HIP-3 Cross Margin Is Live

Hyperliquid has enabled cross margin for HIP-3 tokens on mainnet. This is a feature that sounds technical in isolation but has significant practical implications: spot tokens listed through Hyperliquid's permissionless DEX standard can now be used as collateral for trading. If you hold HIP-3 tokens, those holdings can now support your perpetual futures positions without needing to sell them for USDC first.

This feature is only compatible with unified account mode, which means traders must opt into unified accounts to access HIP-3 cross margin. For those already using unified accounts, the change is automatic — HIP-3 tokens in your account are now recognized as collateral.

What Is HIP-3

Before diving into the cross margin implications, it is worth understanding what HIP-3 is and why it matters.

HIP-3 is Hyperliquid's standard for permissionless spot token listing. It defines a standard for listing spot tokens on HyperCore — the same high-performance order book that powers Hyperliquid's perpetual futures. Tokens listed via HIP-3 benefit from sub-second finality, deep liquidity infrastructure, and the professional trading interface. The listing process is permissionless, meaning anyone can list a token that meets the HIP-3 specification without approval from the Hyperliquid team.

The standard includes built-in market making via a protocol-level automated liquidity mechanism, ensuring every HIP-3 token has baseline liquidity from the moment it is listed. This combination of permissionless listing and protocol-guaranteed liquidity has made HIP-3 the primary venue for new token launches in the Hyperliquid ecosystem.

How Cross Margin Works With HIP-3 Tokens

Cross margin on Hyperliquid allows all assets in a unified account to serve as collateral for trading positions. Previously, this primarily meant USDC and a limited set of approved spot assets. With HIP-3 cross margin, the set of recognized collateral expands to include tokens listed via HIP-3.

When you hold HIP-3 tokens in your unified account, the system assigns a collateral value based on the current market price and a haircut percentage. The haircut — a discount applied to market value — accounts for volatility and liquidity risk. A highly liquid token might receive a smaller haircut, while a newer, less liquid token would receive a larger one.

For example, if you hold $10,000 worth of a HIP-3 token with a 30% haircut, $7,000 of that value is recognized as available collateral. This $7,000 can support your perpetual futures positions alongside any USDC or other collateral in your account.

The collateral value updates in real time as the HIP-3 token price changes. If the token price drops, your available collateral decreases, potentially affecting your margin requirements for open positions. This is the same dynamic that applies to any non-stablecoin collateral in a cross margin system, and traders need to account for it in their risk management.

Why This Matters

Capital Efficiency

The most direct benefit is capital efficiency. Before HIP-3 cross margin, a trader holding both HIP-3 spot tokens and perpetual futures positions needed to maintain separate capital for each. The spot tokens sat in the account as inert holdings — they had value, but that value could not support trading activity.

Now, the same capital serves dual purposes. You can maintain exposure to HIP-3 spot tokens you believe in while simultaneously using that exposure as collateral for derivatives trading. This is particularly valuable for traders who are long-term holders of certain HIP-3 tokens but also actively trade perpetual futures.

Reduced Selling Pressure

When traders need collateral for futures positions and their capital is locked in spot tokens, the only option previously was to sell those tokens for USDC. This creates selling pressure on HIP-3 tokens during volatile periods — precisely when traders are most likely to need additional margin for their futures positions.

Cross margin reduces this dynamic. Instead of selling tokens to free up collateral, traders can simply let their existing holdings serve as margin. This is better for the trader (who avoids selling at potentially unfavorable prices) and better for the token markets (which experience less forced selling).

DeFi Composability

This update is an important step in the broader composability story of the Hyperliquid ecosystem. Composability — the ability for different financial primitives to interact and build on each other — is one of DeFi's defining advantages over traditional finance.

With HIP-3 cross margin, spot token holdings, perpetual futures positions, and collateral management are all unified into a single system. A trader's spot portfolio directly influences their derivatives trading capacity. This creates feedback loops and interaction effects that enable strategies impossible on platforms where spot and derivatives are siloed.

Consider a concrete example. A trader launches a token via HIP-3 and wants to hedge their exposure via perpetual futures. Previously, this required selling tokens for USDC to fund the hedge. Now, the spot allocation itself can collateralize the hedge, allowing full exposure maintenance alongside risk management.

Unified Account Requirement

HIP-3 cross margin is only available in unified account mode. In legacy mode, spot holdings and perpetual futures positions are managed in separate sub-accounts with independent margin calculations — there is no mechanism for spot assets to collateralize futures positions. Unified account mode merges everything into a single margin calculation, which is a prerequisite for cross-collateralization. If you have not yet migrated, this is another strong reason to do so.

Risk Considerations

Using volatile spot tokens as collateral introduces risks that traders must understand.

Correlation risk is the primary concern. If you hold a HIP-3 token as collateral and use it to support a leveraged long position on a correlated asset, a market downturn hits you on both sides — your collateral value drops while your leveraged position also loses money. This double exposure can accelerate liquidation in a way that pure USDC collateral would not.

Liquidity risk matters for less actively traded HIP-3 tokens. The haircut partially accounts for this, but extreme market conditions can cause liquidity to dry up faster than the model anticipates.

Haircut changes are also possible. A token that qualifies for a 20% haircut today might see that increase to 40% if its liquidity profile deteriorates, reducing your available collateral without any change in your holdings.

The Road Ahead

HIP-3 cross margin is one of several features making Hyperliquid's unified account increasingly powerful. Combined with portfolio margin (now in alpha) and automatic yield on idle assets, the platform is building toward a fully integrated trading environment where every asset in your account works together to maximize capital efficiency.

For HIP-3 token projects, cross margin eligibility adds real utility beyond speculative trading. Being usable as collateral creates organic demand and reduces sell pressure on new listings, strengthening the flywheel between token launches, liquidity, and platform adoption.
