# HyperCore vs. HyperEVM

> What HyperCore and HyperEVM are, how they differ, and which one you actually connect to when you integrate with Hyperliquid.

Hyperliquid isn't a single chain — it's two components with different jobs. Understanding the split matters before you integrate, because it determines what you can and can't access programmatically.

## HyperCore

HyperCore is Hyperliquid's native chain, purpose-built to process trades with very low latency. It runs the on-chain order book, perpetuals, and spot markets that make Hyperliquid a trading venue in the first place.

HyperCore is **not** an open, permissionless environment in the way most L1s are. Access to it is fully controlled by Hyperliquid — you can't run your own HyperCore node, and there's no general-purpose smart contract layer to deploy to. It exists to make the exchange fast, not to be a programmable chain third parties build directly on top of.

## HyperEVM

HyperEVM is the EVM-compatible chain that bridges Hyperliquid into the broader Ethereum ecosystem. It's what lets developers deploy standard Solidity smart contracts, use familiar EVM tooling, and interact with Hyperliquid using the same JSON-RPC methods you'd use on any other EVM chain.

Unlike HyperCore, HyperEVM is the piece you can actually run infrastructure for — nodes are permissionless, and it's the layer meant for third-party integration and contract deployment.

## Key differences

|                       | HyperCore                                          | HyperEVM                            |
| --------------------- | -------------------------------------------------- | ----------------------------------- |
| **Purpose**           | Native trading engine (order book, perps, spot)    | EVM-compatible smart contract chain |
| **Node access**       | Controlled by Hyperliquid — you cannot run a node  | Permissionless — you can run a node |
| **Programmability**   | No general-purpose contract layer                  | Standard EVM smart contracts        |
| **How you integrate** | Indirectly, via HyperEVM or Hyperliquid's own APIs | Directly, via standard JSON-RPC     |

## Which one does Uniblock connect to?

Because HyperCore access is controlled by Hyperliquid and isn't open to node operators, Uniblock's JSON-RPC endpoint routes to **HyperEVM** — the chain you can actually query and transact against with standard EVM tooling.
