DeFi Takes Over the Leverage Trading Market: The Three Battles of RWA Perpetuals

Introduction: Trillion-Dollar Market Opportunities Are Driving DeFi

Currently, the crypto industry’s approach to RWA (Real-World Assets) mainly involves mapping ownership of tangible assets like government bonds, stocks, and real estate onto the blockchain to improve settlement and custody efficiency. However, this ownership efficiency model alone misses the true engine of the global financial markets — leverage trading.

The source of liquidity in global financial markets isn’t those holding assets statically, but traders seeking directional exposure using leverage. From the US’s 0DTE options market (roughly $50 trillion in monthly nominal value) to offshore CFD markets (around $30 trillion in monthly trading volume), retail investors’ demand for high-leverage, short-term risk exposure is relentless. Yet, existing traditional financial tools fail to meet this demand adequately. DeFi protocols are now targeting this structural gap by building on-chain leverage trading infrastructure.

Explosive Growth of 0DTE Markets and CFDs: Challenging an $80 Trillion Market

Rapid Expansion of the US 0DTE Options Market

Over the past decade, the US options market has undergone fundamental change. According to Cboe Global Markets data, the share of same-day expiry (0DTE) options trading in S&P 500 options has surged from less than 5% in 2016 to 61% today. Monthly nominal trading volume has reached $48 trillion, about 40 times larger than the perpetual contracts traded on major centralized exchanges.

What does this phenomenon reveal? Mathematically, traders’ true need isn’t “options” per se, but pure delta-one exposure — a mechanism where profit and loss are linearly and symmetrically reflected against asset price movements.

However, 0DTE options force traders into unnecessary “insurance” functions. Traders seeking only directional exposure are burdened with nonlinear risks like time decay (theta) and volatility changes (vega). Unless the underlying asset’s price appreciation outpaces the decay of time value, even correct directional bets can lead to losses in leveraged trading.

Offshore CFD Markets: An $30 Trillion Unregulated Battlefield

Outside the US, retail leverage demand is primarily met through CFDs (Contracts for Difference), with monthly average trading volume reaching $30 trillion by 2025. CFDs excel at providing linear, delta-one payoff structures, but their market operation models have critical flaws.

Most CFD brokers adopt a B-Book (market-making within the platform) model, where the broker acts as the counterparty to traders. This means trader losses directly translate into broker profits. Operating in a “black box” with little transparency, brokers have the technical and economic incentives to manipulate prices, slippage, and execution speed.

Weekend Price Gaps and Structural Challenges of Perpetual RWAs

Challenge 1: Oracle Price Feed Disruptions During Market Closures

The essence of RWA perpetual contracts is “price discovery mirror.” Since US stocks and commodities aren’t traded 24/7, when Nasdaq or CME halt trading over weekends or at night, oracle data sources experience disconnections.

Professional market makers aim for neutral positions without directional bets, hedging risks immediately in spot or futures markets. When markets are closed, hedge channels shut down, preventing market makers from adjusting hedges. To avoid this unavoidable risk, they either cancel orders or add substantial risk premiums to quotes. This causes traditional order book models to see nonlinear widening of spreads over weekends, sometimes several times the normal.

Challenge 2: “Gap Risk” at Monday Open

Crypto-native trading, operating 24/7, typically features continuous price curves, with liquidation engines having ample time to liquidate positions during price drops.

In contrast, in the RWA space, accumulated price pressures during market closures are suddenly released at Monday’s open. Large gaps can cause the liquidation engine to encounter “price fractures,” creating vacuum states where it cannot find counterparties to close positions, leading to rapid LP (liquidity provider) losses.

Pool vs. Order Book: Which Architecture Will Win in Leverage Trading?

Strategy 1: Internal Simulation Price (Trade.xyz / Hyperliquid)

When oracle data is disrupted, this approach uses an EMA algorithm based on on-chain trading volume to gradually “drift” the price, maintaining a 24/7 appearance. However, it’s theoretically manipulable as a “shadow market,” risking divergence from actual market prices. Additionally, abnormal high funding rates recorded over weekends have been reported.

Strategy 2: Forced Risk Mitigation (Ostium)

A more practical risk management method. Ostium introduces 0DTE features, automatically forcing the liquidation of positions exceeding leverage thresholds 15 minutes before daily close, reducing maximum intraday leverage from 100x to a safe range. It only allows overnight positions with sufficient margin buffers (5-10%) to handle gaps.

This approach sacrifices some continuity to ensure system safety against Monday gaps and prevents LP pool breaches.

Ostium’s New Paradigm for On-Chain CFDs

Limitations of Initial Projects

Synthetix pioneered bringing real asset prices on-chain, designing an order book-less, infinite liquidity model that greatly addressed liquidity bootstrapping issues. However, lacking active hedging mechanisms at the protocol layer, it couldn’t update prices during trading halts, making it vulnerable to attacks, leading to its retreat from RWA perpetual markets around 2022.

Gains launched a market-making pool model based on oracle prices, introducing GNS tokens as risk buffers, buying back and burning tokens from surplus profits, and issuing new tokens to cover losses. This “oracle + funding pool” model supported large trades but also concentrated risk in the pools and lacked hedging mechanisms.

Ostium’s Innovation: Two-Layer Buffers and Hybrid Risk Management

Launched on Arbitrum mainnet in August 2026, Ostium is a RWA perpetual DEX that deeply understands the adverse game-theoretic relationship where “trader profits = LP losses,” which is long-term unfavorable for LPs.

Its innovation lies in fully separating “settlement” from “market making.” It adopts a two-layer buffer structure:

Layer 1: Liquidity Buffer — Accumulated from protocol revenues, this buffer pays traders’ profits first and absorbs losses.

Layer 2: OLP Vault — Only when the liquidity buffer is exhausted do LPs directly intervene as counterparties.

This architecture allows real-time transfer of unidirectional risks to the global, infinite liquidity market, overcoming the fundamental constraints of traditional models.

Why Choose a Pool Model Over an Order Book?

Ostium’s founders clearly justify maintaining a pool-based approach. Prices of stocks and forex are already perfectly and instantaneously discovered on top-tier exchanges like NASDAQ and CME. Rebuilding an on-chain order book to compete with these “trillion-dollar” institutions in a “limited” environment is resource-wasteful.

Large traders prefer broker models referencing global market prices rather than order books with significant slippage. In the RWA perpetual domain, accessibility and risk management outweigh price discovery.

Transition to a New Market Stage

While RWA perpetual weekly trading volumes exceed $20 billion on some exchanges, weekend volumes drop by 70-90%. This data shows that despite DeFi’s efforts to break free from traditional financial gravity, liquidity still heavily depends on traditional trading hours.

However, innovative projects like Ostium, recognizing the limitations of traditional pool models, are introducing hybrid management (A-Book and B-Book), forced risk mitigation, and two-layer buffers to gradually overcome this “physical time gap.”

Early projects like GMX, which proposed external market maker mechanisms such as the Global Hedge Vault in August 2025 governance forums, indicate a new trend.

Outlook: DeFi’s Challenge to the $80 Trillion Market

The combined 0DTE and global CFD markets total around $80 trillion. This enormous market is driven by retail traders exhausted by the complexity, opacity, and heavy regulation of traditional finance.

DeFi’s innovations—leveraging smart contract transparency, atomic settlement efficiency, and 24/7 access—hold the potential to fundamentally transform the leverage trading landscape. However, solving the “impossible triangle” of asynchronous core attributes with traditional assets remains a key challenge shaping the industry’s future.
