Tomasz, a pivotal figure in the Ethereum ecosystem, announced today his decision to step down from his role as Co-Executive Director (Co-ED) of the Ethereum Foundation (EF) at the end of February 2026. This significant leadership transition will see Bastian Aue stepping into an expanded Co-ED role, serving alongside the incumbent Hsiao-Wei. The announcement signals a planned and confident shift within the Foundation, emphasizing a bright future for builders, the Ethereum network, the EF itself, and Tomasz’s personal endeavors.
Background and Context of the Leadership Transition
Tomasz’s tenure as Co-ED has been marked by a period of strategic recalibration and accelerated operational enhancements within the Ethereum Foundation. Joining Hsiao-Wei, Tomasz brought a wealth of experience, notably as the founder of Nethermind, a prominent Ethereum client team. His appointment, which is inferred to have occurred approximately a year prior to the publication of this announcement (likely early 2025), was a bold move by the EF board, aimed at injecting new energy and direction into the organization.
The Ethereum Foundation, a non-profit organization, serves as the steward of the Ethereum protocol, supporting its development and broader ecosystem. The Co-ED role is instrumental in guiding the Foundation’s strategic initiatives, fostering innovation, and ensuring the network’s long-term health and decentralization. During his time, Tomasz championed a vision of the Co-ED position as one offering substantial impact, empowering talented individuals within the EF and across the wider Ethereum community.
Key achievements under his co-leadership include a significant acceleration of decision-making processes, a renewed focus on engaging younger generations of builders, and a more open communication strategy across social media and podcasts. The EF also became more receptive to institutions, strengthened support for founders, and established clearer treasury policies. Efforts to bolster local hubs and communities, introduce compensation policies, clarify the Layer 1 (L1) and Layer 2 (L2) relationship, and enhance internal and external transparency regarding budgets and organizational structure were also either completed or substantially improved. Tomasz noted that the EF is currently in a "healthy state," balancing long-term goals with the need for agile change, characterizing it as "unique, far from boring, very resilient, and led by highly intelligent people."
His decision to step down is not driven by dissatisfaction but by a perceived completion of his immediate objectives and a desire to return to more hands-on building. Tomasz articulated that his ability to execute independently within the EF would naturally diminish over time, and his continued presence into 2026 would feel like merely "passing the baton." This structured transition underscores the Foundation’s maturity and its capacity for leadership evolution without disruption.
Ethereum’s Strategic Horizon: A Multifaceted Future
The departing Co-ED’s reflections offer a comprehensive outlook on Ethereum’s strategic trajectory, emphasizing its growing role across various sectors. Despite the inherent volatility of cryptocurrency markets and the emergence of competing ideas, Tomasz highlighted an unwavering conviction in Ethereum’s technology, governance, and future significance.
Institutional Adoption and Financial Integration:
A central theme is Ethereum’s ascendance as the "clear institutional preference in 2025." This is supported by dashboards showing its growing market share in stablecoins and Real World Asset (RWA) activity. Stablecoins, digital currencies pegged to fiat currencies like the US dollar, represent trillions in value and are increasingly settling on Ethereum due to its robust security and established infrastructure. Similarly, RWAs – tokenized representations of tangible assets such as real estate, commodities, or intellectual property – are finding a natural home on Ethereum, leveraging its programmability and transparency. This trend is further solidified by Ethereum’s reputation as the "lowest-risk chain," attributed to its credible neutrality, decentralization, and an impressive record of no downtime since its genesis. These attributes provide institutions with an infrastructure that offers uniquely low counterparty, technology, and jurisdiction risks, making it an attractive platform for traditional finance. The upcoming major institutional Ethereum conference in New York City this year is a testament to this deepening integration.
The Rise of AI and Agentic Systems:
Beyond traditional finance, Tomasz envisions Ethereum as the foundational layer for an emerging "agentic economy" driven by artificial intelligence. He foresees a near future where robots, new forms of governance, and AI-powered healthcare and education systems interact seamlessly, with Ethereum serving as the "natural infrastructure layer for coordination of all these technologies." The rapid advancements in open-source Large Language Models (LLMs) and the increasing excitement around open-source agentic workers are seen as parallels to the early innovation witnessed in Ethereum. While acknowledging the privacy and security challenges posed by these new paradigms, the cypherpunk ethos of Ethereum is expected to remain intact, with dedicated builders and security experts ensuring privacy preservation and access to essential infrastructure. The EF itself has a dedicated Decentralized AI team actively delivering standards, experiments, and solutions for this agentic economy.
Upholding Cypherpunk Ethos Amidst Growth:
Despite the growing openness to institutional engagement and new applications, the Ethereum Foundation remains firmly rooted in its cypherpunk values. Initiatives like Vitalik Buterin’s Silviculture Society actively advise senior leaders on emerging risks and caution against deviations from core principles. Buterin’s series of tweets at the beginning of 2026 further emphasized the fundamental importance of these values to the EF’s existence. Projects like PSE and Kohaku are now intensely focused on "applied privacy," demonstrating a practical commitment to protecting user data. Furthermore, the Protocol team has increased its efforts in security and censorship resistance through programs like FOCIL and the "Trillion Dollar Security program," reinforcing Ethereum’s foundational integrity.
