Sei Abandons Cosmos for EVM, TVL Triples

Sei, a high-ranking blockchain known for its parallel transaction handling design, has announced a strategic shift to focus exclusively on the Ethereum Virtual Machine (EVM) model. This decision, revealed in a post on May 7, aims to enhance the developer experience and simplify the blockchain's infrastructure. Sei has supported both Cosmos and EVM users since 2024, enabling interoperability between applications and protocols across these two systems. However, the current dual-support model has led to an infrastructure burden and a complex codebase, according to Philip Su, the engineering lead at Sei Labs. The team argues that EVM usage is significantly higher than Cosmos usage. At its peak in December 2024, there were 162 times more EVM users than Cosmos users. In April 2025, the number of Sei EVM users was 2.5 times that of Cosmos users. This disparity has influenced Sei's decision to streamline its operations by focusing solely on EVM.

The community's reaction to this proposal has been mixed. While some users support the move, citing the low usage of Cosmos, others express concern about the migration of their Cosmos-based crypto assets. One user, Wangman, raised the issue of bridging Cosmos-based assets to EVM, questioning whether Sei would provide tools for this migration. Despite these concerns, Sei has seen a surge in investor confidence, as evidenced by the growth in total locked value (TVL). Between October 2024 and May 2025, the TVL tripled from $160 million to $480 million. Additionally, the number of new Sei users increased from 35,000 to 85,000 in the past three weeks, reflecting a 72% rally in the altcoin's price from April lows to over $0.22. Although the price gave back some gains in May, bulls have defended the $0.18-$0.20 support level, suggesting a potential extended rally to $0.25 if this level holds.
