Sei v6.7 is now live on mainnet.
But the most important part of this upgrade isn't just performance. It's what Sei is preparing for next.
Proposal #125 has passed, and validators have upgraded pacific-1 to v6.7.
One of the key changes is the governance switch for Eidos, which will enable the next step toward migrating EVM state from memIAVL to FlatKV.
Important distinction: the migration itself has NOT happened yet. It will follow in a separate step.
So why does this matter?
Sei is also simplifying its architecture by removing 184,000 lines of legacy code across 305 merged PRs from 17 contributors.
The upgrade brings several other improvements:
• Faster EVM execution through in-memory contract bytecode caching and optimized BLOCKHASH lookups.
• More resilient RPC, WebSocket and query endpoints, with per-client limits to prevent heavy users from degrading service for everyone.
• Stronger protocol validation and security review.
• Simpler node setup with built-in seed peers, allowing new nodes to join without manual peer configuration.
The bigger picture is that Sei is continuing to refine its EVM infrastructure while reducing legacy complexity.
For developers, that means a cleaner foundation to build on. For the network, it means better execution efficiency and more resilient public infrastructure.
And the FlatKV migration is the next milestone to watch.
Sei v6.7 is live. The architectural transition is still ahead.
