How Hyperliquid works

For endpoint selection, symbols, quiet streams, replay, reconnects, freshness, and peering, see streaming troubleshooting.

For the protocol-level picture, including HyperBFT consensus, HyperCore, HyperEVM, API servers, nodes, and public rate limits, see How Hyperliquid's infrastructure works.

Hyperliquid nodes write raw protocol records to disk. Dwellir exposes available raw feeds through gRPC, while the historical archive preserves native files for longer-term workflows.

Data written by the node

Order books and derived data

V3 market streams expose typed live views without backfill. Use Archival data or indexed history when you need historical coverage.

Order-book reconstruction requires a snapshot or another known state seed followed by ordered diffs. Raw diffs alone are insufficient. For trades, a match can contain multiple makers. Within one block, group fills by (coin, tid). Across blocks, include block_number or block_time because tid is not globally unique.

Why Build on Hyperliquid?

Hyperliquid is a high-performance Layer 1 blockchain purpose-built for decentralized trading, offering both EVM compatibility through HyperEVM and specialized L1 features through gRPC streaming.

Blazing Fast Performance

• Sub-second finality - Near-instant transaction confirmations
• 200,000 orders/second - Unprecedented throughput for DeFi
• Predictable low fees - Stable and minimal transaction costs

Dual API Architecture

• HyperEVM - Full EVM compatibility for Solidity smart contracts
• L1 gRPC Streaming - Real-time order books and market data
• Native Trading Primitives - Built-in support for spot and perpetuals

Trading-Optimized Infrastructure

• Fully on-chain order books - No off-chain components
• HyperBFT consensus - Optimized for trading performance
• Real-time market data - Stream fills, trades, and order updates

Quick Start with Hyperliquid

Pricing and access

Dwellir provides HyperEVM JSON-RPC and HyperCore trading data, including Info, gRPC, and Order Book endpoints. An EVM RPC endpoint alone does not include HyperCore market streams.

On the shared cluster, add gRPC ($299/month) or Order Book ($199/month) access to an API plan. Both add-ons are metered: each streamed message costs 1 API credit.

A Dedicated Node Cluster starts at $4,000/month and 2 dedicated backend nodes. HyperEVM JSON-RPC, Info, gRPC, and Order Book access are included and unmetered. There are no separate gRPC or Order Book add-on fees.

HyperEVM JSON-RPC is sold through the Dwellir API platform on the same plans as every other network, billed at 1 API credit per response. Create an API key in the dashboard and use the HyperEVM endpoint:

Installation & Setup

Network Information

API Reference

HyperEVM JSON-RPC API

HyperEVM provides full Ethereum compatibility, supporting all standard JSON-RPC methods for smart contract deployment and interaction.

EVM Integration Examples

Order Book WebSocket API

Access real-time L2 and L4 order-book data through the Order Book WebSocket API:

L1 gRPC Streaming API

Access Hyperliquid's native Layer 1 features through our specialized gRPC interface:

Available gRPC Streams

• Order Book Snapshots - Generated snapshots through the snapshot RPCs
• Block Streaming - Real-time block updates
• Trade Streams - Live trade execution data
• Fill Streams - Order fill notifications

Quick gRPC Example (V3)

Common Integration Patterns

Algorithmic Trading

Combine HyperEVM smart contracts with L1 streaming for sophisticated trading:

// Deploy strategy contract via HyperEVM
const strategy = await deployContract(strategyABI, strategyBytecode);

// Stream blocks via gRPC for trading data
const blockStream = grpcClient.StreamBlocks();
blockStream.on('data', async (block) => {
  const signal = analyzeBlockData(block);
  if (signal.shouldTrade) {
    await strategy.executeTrade(signal.params);
  }
});

Market Making

Provide liquidity using real-time data:

# Monitor block data via gRPC
for block in stub.StreamBlocks(timestamp):
    data = analyze_block(block)
    if data.spread > target_spread:
        # Place orders via HyperEVM
        place_limit_orders(provider, spread)

DeFi Composability

Build complex DeFi applications:

// Leverage Hyperliquid's native features
contract YieldVault {
    function harvestAndCompound() external {
        // Access perpetuals for hedging
        // Use spot for liquidity
        // Compound yields automatically
    }
}

Use Cases

Perpetuals Trading

Leverage Hyperliquid's native perpetuals with up to 40x leverage (BTC), fully on-chain order books, and sub-second execution.

Spot Trading

Access deep liquidity for spot markets with minimal slippage and predictable fees.

Market Making

Provide liquidity using HyperEVM smart contracts combined with L1 streaming for optimal spreads.

Cross-Chain Arbitrage

Build bridges and arbitrage bots leveraging Hyperliquid's speed advantage over other chains.

Agent Skill

The Hyperliquid agent skill gives AI coding agents procedural knowledge for building on Hyperliquid through Dwellir's infrastructure. It follows the open Agent Skills standard, making it portable across 40+ AI coding agents including Claude Code, Cursor, and Windsurf.

Install it with a single command:

npx skills add dwellir-public/hyperliquid-skills

Once installed, the skill automatically activates when your agent encounters Hyperliquid-related tasks. It covers HyperEVM JSON-RPC, the Info API, gRPC streaming, order book WebSocket access, and native API routing for order placement.
