Ethereum Foundation Announces New Leadership as Fusaka Upgrade and Scaling Plans Take Shape

Key Takeaways

• The Ethereum Foundation has appointed two new Co-Executive Directors: Tomasz Stańczak and Hsiao-Wei Wang.
• The leadership shift aims to sharpen Ethereum’s focus on scaling, usability, and coordination across the L1 and L2 ecosystem.
• The announcement comes ahead of the upcoming Fusaka hard fork, slated for late 2025.

The Ethereum Foundation (EF) has named new executive directors and unveiled a refreshed leadership structure, months after co-founder Vitalik Buterin publicly called for a more inclusive and scalable governance model.

This announcement comes just as Ethereum prepares for its next big upgrade, the Fusaka hard fork, which is set for late 2025. Together, the leadership revamp and the technical roadmap signal a new chapter in Ethereum’s development.

Ethereum’s New Leadership Team

On April 28, EF appointed Tomasz Stańczak and Hsiao-Wei Wang as Co-Executive Directors.

Under their guidance, EF says it will focus on scaling Layer-1 and Layer-2 networks, improving the user experience, and strengthening the app layer and ecosystem coordination.

The leadership team now includes:

• Hsiao-Wei Wang, Co-Executive Director, will bridge the board, executives, and management.
• Tomasz Stańczak, Co-Executive Director.
• Bastian Aue, responsible for organizational strategy, hiring, and training.
• Josh Stark, focused on project execution, communications, and marketing.
• Vitalik Buterin, Founder, will continue providing technical guidance.
• Aya Miyaguchi, President, works on setting the vision and managing external relationships.
• Patrick Storchenegger, Swiss counsel, handles legal and compliance matters.

EF emphasized that this new leadership model, with dual Executive Directors, brings diverse perspectives to tackle the complex challenges ahead.

The team is now set to take on Ethereum’s next phase, focusing on operational execution and board-level oversight.

Fusaka Hard Fork

The Ethereum Fusaka upgrade is expected to land sometime in Q3 or Q4 of 2025. While there’s no firm date yet, core developers remain confident the rollout will happen before year’s end.

The upgrade was originally set to include the EVM Object Format (EOF), a significant change aimed at optimizing how smart contracts run on Ethereum.

However, due to technical uncertainty and concerns about complexity, EOF has been pulled from the current scope.

With EOF out, Fusaka will focus more narrowly on scaling improvements and standardizing Ethereum’s bytecode structure.

Developers say the decision reflects a shift toward stability and performance over high-risk upgrades.

The goal is to introduce meaningful technical changes that improve how the network handles transactions, without overhauling the EVM itself.
