Sei, a blockchain known for its high throughput, has proposed a significant change in its future direction. The Sei team introduced plans to discontinue support for the Cosmos ecosystem and focus exclusively on Ethereum’s Virtual Machine (EVM). This decision aims to simplify the blockchain’s infrastructure, enhance the developer experience, and allow Sei to fully leverage its parallelized transaction capabilities. While the proposal has garnered some positive feedback, it has also raised concerns, especially among users who have built on the Cosmos side of the blockchain. This move is part of Sei’s broader strategy to continue growing and expanding its user base while ensuring a more streamlined and efficient network design.

For much of its existence, Sei has supported both Cosmos and EVM-based applications, offering interoperability between the two systems. However, Sei Labs’ engineering lead, Philip Su, explained that this dual support had created an infrastructure burden and a more complex codebase. He emphasized that the majority of Sei’s user base had been using the EVM side of the blockchain, making Cosmos compatibility somewhat redundant. In fact, data from Dune Analytics showed a stark contrast in usage between the two systems. By December 2024, Sei had 324,000 users on the EVM side, compared to just 2,000 on the Cosmos side, marking a 162x difference. Even as of April 2025, the number of EVM users was still more than double that of Cosmos users. This significant disparity led Sei to reassess its resources and consider focusing entirely on EVM, which would allow the blockchain to optimize its operations and make development easier.

The move to an EVM-only model reflects a broader trend in the blockchain space, where many projects are adopting the EVM standard to take advantage of the vast Ethereum ecosystem and the support it provides for decentralized applications (dApps). Sei, with its unique parallel transaction handling design, is among the top blockchains in terms of throughput. Its decision to go EVM-only is aimed at improving scalability and transaction speed, allowing for a smoother experience for developers and users. The Sei team believes that focusing on EVM will not only make the blockchain more efficient but also better position it for future growth as the network continues to scale toward its “Giga” phase, a reference to the further expansion of its capabilities.

However, this decision has raised concerns within the Sei community. Some users who have built projects on the Cosmos side are now worried about how they will bridge their assets and migrate to the new EVM-based structure. One user, Wangman, expressed their concern, asking if Sei would build a tool to help with the migration process. These users rely on the Cosmos ecosystem for staking systems and collections, and without a clear path for transition, they are left uncertain about their projects’ future. The Sei team has yet to fully address these concerns, leaving some members of the community uncertain about their next steps.

Despite the mixed reactions, Sei has seen significant growth in terms of user base and market interest, which suggests that the move to an EVM-only future may be well-received by a broader audience. According to DeFiLlama, the total locked value (TVL) in Sei’s ecosystem has tripled from $160 million in October 2024 to $480 million in May 2025. This growth is reflected in the number of new users, which surged from 35,000 to 85,000 in just three weeks. These positive developments indicate increased investor confidence and show that Sei’s ecosystem is becoming more attractive to both developers and users.

In addition to the growing user base, Sei’s price has also seen significant movement, with a 72% rally from April lows, reaching over $0.22. Although it has pulled back slightly in May, the support levels between $0.18 and $0.20 have held strong, and there is potential for further upside. If these levels continue to hold, Sei could see a rally toward $0.25, signaling that the market remains optimistic about the blockchain’s future.

In conclusion, Sei’s decision to focus solely on EVM support and phase out Cosmos compatibility marks a pivotal shift in its strategy. While the move simplifies the blockchain’s design and aligns with the growing trend of EVM adoption, it has raised some concerns among Cosmos users who are unsure about the future of their assets. Nevertheless, Sei’s continued growth in TVL, user base, and market interest suggests that this transition could ultimately strengthen the blockchain’s position in the competitive space of high-throughput platforms. The coming months will reveal whether Sei can successfully manage this shift and keep its community intact while attracting new users and developers to its EVM-focused network.
