Pending Packets
Use the query packet pending
command to query the sequence numbers of all packets that have not yet been received or acknowledged, at both ends of a channel.
DESCRIPTION:
Output a summary of pending packets in both directions
USAGE:
hermes query packet pending --chain <CHAIN_ID> --port <PORT_ID> --channel <CHANNEL_ID>
OPTIONS:
-h, --help Print help information
REQUIRED:
--chain <CHAIN_ID> Identifier of the chain at one end of the channel
--channel <CHANNEL_ID> Channel identifier on the chain given by <CHAIN_ID> [aliases:
chan]
--port <PORT_ID> Port identifier on the chain given by <CHAIN_ID>
Example
Query the sequence numbers of all packets that either not yet been received or not yet been acknowledged, at both ends of the channel channel-1
.
hermes query packet pending --chain ibc-0 --port transfer --channel channel-1
Success: Summary {
forward: PendingPackets {
unreceived_packets: [
2203,
...
2212,
],
unreceived_acks: [
2183,
...
2202,
],
},
reverse: PendingPackets {
unreceived_packets: [
14,
...
23,
],
unreceived_acks: [
4,
...
13,
],
},
}
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).
DESCRIPTION:
Query packet commitments
USAGE:
hermes query packet commitments --chain <CHAIN_ID> --port <PORT_ID> --channel <CHANNEL_ID>
OPTIONS:
-h, --help Print help information
REQUIRED:
--chain <CHAIN_ID> Identifier of the chain to query
--channel <CHANNEL_ID> Identifier of the channel to query [aliases: chan]
--port <PORT_ID> Identifier of the port 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 --chain ibc-0 --port transfer --channel 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.
DESCRIPTION:
Query packet commitment
USAGE:
hermes query packet commitment [OPTIONS] --chain <CHAIN_ID> --port <PORT_ID> --channel <CHANNEL_ID> --sequence <SEQUENCE>
OPTIONS:
-h, --help Print help information
--height <HEIGHT> Height of the state to query. Leave unspecified for latest height.
REQUIRED:
--chain <CHAIN_ID> Identifier of the chain to query
--channel <CHANNEL_ID> Identifier of the channel to query [aliases: chan]
--port <PORT_ID> Identifier of the port to query
--sequence <SEQUENCE> Sequence of packet to query [aliases: seq]
Example
Query ibc-0
for the commitment of packet with sequence 3
sent on transfer
port and channel-0
:
hermes query packet commitment --chain ibc-0 --port transfer --channel channel-0 --sequence 3
Success: "F9458DC7EBEBCD6D18E983FCAB5BD752CC2A74532BBD50B812DB229997739EFC"
Packet Acknowledgments
Use the query packet acks
command to query the sequence numbers of all packets that have been acknowledged.
DESCRIPTION:
