Interchain Queries Relayer

The Interchain Queries (ICQ) Relayer watches for events emitted by the ICQ module. It makes lookups against external chains, and returns query results and proofs such that the ICQ module is able to verify proofs and trigger the appropriate downstream action.

Configuration

The ICQ Relayer configuration is controlled by a single YAML file, the default path of which is $HOME/.icq/config.
