and zkSync.
Hard fork is scheduled to activate on December 3, 2025, at Ethereum slot 13,164,544 (approximately 21:49 UTC). This timeline is based on developer consensus and testnet progress, though minor delays could occur if issues arise during final audits.
In preparation to Fusaka upgrade we have upgraded all our Ethereum nodes powering the EVM gateways, blockingestion, and various third-party services. We do not expect any downtime during this hard fork and we will keep you informed about the progress of the maintenance.
