Cross-chain refers to the ability of different blockchain networks to communicate and interact with each other. This allows assets or data to be transferred between different blockchains without the need for a centralized exchange.

In the context of cryptocurrency, cross-chain technology enables users to access a wider range of assets and services that may not be available on a single blockchain network. For example, users can trade tokens from one blockchain on another blockchain, or use specific features of a different blockchain without leaving their original network.

By bridging different blockchains, cross-chain technology has the potential to improve liquidity, increase interoperability between networks, and enhance overall functionality in the cryptocurrency space. This can lead to a more seamless and efficient experience for users looking to transact or engage with different blockchain platforms.
