Bitcoin (BTC) Cross-Perpetual Fund-Rate Arbitrage on Boros Reaches All-Time Open Interest Above $200M with 5.98%–11.4% Fixed Yield

COINOTAG News reports that Pendle’s Boros fund-rate trading platform has surpassed $200 million in open interest and logged a cumulative nominal volume exceeding $6.3 billion since its August launch, a span of roughly 4.5 months.

The protocol enables cross perpetual contract fund-rate arbitrage across BTC and ETH markets on Hyperliquid and Binance, with quoted annualized yields from 5.98% to 11.4%. These returns, according to Boros, are several multiples of traditional low-risk strategies such as AAVE lending and ETH staking, while delivering near-zero directional price exposure.

While Boros contends that its arbitrage approach can lock in fixed gains at entry, readers should assess market conditions, liquidity, and platform risk before capital allocation, as with any fund-rate strategy.
