Cross-chain swaps are revolutionizing decentralized finance (DeFi) by enabling seamless asset transfers across diverse blockchain networks. These protocols enhance liquidity, reduce fees, and unlock multi-chain trading opportunities. Here, we analyze the top 10 cross-chain swap solutions, their features, and use cases to optimize your DeFi experience.
What Is a Cross-Chain Bridge in DeFi?
A cross-chain bridge facilitates interoperability between blockchains, allowing users to transfer assets or interact with decentralized applications (dApps) across platforms. These bridges are pivotal for DeFi’s growth, as they connect fragmented ecosystems, boost liquidity, and expand accessibility.
