Published June 16, 2026 Hyperliquid Historical Coverage Expands with New Builder and WebSocket APIs GoldRush now gives builders deeper HyperCore history and more ways to stream live Hyperliquid activity. Historical HyperCore coverage starts at block 606,858,021 (2025-05-25T14:32:53Z). From that point onward, fills, orders, trades, funding, and ledger events are retained and queryable through GoldRush. This expands historical access for high-volume /info types like userFillsByTime and candleSnapshot, so builders can query beyond the public Hyperliquid retention window using GoldRush’s dedicated HyperCore historical store. We’ve also added two GoldRush-native builder attribution endpoints to the Hyperliquid Info API:
  • builderFills - fetch the most recent fills attributed to a builder address.
  • builderFillsByTime - fetch builder-attributed fills over a historical time window.
For real-time use cases, the Hyperliquid WebSocket API now includes three new HyperCore streams:
  • userFills - stream live trade fills for one or more wallets.
  • liquidationFills - stream a global feed of liquidation fills across HyperCore.
  • userNonFundingLedgerUpdates - stream live non-funding ledger events, including deposits, withdrawals, transfers, liquidations, vault actions, staking, and rewards.
Wallet-keyed streams support up to 1,000 HyperCore wallet addresses per subscription and are priced at 1 credit per minute connected. Learn more
