# Pendle Developer Documentation

> Pendle Finance is a DeFi yield infrastructure protocol. This index covers two products:
> - **Pendle V2**: Yield tokenization — split any yield-bearing asset into PT (fixed yield) and YT (variable yield) for trading
> - **Boros**: Interest rate swap DEX — trade funding rates with leverage on Arbitrum
