Hyperliquid Prime

Trade on Hyperliquid's perp markets (native + HIP-3) with intelligent order routing and cross-market splitting. Use when the user wants to trade crypto, stocks, or commodities on Hyperliquid, get best execution across fragmented markets, split large orders across multiple venues, compare funding rates, view aggregated orderbooks, or manage positions across multiple collateral types. Routes across both native HL perps (ETH, BTC) and HIP-3 deployer markets. Handles collateral swaps (USDC→USDH/USDT0) automatically during execution when the best liquidity requires it.

Security Scan

The skill's requirements and instructions are internally consistent with a trading/prime-broker SDK, but it requires installing an npm package and on-chain approvals that you should audit and test carefully before using with a mainnet key.

Purpose & Capability

The skill claims to provide prime-broker routing and execution on Hyperliquid perps; the declared requirements (an optional private key for trading, npm package install) and documented behaviors (quotes read-only; execute requires signing) align with that purpose. No unrelated environment variables or binaries are requested.

Instruction Scope

SKILL.md stays within the trading domain and documents both read-only operations and on-chain actions (builder fee approval, DEX abstraction enable, collateral transfers and swaps). These automatic on-chain changes are coherent with the described cross-collateral routing functionality, but they are high-impact actions and require explicit user awareness and confirmation before executing on a wallet with real funds.

Install Mechanism

This is an instruction-only skill, but it instructs users to install the 'hyperliquid-prime' npm package. Installing from the public npm registry is a normal way to obtain an SDK, but it brings moderate risk because arbitrary code will run on your machine. The SKILL.md and plugin file point to a GitHub repo to audit first; you should review that repository and the published npm package before installing.

Credentials

Only an optional HP_PRIVATE_KEY (or privateKey config) is required for trading operations; this is proportional to the skill's purpose. No unrelated secrets or multiple credentials are requested. The SKILL.md documents that read-only calls do not require a key.

Persistence & Privilege

The skill is not always-enabled, does not request system-wide persistence, and does not claim to modify other skills. On-chain approvals and account-level settings are part of the trading workflow (documented), but the skill itself does not request elevated platform privileges.

Assessment

Before installing or using this skill: - Audit the code: review the GitHub repository and the exact npm package version (hyperliquid-prime) to ensure the implementation matches the documentation. - Test on testnet: use the testnet mode and a throwaway wallet to observe behavior (especially builder-fee approval, DEX abstraction enable, and collateral swap flows). - Protect keys: never use a mainnet wallet with significant funds. Prefer ephemeral wallets or an offline signer/HW wallet for signing transactions if supported. - Review approvals: the SDK will auto-send a one-time builder-fee approval and may enable account features; check on-chain approvals and learn how to revoke them (e.g., ERC-20 allowance revocation) before granting permissions. - Verify fee recipient and opt-out: confirm the builder fee recipient address and the documented opt-out mechanism (builder: null) are legitimate in the upstream repo. - Consider reviewing package integrity: verify npm package integrity (checksums) and that the npm package source matches the GitHub repository linked in the SKILL.md/plugin file. Note: The registry header showed 'Source: unknown' while the included plugin file and SKILL.md link to a GitHub repo—that inconsistency is worth clarifying with the publisher before use.

A TypeScript SDK that acts as a prime broker layer on top of Hyperliquid's perp markets — both native (ETH, BTC) and HIP-3 deployer markets. Automatically discovers all markets for an asset, compares liquidity/funding/cost, and routes to the best execution — or splits across multiple venues for optimal fills with automatic collateral swaps.

When to Use This Skill

• Trading crypto, stocks (AAPL, NVDA, TSLA), indexes, or commodities (GOLD, SILVER) on Hyperliquid
• Need best execution across multiple perp markets (native + HIP-3) for the same asset
• Splitting large orders across venues for better fills and lower price impact
• Comparing funding rates across different collateral types
• Aggregated orderbook view across fragmented markets
• Managing positions that may be spread across multiple collateral types
• Automatic collateral swaps (USDC → USDH, USDT0) when non-USDC markets offer better prices

Quick Start

Installation

npm install hyperliquid-prime

Read-Only Usage (no wallet needed)

import { HyperliquidPrime } from 'hyperliquid-prime'

const hp = new HyperliquidPrime({ testnet: true })
await hp.connect()

// Get all perp markets for an asset (native + HIP-3)
const markets = hp.getMarkets('ETH') // or 'TSLA', 'BTC', etc.

