Sei Labs wants to simplify its blockchain by going all-in on EVM and dropping support for Cosmos transactions and smart contracts. Sei Labs, a core development team behind the S e i blockchain, has unveiled a new proposal to ditch Cosmos transactions and CosmWasm contracts and go all-in on EVM to make the blockchain simpler and easier to build on. The proposal , Sei Improvement Proposal-3, is the second to be submitted under the new SIP governance process. If passed, it would mean Sei becomes an EVM-only chain, moving away from its current dual support for both EVM and Cosmos accounts. “As EVM usage continues to dominate activity on Sei, this proposal reflects a clear path forward: a streamlined, EVM-first architecture designed to scale the next generation of DeFi, gaming, and real-world applications.” Jay Jog, co-founder of Sei Labs According to the proposal, only EVM addresses will be able to send transactions on Sei. CosmWasm contracts and Cosmos message handling would be removed, while staking and governance features will remain available through EVM precompiles.

Sei Labs said the current dual setup has created friction for users and developers, with users having to manage and link “both EVM and native addresses.” If the proposal goes through, infrastructure providers will need to switch to EVM-only APIs. Users will also need to move assets to EVM-native wallets or bridge out Cosmos assets, and CosmWasm developers will have to port their apps to EVM, the team noted. According to Sei Labs, shifting to an EVM-only setup will “significantly simplify the Sei developer and user experience, reduce infrastructure overhead, and position Sei more strongly within the broader EVM ecosystem.” Still, there’s no clear timeline for when the proposal might take effect. Amid the announcement, SEI ( SEI ) price jumped 6% to $0.2, while trading volume surged 17.27%, according to data from crypto price aggregator platforms.
