  **Protocols**. **Flashblocks on Optimism** is live on every Chainstack [Optimism](https://chainstack.com/build-better-with-optimism/) mainnet node. The Optimism sequencer streams Flashblocks every 250ms, and Chainstack Optimism nodes expose the preconfirmation state through standard JSON-RPC calls with the `pending` block tag. See [Flashblocks on Optimism](/docs/flashblocks-on-optimism) for the full guide, including the Optimism vs. Base differences and performance expectations.

  **Protocols**. **Hyperliquid `/nanoreth`** is live on every Chainstack [Hyperliquid](https://chainstack.com/build-better-with-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. See [Hyperliquid node configuration](/docs/hyperliquid-node-configuration) for the per-method behavior matrix.
