Connext

Connext is a modular protocol for securely passing funds and data between chains. Developers can use Connext to build crosschain apps (xApps) - applications that interact with multiple domains (blockchains and/or rollups) simultaneously. Send transactions of value or calldata across chains and/or rollups using Connext. Unlike most other interoperability systems, Connext enables this without introducing any new trust assumptions or external validators. Connext utilizes Watchers, automated offchain actors, that observe the network and halt message passing in the event that fraud or a hack is observed. This ensures that damage due to the failure of any individual part of the network is minimized.
