+ * The aim of this implementation of the {@link InteractionsLoader} is to make use of Redstone Gateway endpoint
+ * and retrieve contracts' interactions. Optionally - it is possible to pass skipOrphans flag in the constructor
+ * and therefore receive only these transactions which are confirmed. To learn more about Redstone Gateway please visit
+ * {@link https://github.com/redstone-finance/redstone-sw-gateway}.
+ * Please note that currently caching is switched off for RedstoneGatewayInteractionsLoader due to the issue mentioned in the
+ * following comment {@link https://github.com/redstone-finance/redstone-smartcontracts/pull/62#issuecomment-995249264}
