Ethereum Fusaka Upgrade Launches Tomorrow: What It Means for the Network and Price

Ethereum is set to activate the Fusaka upgrade on Dec. 3, marking a significant step in the network’s ongoing improvements. The aims to make Ethereum faster, more efficient, and more secure for developers, users, and infrastructure providers alike.

According to Ethereum, for applications and Layer-2 networks like rollups, Fusaka introduces a system PeerDAS. In simple terms, it allows the network to handle more data at once, up to eight times more, without slowing down. This means cheaper fees for processing transactions and faster confirmations.

Developers using these systems need to update their software, run tests on test networks, and prepare their infrastructure for new capacity that goes live in stages on December 9 and January 7.

Additionally, Fusaka introduces a limit on how big a single transaction can be. The Fusaka hard fork introduces EIP-7825, which limits each transaction to 2²⁴ gas (≈16.8 million). This cap prevents any single transaction from consuming an entire block and enhances block efficiency.

Notably, most everyday users won’t notice a change, but developers with large batch operations must adjust their setups to stay under the new limit.

Similarly, wallet providers must adapt, as the Fusaka update, including R1 curve support and EIP-7951, enhances mobile passkey integration and signature handling.

Furthermore, protocol infrastructure teams need to benchmark performance under the higher block gas limit of 60 million, up from 45 million, and update monitoring tools to account for changes in transaction flow.

ETH is trading at $2,804, continuing its decline from November. On December 1, $39.31 million flowed out of the market, keeping the price below key moving averages.

Charts show ETH is near strong support at $2,700, with a possible drop to $2,500 if selling continues. Traders will watch these levels after the upgrade, as positive changes could help stabilize the price or spark buying.

If the upgrade is favorable, ETH could climb back to $3,063, offering short-term stability. Moving above $3,322 could show stronger buying interest, while failing to hold current levels might push it back toward $2,700.
