Promote with Leviathan NewsSei v6.4 is live on mainnet, adding protocol-level capability to block inbound IBC transfers — though it won't activate until a separate governance proposal passes. The upgrade advances SIP-3, the May 2025 community proposal to deprecate CosmWasm and all native Cosmos functionality in favor of an EVM-only architecture. Users holding Cosmos-native assets like ATOM, USDC.n, or Kava USDT on Sei should swap to EVM equivalents or bridge back to origin chains before governance flips the switch. Future releases will also disable outbound IBC transfers and remove Sei's native oracle.
