Sei [SEI] Blockchain Proposes to Drop Cosmos Compatibility and Focus on Ethereum's EVM

The Sei [SEI] blockchain has proposed dropping support for Cosmos and focusing only on Ethereum’s EVM (Ethereum Virtual Machine) model.

In an X post on the 7th of May, the blockchain said the proposal was aimed at enhancing developer experience and simplifying its design.

“This proposal aims to enhance developer experience, simplify infrastructure, and fully leverage Sei’s parallelized EVM performance as the network builds toward Giga.”

Sei is one of the high-ranking blockchains in terms of throughput, thanks to its parallel transaction handling design.

Since 2024, it has supported Cosmos and EVM users and enabled interoperability between applications and protocols across the two systems.

However, according to Philip Su, Sei Labs’ engineering lead, the current design has led to an infrastructure burden and complex codebase.

Besides, the team argued that the EVM usage was comparatively higher than Cosmos. Per Dune Analytics data, at the peak of December 2024, there were 162x (324,000 users) more EVM users than Cosmos (2000).

In April 2025, there were 2.5x more Sei EVM users than Cosmos. Overall, EMV outpaced Cosmos users.

However, the community reactions were mixed. Some supported the proposal, citing the above low Cosmos usage. But some were worried about how they would bridge their Cosmo-based crypto assets.

One user, Wangman, implored,

“Hope they build a bridge for those who have built on the OG side. Our entire collection isn’t on EVM. Would this proposal create a tool for migration? Our collection, our staking system.”

That said, Sei has seen increased investor confidence, going by the growth in TVL (total locked value).

Per DeFiLlama, the TVL has tripled from $160 million to $480 million between October 2024 and May 2025.

The altcoin’s market interest has also improved. According to Dune Analytics, new Sei users surged from 35K to 85K in the past three weeks.

This growth was reflected in the price, too, which rallied 72% from the April lows to over $0.22.

Although it gave back some gains in May, bulls defended the $0.18-$0.20 support. If the level holds, an extended rally to $0.25 could be feasible.
