Query Channels

Use the query channels command to query the identifiers of all channels on a given chain.

USAGE:
    hermes query channels <OPTIONS>

DESCRIPTION:
    Query the identifiers of all channels on a given chain

POSITIONAL ARGUMENTS:
    chain_id                  identifier of the chain to query

Example

Query all channels on ibc-1:

hermes query channels ibc-1

Success: [
    PortChannelId {
        channel_id: ChannelId(
            "channel-0",
        ),
        port_id: PortId(
            "transfer",
        ),
    },
    PortChannelId {
        channel_id: ChannelId(
            "channel-1",
        ),
        port_id: PortId(
            "transfer",
        ),
    },
]

Query Channel Data

Use the query channel commands to query the information about a specific channel.

USAGE:
    hermes query channel <SUBCOMMAND>

DESCRIPTION:
    Query information about channels

SUBCOMMANDS:
    end        Query channel end
    ends       Query channel ends and underlying connection and client objects

Query the channel end data

Use the query channel end command to query the channel end:

USAGE:
    hermes query channel end <OPTIONS>

DESCRIPTION:
    Query channel end

POSITIONAL ARGUMENTS:
    chain_id                  identifier of the chain to query
    port_id                   identifier of the port to query
    channel_id                identifier of the channel to query

FLAGS:
    -H, --height HEIGHT       height of the state to query

Example

Query the channel end of channel channel-1 on port transfer on ibc-1:

hermes query channel end ibc-1 transfer channel-1

Success: ChannelEnd {
    state: Open,
    ordering: Unordered,
    remote: Counterparty {
        port_id: PortId(
            "transfer",
        ),
        channel_id: Some(
            ChannelId(
                "channel-0",
            ),
        ),
    },
    connection_hops: [
        ConnectionId(
            "connection-1",
        ),
    ],
    version: "ics20-1",
}

Query the channel data for both ends of a channel

Use the query channel ends command to obtain both ends of a channel:

USAGE:
    hermes query channel ends <OPTIONS>

DESCRIPTION:
    Query channel ends and underlying connection and client objects

POSITIONAL ARGUMENTS:
    chain_id                  identifier of the chain to query
    port_id                   identifier of the port to query
    channel_id                identifier of the channel to query

FLAGS:
    -H, --height HEIGHT       height of the state to query
    -v, --verbose             enable verbose output, displaying all details of channels, connections & clients

Example

Query the channel end of channel channel-1 on port transfer on ibc-0:

hermes query channel ends ibc-0 transfer channel-1

Success: ChannelEndsSummary {
    chain_id: ChainId {
        id: "ibc-0",
        version: 0,
    },
    client_id: ClientId(
        "07-tendermint-1",
    ),
    connection_id: ConnectionId(
        "connection-1",
    ),
    channel_id: ChannelId(
        "channel-1",
    ),
    port_id: PortId(
        "transfer",
    ),
    counterparty_chain_id: ChainId {
        id: "ibc-2",
        version: 2,
    },
    counterparty_client_id: ClientId(
        "07-tendermint-1",
    ),
    counterparty_connection_id: ConnectionId(
        "connection-1",
    ),
    counterparty_channel_id: ChannelId(
        "channel-1",
    ),
    counterparty_port_id: PortId(
        "transfer",
    ),
}

Passing the -v flag will additionally print all the details of the channel, connection, and client on both ends.
