# What's zkJump?

**zkJump is a fast, borderless, multi-chain liquidity bridge that seamlessly exchanges native assets across chains.** 

zkJump utilizes a secure cross-chain bridge network linking blockchains through a highly scalable and technical solution. Our two-way bridge model connects any two chains together through smart contracts and an innovative Witness service to bridge native assets between them without wrapping tokens or swapping them through an intermediary medium.
