Sell YU where the fixed rate is high, buy it where it is low and hedge both floating legs with perps, and the gap is locked until maturity. Every pair is priced from the live Boros order books at your capital, through two markets or, where Boros lists one, through a single spread market. The pricing follows the CrossEx terminal, which runs the four legs from one Gate account, and its own quote for each pair sits beside ours.
Each Boros leg is taken at the volume-weighted rate of the resting book, AMM included, for the size your capital buys. Boros fees are each market's own taker and settlement fees; perp fees follow the Gate CrossEx schedule for the tier. Capital is Boros initial margin on each leg plus perp margin at the leverage. Perp slippage is not included: CrossEx walks the perp books as well, which is most of the gap between its quote and ours on thin perps such as HYPE. The floating legs cancel only while each perp pays the funding its Boros market tracks, and the books move between reads.
