Sei Labs fully commits to Ethereum by making a daring switch to EVM-only, discontinuing support for Cosmos.

Sei Labs, the team responsible for developing the Sei blockchain, has put forward a significant change to the network’s architectural design, proposing to discontinue support for both Cosmos transactions and CosmWasm contracts.

The proposal entails a complete shift to an Ethereum Virtual Machine (EVM)-compatible structure, with the intention of streamlining the blockchain and enhancing the experience for developers.

Jay Jog, co-founder of Sei Labs, noted that the majority of current network activity revolves around EVM functionality. He stated that the initiative, referred to as SIP-3, is a strategic decision to align Sei’s direction with the trends within its ecosystem.

In this context, Jog characterized the transition as crucial for the development of Sei Giga, a high-performance blockchain aimed at scalability and user-friendliness. He mentioned that concentrating Sei’s efforts on a single virtual machine would lead to improved throughput and eliminate unnecessary complexity in its architecture.

Following the announcement of this proposal, the SEI token surged by 7%, reaching $0.20, indicating favorable market reactions toward the impending upgrade.

SIP-3 aims to transform Sei into an EVM-exclusive blockchain, gradually removing all features associated with Cosmos. This transition is expected to enhance the transaction framework and unify smart contract development under a consistent standard.

Sei Labs asserts that this progressive step is intended to minimize operational burdens and create a more unified development landscape.

The team anticipates that this change will facilitate better integration with the broader Ethereum environment and draw in additional developers looking for efficiency and ease of use.

However, this restructuring will necessitate changes from both infrastructure providers and developers.

Current wallets, decentralized applications (dApps), and services on the blockchain will need to adapt to EVM-compatible standards, while applications created on CosmWasm will require redeployment.

Moreover, asset holders using Cosmos-native tools might need to migrate their holdings or find alternative options.

The team clarified:

“Sei addresses may still be used internally by the protocol (e.g., validator addresses), and core functionalities like staking and governance will continue to be offered through precompiles.”
