Pendle Finance has officially launched Boros on Arbitrum, a groundbreaking protocol that introduces on-chain trading of perpetual funding rate exposure. Designed to complement Pendle’s existing yield-tokenization infrastructure, Boros enables traders to speculate on or hedge against funding rate volatility in major crypto markets. The launch brings a new class of financial instrument to DeFi: Yield Units (YUs), which represent the realized yield on one unit of notional exposure, starting with Bitcoin and Ethereum perpetuals.
Boros launches with two primary markets: BTC and ETH funding rates, both sourced from Binance perpetual contracts. Each market has an initial open interest cap of $10 million and allows a maximum leverage of 1.2x. These conservative parameters reflect Pendle’s focus on stability and risk management during the platform’s early growth phase. Future integrations with exchanges such as Bybit and Hyperliquid, as well as additional assets like SOL and BNB, are already in the roadmap.
Yield Trading for the Next Era
Unlike traditional derivatives platforms that embed funding rate costs into positions, Boros allows users to isolate and trade funding rate exposure directly. This offers DeFi traders a novel way to express macro views or execute precise hedges without taking directional price risk on the underlying asset. Whether a trader anticipates rising or falling funding rates, Boros provides the infrastructure to execute those views with high capital efficiency.
The launch also introduces Boros Vaults for liquidity providers. LPs can earn swap fees, receive PENDLE token incentives, and benefit from favorable changes in implied APRs. These vaults are optimized for passive yield generation, making them an attractive option for users looking to earn returns from market activity without active management. An incentive program and referral system are set to roll out in the coming weeks, further boosting LP engagement.
Strong Ecosystem Momentum Ahead of Launch
The debut of Boros comes at a time of rapid growth for Pendle. In late July 2025, the protocol reached a new all-time high total value locked (TVL) of $7.02 billion. This surge was driven by market anticipation for Boros, along with strategic plans involving HyperEVM and Converge—Pendle’s upcoming ecosystem expansions. In April, the protocol reported that 37% of the circulating PENDLE supply—over 61 million tokens—was locked with an average duration of 1.31 years, reflecting deep DAO alignment.
Boros does not introduce a new token; instead, it builds on the existing PENDLE and vePENDLE framework. This ensures that value continues to accrue to current token holders and avoids the dilution concerns common with new protocol launches.
As Pendle continues to pioneer in the realm of on-chain yield and derivatives, Boros marks a significant milestone in bringing more complex financial primitives to DeFi. With robust design principles, risk-aware parameters, and strong community engagement, Boros positions Pendle at the forefront of yield-based innovation in Web3 finance.
