We are upgrading our Sei Mainnet infrastructure to v6.6.1. This is a recommended patch release addressing two critical stability issues affecting RPC and LCD node operators.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
LCD pagination — Pagination that regressed in v6.6.0 has been restored while preserving v6.6 precompile semantics.
