/nanoreth is live on every Chainstack Hyperliquid mainnet node. Append /nanoreth to your endpoint URL to get system transactions included in eth_getBlockByNumber, eth_getBlockReceipts, and direct hash lookups. The default /evm path is unchanged — hl-node-compliant, system transactions stripped from block-shaped responses. Find both paths in the console under Access and credentials on any Hyperliquid node.
See Hyperliquid node configuration for the per-method behavior matrix.
