Definition ∞ Cross-chain support enables protocols or applications to operate across multiple distinct blockchain networks. This functionality permits the transfer of assets, data, or messages between otherwise isolated blockchain ecosystems. It addresses the inherent interoperability challenges among various chains, facilitating broader utility and liquidity for digital assets. Achieving this often involves specialized bridge protocols or atomic swap technologies.
Context ∞ Discussions around cross-chain support are central to the scalability and usability of the broader digital asset ecosystem, frequently highlighted in news concerning new bridge launches or interoperability solutions. The development of robust and secure cross-chain mechanisms is a key area of innovation for decentralized finance and Web3 applications. Enhancing seamless asset movement between chains remains a significant objective for industry expansion.
