@liskhq/lisk-framework-chain-connector-plugin is a plugin for creating and sending Cross-Chain-Update (CCU) Transactions.
Cross-chain update transactions are the carriers of the information transmitted between chains. By posting a cross-chain update, the receiving chain gets the information required about the advancement of the sending chain. The transaction can also include cross-chain messages and thus serves as an envelope for messages from one chain to another.
$ npm install --save @liskhq/lisk-framework-chain-connector-plugin
