Ethereum Enters New Scaling Era Tomorrow With Fusaka Upgrade and PeerDAS Enhancements

• The Ethereum Foundation has issued detailed preparation steps for Layer-2’s, app developers, wallets, and infrastructure teams, ahead of the December 3 Fusaka upgrade.
• Developers must update systems ahead of new technical requirements, including testing PeerDAS, adapting to EIP-7825’s per-transaction gas cap, integrating secp256r1 passkey support, etc.

In less than 24 hours from now, the Ethereum blockchain will undergo the much-awaited Fusaka upgrade. This upgrade will bring key scalability features for users. However, the Foundation has shared some key measures that developers should take to prepare for the Fusaka upgrade.

Ethereum Foundation Asks Developers to Prepare for the Fusaka Upgrade

On December 3, the Ethereum Fuska upgrade will finally go live, thereby kickstarting the next phase of the Ethereum blockchain’s scaling roadmap. The Foundation has issued how developers need to prepare for major improvements in throughput, fees, and user experience.

For Layer-2 and rollup teams, the upgrade introduces PeerDAS, which is expected to deliver up to an 8× increase in data throughput. The Foundation urged developers to update pricing models, test PeerDAS on devnets, and prepare infrastructure for upcoming BPO forks, as mentioned in our previous story. Increased capacity will be available beginning December 9 (BPO1) and January 7 (BPO2).

Application and DeFi developers are advised to re-benchmark core processes as Fusaka enables lower transaction costs and faster, “instant-feel” confirmations. The upgrade includes CLZ opcode efficiencies, new RLP size limits, and the introduction of EIP-7825, which enforces a per-transaction gas limit cap of 2^24. The Foundation recommended verifying contract compatibility and updating transaction builders accordingly.

Wallet and user-infrastructure teams will need to support new security and signature standards enabled by the R1 curve and EIP-7951. Developers are encouraged to begin implementing secp256r1 signing flows, update passkey interfaces, and monitor adoption metrics.

Protocol-infrastructure operators are also preparing for increased gas limits, rising from 45 million to 60 million, along with new telemetry improvements under EIP-7910, as CNF reported last month. The Foundation asked teams to benchmark node performance, test history-expiry behavior, and contribute post-upgrade metrics to strengthen network reliability.

ETH Price Faces Litmus Tests At $2,800

As the Ethereum blockchain prepares for a major scalability upgrade, the ETH price faces selling pressure and is trading at the crucial support at $2,800. Popular crypto analyst Ted Pillows noted that losing $2,800 could see ETH dropping to $2,500. However, if the bulls manage to hold these levels, it could soon reclaim $3,000.

Crypto analyst Ted Pillows also reported that a large investor has opened a $56.08 million Ethereum long position using 2x leverage. The position carries a liquidation price of $1,193. Pillows noted that the trader is currently sitting on more than $400,000 in unrealized losses.
