HLP Vault: The Liquidity Counterparty
HLP (Hyperliquidity Provider) is Hyperliquid's native USDC vault that acts as the counterparty to all perp trades on the exchange. When you long ETH on Hyperliquid, HLP is your counterparty — taking the short side and earning the spread. Understanding HLP is essential for anyone considering depositing USDC or trading on Hyperliquid.

How HLP Works as the Counterparty
HLP operates as a continuous market-maker. Every perp trade on Hyperliquid has HLP on one side. The protocol aggregates all HLP positions and manages net delta exposure through internal hedging. The key insight is that HLP is delta-neutral by design — the protocol hedges net exposure so HLP earns the spread without directional market risk on the aggregate book.
1
Trader opens $5M ETH Long @ $3,500
Trader deposits $50K margin (10x leverage) and goes long ETH perp.
HLP automatically becomes the short counterparty at $3,500.
2
HLP records short position, earns spread
HLP's internal ledger records -$5M ETH exposure.
Trade generates $5,000 in spread income (0.1% of notional, split maker/taker).
HLP's share: ~$3,750 after protocol fees.
3
Protocol hedges net delta
If HLP has net short ETH exposure, the strategy module hedges via external perps
(Binance, Bybit) or reduces position limits. Net delta stays near zero.
4
Trader pays 8h funding (longs pay shorts)
Every 8 hours, if ETH perp > oracle index, longs pay shorts.
HLP (as short) receives funding: ~$500 per 8h on $5M notional.
This accumulates daily into HLP's earning pool.
HLP Net PnL (per epoch)
= Spread Earnings + Funding Received - Deleveraging Costs - Hedge Slippage
If ETH rises 5%, trader's long wins $250K. HLP's short loses $250K. But spread + funding earned the trader paid ~$10K in fees. Net: HLP loses $240K but earned $10K in fees. Risk vs reward tradeoff.

Market Condition Scenarios
📊 Trending Market (Bull)
ETH rises 20%. Long traders win. HLP short loses on positions but earns massive funding (longs pay shorts). Net can be positive or negative depending on hedge quality.
APY: -5% to +40%
📈 High Volatility
Big funding rates, more liquidations = more spread income. Oracle gaps can cause unexpected PnL. Best for HLP in sideways-but-volatile conditions.
APY: 10–30%
📉 Bear Market / Crash
Longs get wiped. Shorts win. HLP (which hedges) may see net positive if shorts win more than spreads/liquidation losses. Funding payments from liquidated longs go to HLP short.
APY: 5–25%
😴 Range-Bound / Low Vol
Funding rates near zero. Low volume = less spread income. HLP earns base spread from order flow. Lowest APY period but also lowest risk.
APY: 3–8%

