Packet Commitments

Use the query packet commitments command to query the sequence numbers of all packets that have been sent but not yet acknowledged (these are the packets that still have their commitments stored).

USAGE:
    hermes query packet commitments <OPTIONS>

DESCRIPTION:
    Query packet commitments

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

Example

Query ibc-0 for the sequence numbers of packets that still have commitments on ibc-0 and that were sent on transfer port and channel-0:

hermes query packet commitments ibc-0 transfer channel-0

Success: PacketSeqs {
    height: Height {
        revision: 0,
        height: 9154,
    },
    seqs: [
        1,
        2,
        3
    ],
}

Packet Commitment with Sequence

Use the query packet commitment command to query the commitment value of a packet with a given sequence number.

USAGE:
    hermes query packet commitment <OPTIONS>

DESCRIPTION:
    Query packet commitment

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
    sequence                  sequence of packet to query

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

Example

Query ibc-0 for the commitment of packet with sequence 3 sent on transfer port and channel-0:

hermes query packet commitment ibc-0 transfer channel-0 3

Success: "F9458DC7EBEBCD6D18E983FCAB5BD752CC2A74532BBD50B812DB229997739EFC"

Packet Acknowledgments

Use the query packet acknowledgments command to query the sequence numbers of all packets that have been acknowledged.

USAGE:
    hermes query packet acks <OPTIONS>

DESCRIPTION:
    Query packet acknowledgments

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

Example

Query ibc-1 for the sequence numbers of packets acknowledged that were received on transfer port and channel-1:

hermes query packet acks ibc-1 transfer channel-1

Success: PacketSeqs {
    height: Height {
        revision: 1,
        height: 9547,
    },
    seqs: [
        1,
        2,
        3
    ],
}

Packet Acknowledgment with Sequence

Use the query packet acknowledgment command to query the acknowledgment value of a packet with a given sequence number.

USAGE:
    hermes query packet ack <OPTIONS>

    port_id                   identifier of the port to query
    channel_id                identifier of the channel to query
    sequence                  sequence of packet to query

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

Example
