This article explores the thoughts surrounding the price mechanism and market philosophy of decentralized exchanges triggered by the JELLYJELLY event, analyzing the differences in the perpetual futures algorithms of three major platforms and their financial philosophies. By comparing the index price, mark price, and funding rate of the platforms, it reveals their respective trading styles and user groups, emphasizing that traders need to have an in-depth understanding of the value judgments behind the market philosophy of the platform they choose.

The Price Mechanism and Market Philosophy Behind Futures Trading

Introduction: Reflections on the JELLYJELLY Incident

In March 2025, the JELLYJELLY Futures Trading caused a market stir on the Hyperliquid platform. The contract price skyrocketed by 429% in a short period, nearly triggering massive liquidations. If liquidations occur, short positions will be forced into the on-chain liquidity vault HLP, resulting in significant floating losses. Some centralized exchanges also quickly launched perpetual contract trading for JELLYJELLY.

As the clearing was about to occur, Hyperliquid’s validators intervened with an urgent vote to forcibly delist the Futures Trading and freeze trading. This incident sparked a discussion about the essence of “decentralized” exchanges: who ultimately determines the price on decentralized platforms? Who should bear the risk? Is the algorithm truly neutral?

This article will use this event as a starting point to analyze the algorithmic differences in the core mechanisms of perpetual Futures Trading on the three major platforms, focusing on index price, mark price, and funding rate (, and explore the financial philosophies and risk transmission mechanisms behind them. We will see how different algorithms shape trading styles, serve different types of traders, and how they affect traders’ survival capabilities in market volatility.

This is not only an analysis of futures trading technology, but also a philosophical reflection on the design of market order.

Three Key Elements of Perpetual Futures Trading

Perpetual Futures Trading consists of three key elements:

Index Price: Tracks changes in spot market prices and serves as a theoretical benchmark. Hyperliquid refers to this as the Oracle Price ) and the oracle price (.
Mark Price: The decisive price used to calculate unrealized profit and loss, trigger liquidation, and other key events.
Funding Rate: An economic mechanism that connects the spot and Futures Trading markets, guiding the Futures Trading price back to the spot.

Platform Algorithm Comparison

) Index Price/Oracle Price

The oracle prices of Hyperliquid are independently constructed by validator nodes, using a weighted median method to resist extreme fluctuations, with an update frequency of once every 3 seconds. This method is better at resisting price manipulation, but the updates are relatively slow.

Mark Price

The marking price algorithm of Binance is based on the median of the contract market buying and selling price, transaction price, and impact price, combined with EMA processing. This method smooths price changes, making it suitable for large capital stable layouts.

OKX only uses the midpoint price of the order book for buying and selling. The prices are extremely sensitive to small transactions and fluctuate significantly, making it suitable for high-frequency trading.

Hyperliquid integrates multiple price sources: the EMA of the difference between Oracle prices and contract mid-prices, the median of buy and sell prices within the platform compared to transaction prices, and the weighted median of perpetual mid-prices from multiple CEXs. Validators are responsible for updating prices and conducting consistency verification, forming a certain degree of “algorithmic democracy”.

Funding Rate

Hyperliquid introduces a premium index based on the Binance model, using Oracle prices instead of index prices. To compensate for the slow price regression, Hyperliquid adopts a high funding rate of ###, which can reach up to 4%/hour in extreme cases (, calculated based on Oracle prices rather than marked prices, and charges on an hourly basis.

Binance’s funding rate settlement period is relatively long, usually 8 hours, considering the order book depth and borrowing rates, providing institutional investors with stable funding cost expectations.

The funding rate algorithm of OKX is relatively simple and has large fluctuations, making it suitable for aggressive short-term strategies.

Conclusion: The Game Between Algorithms and Human Nature

Different trading platforms reflect their understanding of the essence of the market and value judgments through algorithmic design. Binance pursues stability and predictability, OKX embraces market volatility, while Hyperliquid attempts to establish on-chain consensus. However, the JELLYJELLY incident revealed that even decentralized systems can struggle to completely avoid human intervention in extreme situations.

In the future financial world, algorithms will continue to expand their influence. However, we must recognize that every algorithm embodies value judgments. When traders choose a platform, they are not just selecting trading tools, but also choosing a market philosophy. Whether pursuing freedom, fairness, or transparency, ultimately, they must take responsibility for their choices.

Let us always maintain a sense of awe towards the market.