Capital Efficiency
High — USDC only, no multi-asset drag
Moderate — multi-asset exposure requires reserves
High for large markets, low for small ones
Key Insight:
GLP holders absorb both market risk AND asset volatility. HLP depositors take on
strategy risk but avoid impermanent loss since all deposited assets are USDC.
During 2022–2023 ETH bear market, GLP recovered faster than expected because shorts
won — but during 2024 bull market, GLP holders saw losses from long traders winning.
HLP's delta-neutral design is more stable but earns less during trending markets.
HLP Risk Management & Deleveraging
Position Monitoring
Real-time tracking of net HLP delta across all markets. Internal risk dashboard shows current exposure vs limits.
→
Delta Hedging
When net short ETH exceeds threshold, protocol opens long ETH perp on external venue to flatten delta. Hedge costs reduce spread income.
→
Risk Limit Breach
If exposure exceeds hard limit, new positions that increase net exposure face higher fees (spread doubled) or are rejected. This protects HLP from runaway delta.
→
Deleveraging
In extreme scenarios, HLP reduces position sizes by closing internal positions. This creates price impact on Hyperliquid itself — large deleveraging trades can move the market.
Why HLP Matters for Hyperliquid
Capital Efficiency for Retail
HLP democratizes market-making. Previously, earning from spread and funding required building a trading operation and managing delta hedges. HLP lets anyone deposit USDC and earn the same income stream with one click.
Deep Liquidity for Traders
HLP's always-on liquidity means Hyperliquid traders get tight spreads even in volatile conditions. HLP's capital backs every order, eliminating the order book depth problems that plague smaller exchanges.
Sustainable Fee Model
Unlike protocols that subsidize liquidity with token incentives, HLP's returns come from real trading activity. When volume is high, HLP earns more. When volume drops, HLP earns less. This aligns LP returns with actual protocol health.
Risk-Sharing Structure
HLP depositors knowingly take on market-making risk. The protocol's delta hedging reduces directional exposure, but HLP depositors still face scenario where oracle gaps create losses that exceed fee income. Full transparency of this risk is critical.
- What is the HLP vault on Hyperliquid?
- HLP (Hyperliquidity Provider) is a permissionless vault where anyone can deposit USDC to act as the liquidity provider and market-maker for Hyperliquid's perpetual futures. The vault's USDC is used to take the other side of trader positions — when a trader opens a long, HLP becomes the short counterparty. In return, HLP depositors earn the trading fees (spread) and any funding rate payments when HLP is on the profitable side of positions. HLP is fully on-chain and non-custodial — deposited USDC are held in the protocol's smart contracts.
- How does HLP generate returns for depositors?
- HLP returns come from three sources: (1) Maker spread — HLP earns a small spread on every trade it acts as counterparty to, typically 0.02–0.05% of notional per trade. (2) Funding rate payments — if HLP holds the short side of a market in contango (perp price > index), longs pay shorts and HLP receives those payments. (3) Price improvement — when HLP provides liquidity tighter than the spread, traders get better fills and HLP earns the difference. Annual yield for HLP depositors has varied widely — from 5% to over 50% during high-volatility periods when funding rates spike.
- How is HLP different from GMX's GLP pool?
- GMX's GLP is a multi-asset pool (USDC + other assets like ETH, BTC, USDC) that provides liquidity for both longs and shorts simultaneously. GLP holders bear both trader PnL directions — if traders win, GLP absorbs losses; if traders lose, GLP gains. HLP is simpler: it's USDC-only, and the protocol runs internal hedging strategies so HLP's net exposure stays near zero while capturing spread income. Both models eliminate individual counterparty risk for traders, but HLP's USDC-only design is more capital efficient and avoids impermanent loss from multi-asset volatility.
- Can HLP depositors lose money?
- Yes. HLP depositors face two primary risks: (1) Net PnL risk — if the protocol's hedging strategy fails or if there's a large price gap (oracle lag during fast markets), HLP can absorb significant trader losses. In a sustained bull market where longs win consistently, HLP shorts absorb those losses. (2) Deleveraging risk — if HLP's net delta becomes too large, the protocol may need to reduce position sizes, limiting earning potential. During extreme volatility events like Black Thursday or FTX collapse, HLP returned negative as funding rates and oracle gaps created large adverse PnL.
- How does HLP handle hedging and risk limits?
- HLP uses an internal delta-neutral strategy to manage its net exposure. When HLP has many short positions (counterparty to longs), the protocol either accumulates short exposure (bearish delta) or hedges via external venues like Binance or Bybit perp markets. Risk limits are set by governance — if HLP's net exposure exceeds a threshold, new positions that would increase that exposure are subject to higher fees or size limits. Deleveraging occurs automatically when risk limits are breached, protecting HLP from unbounded downside.
- What is the difference between HLP and GM Pools?
- GM Pools (used by GMX v2 and similar protocols) are a generalization of the GLP model where liquidity is partitioned into isolated vaults per market. GM Pools allow more fine-tuned risk management — each market has its own pool, and LPs can choose which markets to provide liquidity for. HLP is simpler and unified — one vault for all markets. GM Pools tend to be more capital efficient for large markets but introduce complexity. HLP's simplicity makes it more accessible for retail depositors who just want one USDC vault to deposit into.
- How is HLP's APY calculated and reported?
- HLP APY is calculated as: (fees earned + funding received - losses) / total HLP deposits over a time period, annualized. The protocol reports a rolling 30-day APY, but this can be misleading during high-volatility periods. Funding rates spike during trending markets (sending APY to 50%+), then normalize when markets consolidate. Historical APY for HLP has ranged from single digits during bear markets to 30-40% during bull markets with high perp funding. Depositors should understand that high APY periods often coincide with high risk conditions.
- What happens to HLP during a liquidation cascade?
- During a liquidation cascade — a rapid multi-million dollar long liquidation that gaps the oracle price down — HLP (as short counterparty) earns those liquidations. But if the cascade continues and oracle prices lag real market prices by several seconds, HLP's short positions become over-collateralized and the protocol may freeze or limit new positions. If oracle prices gap significantly, HLP can face sudden large losses if the oracle catches up to real prices and positions that seemed profitable now have huge unrealized losses. The 2022 ETH crash was particularly instructive for GMX's GLP holders who absorbed massive liquidation payments that initially looked like profits but were reversed as prices continued to fall.
