HyperEVM is Hyperliquid’s EVM-compatible chain — the layer where you deploy standard Solidity contracts and interact with Hyperliquid using the same JSON-RPC methods you’d use on any other EVM chain. Uniblock exposes HyperEVM through its unified JSON-RPC endpoint, so you get low-latency routing and automatic provider failover behind one API key.
HyperEVM is the permissionless, contract-programmable half of Hyperliquid. HyperCore — the native order book — is reached through the Info API and WebSockets instead. See HyperCore vs. HyperEVM.

​
Endpoint

Send a POST request to the unified JSON-RPC endpoint with the chain ID in the query string:
Include the JSON-RPC method and params in the request body, authenticated with your x-api-key header.
