Introduction to Boros

Pendle Boros is an on-chain platform for trading interest rate swaps. The protocol enables users to take long or short positions on variable interest rates with leverage through a hybrid system combining a central limit order book and AMM. At launch, Boros only support trading of funding rates, though Boros is designed to allow trading of any types of interest rates that have an index oracle.

Boros is deployed on Arbitrum and the addresses can be found here.
