A multi-chain application is a decentralised application that deploys and operates logic across more than one blockchain network simultaneously, rather than being confined to a single chain. It relies on cross-chain communication and interoperability mechanisms, such as bridges or messaging protocols, to synchronise state and move assets between the chains it spans. Multi-chain designs let applications draw on the liquidity, users or specialised capabilities of several ecosystems at once, at the cost of added complexity and cross-chain security risk.
