The Sei Network is set to undergo a significant transformation as it transitions to an EVM-only chain by mid-2026. This move follows the approval of a proposal to abandon the Cosmos ecosystem, marking a pivotal shift in the network's operational framework. The source notes that this change aims to enhance compatibility and attract a broader developer community.
Transition to Sei Giga Upgrade
The transition, driven by the approved SIP-3 proposal, will phase out the network's CosmWasm smart contracts and native Cosmos transactions. Sei Network is implementing the Sei Giga upgrade, which aims to streamline its blockchain by eliminating hundreds of thousands of lines of code. This overhaul is expected to enhance performance, allowing the network to process over 200,000 transactions per second.
Importance of the Upgrade
Jay Jog, co-founder of Sei Labs, emphasized the necessity of this change, stating that increasing speed requires either more power or a reduction in complexity. As the network prepares for this transition, users holding Cosmos-native assets are urged to convert their holdings to native USDC before the deadline in late March 2026 to avoid potential asset loss.
Conversion Recommendations
This includes:
- USDC via Noble (USDCn)
User Guidance
Sei Labs is actively encouraging users to take the necessary steps to safeguard their investments during this critical period.
As Sei Network transitions to an EVM-only chain, the cryptocurrency landscape is also witnessing significant developments for Stellar (XLM) between 2027 and 2030. For more details, see Stellar outlook.
