HyperEVM is the decentralized half of Hyperliquid, a 1-second blocktime EVM chain. It was already supported on the GoldRush Foundational API for token balances and historical transactions, but Streaming API support depended on a viable WebSocket support on the node level.
Previous limitations
- HyperEVM nodes initially didn’t expose WebSockets, so real-time delivery was harder than it should’ve been.
- OHLCV/candlestick use cases were especially painful, JSON RPC-only pulls were too slow for high-frequency builders.
What’s new
- WebSockets are now shipped as part of the HyperEVM node, unlocking first-class Streaming API support.
- Gapless streaming remains a core guarantee, and so we automatically backfill if we disconnect and there won’t be any missing data.
- OHLCV streams are now practical on HyperEVM, so you can “one-shot” candlestick data directly into bots, dashboards, and agents.
