Conversation
- WebSocket channel `mempool`: signed Hyperliquid transactions before they are included in a block, on every Hyperliquid product. Live only, served on wss://stream.0xarchive.io/ws, with the Pro, Scale and Enterprise plans. - ws.subscribeMempool(symbol?), ws.unsubscribeMempool(symbol?) and ws.onMempool(); the symbol is optional on this channel only. - STREAM_WS_URL. A client on the default endpoint refuses a mempool subscription before sending; a mempool replay is always refused. - Types MempoolItem, MempoolAction, MempoolSignature and WsMempoolData, with Zod schemas. - wsEndpoint and plans on WsChannelCapability and Capability. - Acks and data messages accept a null coin and symbol. - Version 1.13.0.
… limit State that the unfiltered stream carries the pending transactions our Hyperliquid node receives, and that unfiltered subscriptions share a server-wide capacity limit that does not apply to symbol subscriptions.
