Swim Protocol is a new kind of cross-chain infrastructure powered by Wormhole and designed for an increasingly multi-chain world. Swim’s goal is to provide the tools necessary for users to swap from native assets on one chain to native assets on another, and in doing so reduce the community’s reliance on current bridges and centralized exchanges. Swim eliminates the need for wrapped assets by allowing users to swap from a native asset on one chain to a native asset on any other supported chain, by combining the ideas established by existing stable asset AMMs with Wormhole’s bridging technology to create a new kind of cross-chain liquidity platform. With Swim, users will be able to do this quickly and seamlessly, in a non-custodial fashion. Swim’s elegant solution to the cross-chain asset swap problem minimizes inefficiency, either in the form of wrapped assets, centralized exchanges, or platform-specific native tokens that are used in some cross-chain AMMs. This novel solution is far more capital-efficient than existing approaches and paves the way for a paradigm shift in the way we approach cross-chain interoperability. With Swim, our vision is to create a quick, seamless experience that links between smart contract chains, eventually creating a network of native asset pools on multiple chains through which users can swap seamlessly from one chain to another without having to use wrapped assets or CEXes. With the broader crypto ecosystem rapidly transitioning towards a new, multi-chain paradigm, DeFi applications and liquidity are becoming increasingly scattered across siloed and separate networks. Swim is perfectly positioned to help address this increasing fragmentation and establish itself as a critical piece of infrastructure in the months and years to come. With the rise of BSC, Solana, and others, the community needs a seamless way to bridge native assets.