// Get routing quote for best execution
const quote = await hp.quote('TSLA', 'buy', 50)
const quoteWithLev = await hp.quote('TSLA', 'buy', 50, { leverage: 5, isCross: true })

// Aggregated orderbook
const book = await hp.getAggregatedBook('TSLA')

// Funding rate comparison
const funding = await hp.getFundingComparison('TSLA')

await hp.disconnect()

Trading (wallet required)

const hp = new HyperliquidPrime({
  privateKey: '0x...',
  testnet: true,
})
await hp.connect()

// Quote then execute (recommended)
const quote = await hp.quote('TSLA', 'buy', 50, { leverage: 5, isCross: true })
const receipt = await hp.execute(quote.plan)

// One-step convenience
const receipt2 = await hp.long('TSLA', 50, { leverage: 5 })
const receipt3 = await hp.short('TSLA', 25, { leverage: 3, isCross: false })

// Split across multiple markets for better fills
const splitQuote = await hp.quoteSplit('TSLA', 'buy', 200, { leverage: 4 })
const splitReceipt = await hp.executeSplit(splitQuote.splitPlan)
// Or one-step: await hp.longSplit('TSLA', 200)

// Unified position view
const positions = await hp.getGroupedPositions()

await hp.disconnect()

CLI

# Show all perp markets for an asset (native + HIP-3)

Important: Fees & Automatic Actions

Builder Fee: A 1 basis point (0.01%) builder fee is charged by default on all SDK-executed orders via Hyperliquid's native builder fee mechanism. On the first trading order from a wallet, the SDK sends an on-chain approval transaction to authorize this fee. To disable entirely, set builder: null in the config.

Collateral Swaps (Split Orders Only): When executeSplit() routes orders to non-USDC collateral markets, the SDK automatically:

1. Enables DEX abstraction on the user's account
2. Transfers USDC from the perp account to the spot account
3. Places a spot order to swap USDC into the required collateral token (e.g., USDH, USDT0)
4. A 1% buffer is added to swap amounts to account for slippage

These actions only occur during split order execution and only when the best liquidity requires non-USDC collateral.

Read-Only Operations: Quotes, orderbooks, funding comparisons, and market discovery require no wallet, no fees, and perform no on-chain actions.

Credentials: Trading operations require a private key via HP_PRIVATE_KEY environment variable or the privateKey config option. The key is used to sign transactions sent to the Hyperliquid API. Source code is available for audit at https://github.com/mehranhydary/hl-prime.

User Confirmation Flow: The SDK uses a quote-then-execute pattern as the confirmation mechanism:

1. quote() / quoteSplit() are read-only — they return an execution plan with estimated prices, markets, and costs. No on-chain actions are taken.
2. The caller reviews the plan (programmatically or via CLI output).
3. execute() / executeSplit() must be explicitly called to perform on-chain actions (place orders, approve fees, swap collateral).
4. One-step convenience methods (long(), short(), longSplit(), shortSplit()) combine both steps — use quote-then-execute for explicit control.

Implementation Note: This skill bundle contains instructions only (SKILL.md). The SDK implementation must be installed separately via npm install hyperliquid-prime. The source code is open-source and available for audit at the GitHub repository before installation.

How Routing Works

When you call hp.quote("TSLA", "buy", 50), the router:

1. Fetches the orderbook for every TSLA market
2. Simulates walking each book to estimate average fill price and price impact
3. Scores each market using:
   • Price impact (dominant) — cost in basis points to fill
   • Funding rate (secondary) — prefers favorable funding direction
   • Collateral swap cost (penalty) — estimated cost to swap into the required collateral
4. Selects the lowest-score market and builds an execution plan

For split orders (quoteSplit), the router merges all orderbooks, walks the combined book greedily to consume the cheapest liquidity first across all venues, and builds split execution legs. Collateral requirements and swaps are estimated and executed at executeSplit(...) time using live balances. If leverage is included in the quote options, execution applies that leverage per market leg before order placement.

For single-market orders, leverage included in quote(...) is carried into the execution plan and applied before the order is sent.

Configuration

interface HyperliquidPrimeConfig {
  privateKey?: `0x${string}` // Required for trading
  walletAddress?: string       // Derived from privateKey if not provided
  testnet?: boolean            // Default: false
  defaultSlippage?: number     // Default: 0.01 (1%)
  logLevel?: 'debug' | 'info' | 'warn' | 'error' | 'silent'
  prettyLogs?: boolean         // Default: false
  builder?: BuilderConfig | null // Builder fee (default: 1 bps, null to disable)
}

Builder Fee

A 1 basis point (0.01%) builder fee is included by default on all SDK-executed orders via Hyperliquid's native builder fee mechanism. The fee is auto-approved on the trader's first order. Set builder: null to disable, or provide a custom { address, feeBps } to override.
