Ren (REN) is an open protocol that aims to bring interoperability and liquidity to various blockchain platforms.Ren is a sophisticated platform with several use cases, but it is ultimately intended to help DeFi initiatives overcome entrance and funding constraints. It allows DeFi projects to include foreign cryptocurrency assets like Bitcoin (BTC) and Zcash (ZEC) in their offers as a plug-in. Users may effectively exchange any token between any two blockchains without the need for intermediaries such as "wrapped" versions of tokens, such as Wrapped Bitcoin (WBTC) and Wrapped Ethereum (WE) (WETH).
