Hyperliquid Prime

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

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. 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 .

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

1. 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. INLINECODE6 / 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. 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:

1. 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.

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.
