Cross-chain protocols, or atomic swaps, allow you to exchange one cryptocurrency for another, even between two different blockchains, without the help from a third party. The most advanced DEXs are now developing cross-chain swaps, and many startups are creating their own solution to this problem. The exchange is able to handle any cryptocurrencies and support atomic swaps between them. It's not enough to support one single network anymore, traders want to be able to trade any assets across multiple blockchains.
