Sei Labs, the core development team behind the Sei (SEI), has submitted a proposal, SIP-3, to transition the network to an Ethereum Virtual Machine (EVM)-only model. The proposal seeks to remove support for CosmWasm and native Cosmos transactions to focus solely on an EVM-based architecture. This shift aims to simplify Sei’s ecosystem and reduce the complexities of maintaining dual support for both EVM and Cosmos environments. Sei Labs Pushes for EVM-Only Network SIP-3 suggests that only EVM addresses can initiate transactions, and all future transactions should be EVM-exclusive