Scaling and the Layer 2 Ecosystem:
The relationship between Ethereum’s Layer 1 and its burgeoning Layer 2 ecosystem has been a critical discussion point. Tomasz highlighted Vitalik Buterin’s recent posts as providing much-needed clarity on how L2s extend or build upon Ethereum, offering various security and decentralization trade-offs. L2s differentiate themselves by optimizing for scaling, decentralization, historical state availability, and privacy, among other parameters. The EF’s Platform team has actively engaged over 20 Ethereum L2s at events like the "Network School" to discuss the future of scaling, differentiation, and interoperability. This focused approach has led to clearer visions for teams building base rollups, native rollups, and synchronous composability. A notable trend observed is that major Ethereum rollups are increasingly "overtaking all AltL1s in the stablecoin and TPS metrics," a trajectory Tomasz is convinced will continue.
Future Protocol Developments:
Looking ahead, the EF plans to release a proposal for a merged "LEAN Ethereum" and core development roadmap, providing clear guidance and coordination for 2026 and beyond. This follows two successful network upgrades in 2025, demonstrating the core developers’ capability to deliver essential improvements on schedule. Furthermore, the EF maintains a robust "quantum strategy," with top researchers finalizing specifications and engineers working on implementations to ensure post-quantum security, a critical consideration for the long-term viability of cryptographic systems.
The Ethereum Foundation’s Evolving Role and Leadership
The EF itself has undergone significant internal transformations under Tomasz’s co-leadership. The organization has focused on building a resilient and dynamic structure capable of adapting to the rapid pace of technological evolution. The Ecosystem Development (EcoDev) team, led by James Smith, is specifically tasked with fostering the success of founders, institutions, and governments building on Ethereum. This is complemented by a dedicated Global Policy Support team, with Bastian Aue and Tju Liang providing strong leadership in this area. The Foundation is also leveraging AI for internal coordination, streamlining efforts and improving efficiency. Communication about roadmaps, use cases, and applications has been significantly clarified through the excellent work of teams behind ethereum.org and forkcast.org.
The continuity and strength of the EF’s leadership are central to this transition. Hsiao-Wei will continue her impactful role as Co-ED, providing stability and institutional knowledge. Bastian Aue, whose leadership in policy support and long-term strategy has been invaluable, will step into an expanded Co-ED capacity alongside Hsiao-Wei. Tomasz expressed immense confidence in their ability to lead, noting they "will have the support of the best talent in crypto." Other key figures include Josh Stark, recognized for his exceptional talent in executing operational changes swiftly and leading major communication shifts on social media in 2025. The engineers and researchers within the Protocol cluster are working more closely than ever, confidently setting roadmaps and tackling the most challenging technological hurdles.
The EF’s commitment to global community building remains strong. The "Ethereum Everywhere" initiative actively supports hubs in San Francisco, Lagos, London, Berlin, and Hong Kong. The Academic Secretariat team is planning numerous university events for the year, and the "pop-up cities" concept continues to gain momentum, fostering connections among new builders and long-term thought leaders worldwide. Looking ahead, Devcon Mumbai in 2026 is anticipated to be a landmark event, bringing global blockchain thought leaders and founders to India, a community Tomasz believes has long deserved such a platform. The EF is also enhancing its outreach to the new generation of builders, leveraging new voices and the excitement surrounding agentic AI to position Ethereum as its go-to trust infrastructure. Furthermore, the newly formed DeFi coordination team at the EF is set to publish its plans and roadmap, signaling a renewed focus on supporting this critical segment of the ecosystem.
Tomasz’s Next Chapter: A Return to Hands-On Building
As Tomasz prepares for his departure, he outlined his future plans, signaling a return to a more direct, hands-on role in the ecosystem. He intends to act more as a core developer and product builder, with a particular focus on "agentic core development and agentic governance." This pivot reflects a profound conviction in the transformative potential of agentic systems and AI-assisted discovery, akin to his foundational belief in Ethereum’s capacity to reshape financial systems when he launched Nethermind in 2017. He acknowledges the "impermanence or even uselessness of some of the agentic ideas" but champions the "playful experimentation that defined much of the early Ethereum innovation."
Tomasz plans to continue traveling and collaborating with local communities, assisting businesses in building on Ethereum. Crucially, he will remain available for support, connecting individuals with the EF and offering advice on Ethereum’s vision and strategy. His DMs will stay open, and he pledges to "always put pressure on the Ethereum ecosystem to move at pace," indicating his continued dedication to its progress. His desire to work directly with founders in frontier tech and Ethereum underscores his commitment to seeing his long-articulated vision come to fruition.
Statements and Outlook
The leadership transition at the Ethereum Foundation is presented as a testament to the organization’s robust health and the depth of talent within its ranks. Tomasz’s announcement, while marking a significant change, is framed within a narrative of continuity and strategic advancement. The positive remarks about Hsiao-Wei’s continued leadership and Bastian Aue’s expanded role, coupled with the detailed outline of the EF’s achievements and future plans, suggest a well-managed succession designed to maintain momentum.
Industry observers are likely to view this transition as a sign of the Ethereum Foundation’s organizational maturity. The detailed roadmap for 2026, encompassing advancements in institutional integration, AI, quantum security, and L2 scaling, reinforces confidence in Ethereum’s long-term viability and its foundational role in the evolving digital economy.
