The command called “splice” can take a json payload or a ‘splice script’, process it into a list of ‘actions’ and then execute those actions. These actions include or will include everything you would want to do with a splice: * Splice into a channel * Splice out of a channel * Fund from wallet * Deposit to wallet * Send funds to bitcoin address Changelog-Added: A new magic “splice” command is added that can take a ‘splice script’ or json payload and perform any complex splice across multiple channels merging the result into a single transaction. Some features are disabled and will be added in time.
