Sei Atlantic (testnet) will be undergoing a netowrk upgrade to v6.8 on 2026-11-10 ~16 UTC. This release removes the Cosmos gRPC and gRPC-Web servers, Rosetta, and the tokenfactory module; state proofs are now off by default. Per-IP RPC rate limiting is enabled by default on EVM JSON-RPC and CometBFT RPC endpoints. Brief interruptions to RPC availability may occur on that date.
RPC Changes: - batch_request_limit — EVM JSON-RPC batch_request_limit default has been reduced from 1000 to 100; requests exceeding this limit will be rejected. - Cosmos gRPC and gRPC-Web — These servers have been removed from seid and are no longer available. - Rosetta API — The Rosetta API has been removed and is no longer available. - per-IP rate limiting — EVM JSON-RPC and CometBFT RPC now enforce per-IP rate limiting by default; users behind reverse proxies or load balancers may experience rate-limit errors if proxy IP configuration is not set.
