Pendle Launches Boros, Letting Traders Bet on Funding Rate Swings for BTC and ETH

Pendle has rolled out Boros, a new platform on Arbitrum that enables traders to take directional bets on the funding rates of Bitcoin (BTC) and Ethereum (ETH) perpetual futures markets — introducing a novel way to hedge or speculate on derivative funding dynamics.

At the heart of the platform are “Yield Units” (YUs) — tradable instruments tied to the realized funding yield of 1 BTC or 1 ETH over a given period. Functionally similar to Pendle’s existing Yield Tokens, YUs give traders the ability to go long if they expect funding rates to rise or short if they anticipate a drop, particularly on centralized exchanges (CEXs) like Binance.

The initial rollout includes capped market limits of $10 million open interest per asset and a 1.2x leverage ceiling, part of a broader focus on risk control and infrastructure testing. Future plans include listing additional assets such as SOL and BNB, as well as integrating platforms like Hyperliquid and Bybit.

For market participants frequently exposed to funding costs — either paying or receiving them on CEXs — Boros provides a clean hedge: short YU when funding is forecasted to drop, long YU when rates are expected to climb.

Liquidity provisioning is also central to Boros’ roadmap. Upcoming Boros Vaults will allow LPs to deposit capital and earn a mix of swap fees, PENDLE token incentives, and carry from favorable rate shifts. These vaults will follow a design similar to Pendle’s fixed-yield model and aim to catalyze early liquidity formation.

To further incentivize growth, PENDLE rewards will be distributed pro rata based on notional traded and order flow, with referral programs and fee rebates slated to launch in the coming weeks.
