The Sei mainnet has completed the v6.6 upgrade, officially launching two major upgrades under the Giga initiative: Ares and Eidos. Following the Ares upgrade, the v2 executor will be gradually phased out; the Eidos upgrade enables two years of on-chain state separation by migrating EVM historical data to a dedicated database. This upgrade resolves over 30 issues, optimizes node synchronization efficiency, consensus timeout parameters, error-prone configurations, and data pruning mechanisms, while enhancing developer-facing features such as receipt generation, JSON-RPC error handling, and historical call tracing.
