Pendle launches new platform Boros: Targeting a new derivative track for perpetual contract funding rates

Author: Lex, ChainCatcher

On August 6, 2025, the Pendle team, which has taken the lead in the DeFi yield market, expanded its business landscape into a brand new field. They officially launched a platform called Boros on Arbitrum, with a core function that is singular: to transform the uncertain funding rates in perpetual contracts into a standardized, tradable on-chain asset.

In the perpetual contract market, where daily trading volumes often exceed hundreds of billions of dollars, funding rates are a key mechanism for balancing long and short forces. However, their high volatility also exposes traders, market makers, and protocols relying on hedging strategies (such as Ethena) to significant risk.

The birth of Boros is precisely aimed at addressing this long-standing pain point. It provides a dedicated space for market participants to hedge or speculate on the future direction of funding rates. This innovative initiative quickly garnered market response, not only pushing Pendle's total value locked (TVL) to over $8 billion but also causing the price of its native token $PENDLE to rise accordingly.

Core Mechanism of Boros: Taming Funding Rates

In perpetual contract trading, the funding rate is a key mechanism for balancing long and short forces, but its high volatility also brings significant risk exposure to traders. The core goal of Boros is to provide a solution for this uncertainty.

It achieves this by tokenizing future funding rate earnings into Yield Units (YUs). This design is similar to interest rate swaps in traditional finance, allowing both parties to bet on the future trend of rates:

Long (Long YU): Pays a fixed annualized rate (Implied APR) priced by the market in exchange for future actual floating funding rate earnings. Suitable for scenarios where funding rates are expected to rise.

Short (Short YU): Receives a fixed annualized rate while assuming the obligation to pay future floating rates. Suitable for hedging or betting that funding rates will decline.

Boros initially supports Binance's BTC-USDT and ETH-USDT perpetual contracts, with plans to expand to assets like SOL and BNB, as well as platforms like Hyperliquid and Bybit. The entire trading process is completed on Arbitrum's full on-chain order book, ensuring transparency and decentralization.

It is noteworthy that Boros offers capital efficiency. According to official information, the platform supports theoretical capital efficiency of up to 1000 times, allowing users to hedge funding rate risks on large positions with relatively small collateral. This has significant practical value for protocols like Ethena that execute Delta-Neutral strategies and manage large asset scales.

Strategic Considerations: Why Launch Boros Independently?

Pendle chose to establish Boros as an independent platform rather than iterating on the existing V2 framework, reflecting its clear strategic planning.

The original design intention of Pendle V2 was to handle on-chain native yields, and its mechanisms are more suited to relatively predictable yield environments. In contrast, the funding rates of perpetual contracts stem from intense long-short battles within centralized exchanges (CEX), with volatility, frequency, and risk characteristics that are entirely different from on-chain yields.

Starting anew allows Pendle to:

• Customize Risk Management: Tailor risk control models and liquidation engines specifically for high-frequency, high-volatility funding rate trading.
• Isolate Systemic Risk: Avoid directly introducing potential risks from off-chain derivatives into the mature V2 ecosystem.
• Build Focused Liquidity: Create independent liquidity pools and market depth around the specific asset of funding rates.

This decision is a key step for Pendle in expanding its business from "spot yield" to "funding futures," aiming to build a more comprehensive yield trading ecosystem.

Opportunities and Challenges

The market response to Boros in its early launch was strong, with the open interest (OI) being quickly filled and raised multiple times, proving the genuine demand for such tools in the market.

Its greatest opportunity lies in providing urgently needed hedging tools for the large Delta-Neutral strategies in the market (such as Ethena's USDe), effectively managing systemic risks during periods of negative funding rates.

However, the new mechanism also faces challenges. First is systemic risk; the reliance on oracle pricing and built-in leverage may face the risk of cascading liquidations in extreme market conditions. Second is market competition; although Boros is a pioneer in funding rate derivatives, it still needs to contend with potential competition from established derivatives platforms like dYdX and Hyperliquid.

In the future, the success of Boros will depend on the robustness of its risk management, the continued growth of liquidity, and the depth of integration with other protocols in the DeFi ecosystem.

In Conclusion: A New Signal in the Derivatives Market

The launch of Boros can be seen as an important signal in the evolution of the DeFi derivatives market. First, the focus of market innovation is shifting from basic perpetual contracts to more refined "second-order derivatives." The deconstruction and repackaging of core elements such as funding rates and volatility are becoming the new frontier.

Second, there may be clearer functional differentiation in the derivatives space. The future market may consist of comprehensive platforms offering one-stop services and specialized platforms focusing on specific hedging tools (like Boros).

Finally, the demand for new infrastructure is emerging. As funding rate trading matures, tools and services for arbitrage, providing liquidity, and building structured products around it may become the next value growth point in the DeFi ecosystem.
