Ethereum developers are preparing to introduce the network’s next upgrade, Pectra, in March 2025.

This timeline was discussed during the latest Execution Layer Meeting on Jan. 16, where key milestones leading to the mainnet activation were outlined.

According to the developers, preparation begins with finalizing block numbers for the Sepolia and Holesky forks, which is expected to conclude by Jan. 23 or 30.

Afterward, updated client versions will be released on Feb. 3. The Sepolia fork is scheduled for Feb. 12, followed by the Holesky fork on Feb. 19.

These forks will adopt shadow testing, simulating mainnet conditions to ensure realistic and efficient testing. This approach avoids creating an additional developer network, reducing complexity while thoroughly vetting the upgrade.

Christine Kim, a researcher at Galaxy Digital, acknowledged that the timeline remains flexible. She pointed out that unexpected issues during testing could cause delays, though optimism about a March activation is growing.

Kim warned on X:

“The above [date] is a tentative and optimistic timeline for pectra activation on testnets and mainnet. Bugs and issues in code found during testing may delay the timeline.”

Pectra upgrade

The Pectra upgrade has been described as Ethereum’s most ambitious hard fork and was initially split into two phases.

The first phase promises several enhancements to improve Ethereum’s efficiency and usability. Among its highlights are updates to account abstraction, validator staking processes, and deposit and exit mechanisms.

Meanwhile, Pectra’s second iteration is expected to introduce even more transformative changes. While no release date has been set for Pectra 2, it could include advancements such as Ethereum Virtual Machine (EVM) upgrades and the implementation of PeerDAS technology.

Combined, these features are designed to simplify user interactions while bolstering the network’s operational framework.
