# Common IBC Commands Nodes can use the Inter-Blockchain Communication Protocol (IBC) command with cronosd. Here are the commonly used IBC commands on Cronos Chain: **#1 Querying commands for the IBC module on Cronos** ``` ./cronosd q ibc ``` Subcommands: * channel: IBC channel query subcommands * client: IBC client query subcommands * connection: IBC connection query subcommands ``` ./cronosd query ibc channel ``` **#2 Querying command to see all channels with the node on Cronos** ``` ./cronosd q ibc channel channels ``` Example: ``` ./cronosd q ibc channel channels --node https://rpc-t3.cronos.org:443/ ``` Expected output: ``` Channels: - channel_id: channel-0 connection_hops: - connection-0 counterparty: channel_id: channel-131 port_id: transfer ordering: ORDER_UNORDERED port_id: transfer state: STATE_OPEN version: ics20-1 ``` **#3 Querying command to find the specific blockchain channel** ``` ./cronosd q ibc channel client-state transfer channel-number ``` Example: ``` ./cronosd q ibc channel client-state transfer channel-207 ``` \ \ \&#xNAN;**#4 Query the trace info for all token denominations** ``` ./cronosd q ibc-transfer denom-traces --node https://rpc-t3.cronos.org:443/ ``` \ \&#xNAN;**#5 Query the denom hash info from a given denom trace** ``` ./cronosd q ibc-transfer denom-hash "transfer/channel-1/uatom" ``` **#6 Query the contract addresses connected with the coin denom** ``` ./cronosd query cronos contract-by-denom [denom] [flags] ``` **#7 Create a new IBC client with the specified client state and consensus state** 
./cronosd tx ibc client create [path/to/client_state.json] [path/to/consensus_state.json] [flags]
Example: ``` ./cronosd tx ibc client create [path/to/client_state.json] [path/to/consensus_state.json] --from node0 --home ../node0/cli --chain-id $CID ``` **#8 Query all channels associated with a connection** ``` ./cronosd query ibc channel connections [connection-id] ``` Example: ``` ./cronosd query ibc channel connections [connection-id] --count_total ``` **#9 Query a channel end** ``` ./cronosd query ibc channel end [port-id] [channel-id] [flags] ``` **#10 Query a next receive sequence** ``` ./cronosd query ibc channel next-sequence-receive [port-id] [channel-id] [flags] ``` **#11 Query a packet acknowledgment** ``` ./cronosd query ibc channel packet-ack [port-id] [channel-id] [sequence] [flags] ``` **#12 Query a packet commitment** ``` ./cronosd query ibc channel packet-commitment [port-id] [channel-id] [sequence] [flags] ``` **#13 Query all packet commitments associated with a channel** ``` ./cronosd query ibc channel packet-commitments [port-id] [channel-id] [flags] ``` **#14 Query a packet receipt** ``` ./cronosd query ibc channel packet-receipt [port-id] [channel-id] [sequence] [flags] ``` **#15 Query all the unreceived acks associated with a channel** ``` ./cronosd query ibc channel unreceived-acks [port-id] [channel-id] [flags] ``` **#16 Query all the unreceived packets associated with a channel** ``` ./cronosd query ibc channel unreceived-packets [port-id] [channel-id] [flags] ``` **#17 Query the consensus state of a client at a given height** ``` ./cronosd query ibc client consensus-state [client-id] [height] [flags] ``` **#18 Query the heights of all consensus states of a client** ``` ./cronosd query ibc client consensus-state-heights [client-id] [flags] ``` **#19 Query all the consensus states of a client** ``` ./cronosd query ibc client consensus-states [client-id] [flags] ``` **#20 Query the latest header of the running chain** ``` ./cronosd query ibc client header ``` **#21 Query the current ibc client parameters** ``` ./cronosd query ibc client params ``` **#22 Query the self-consensus state for this chain** ``` ./cronosd query ibc client self-consensus-state ``` **#23 Query all available light clients** ``` ./cronosd query ibc client states ``` **#24 Query client status** ``` ./cronosd query ibc client statue [client-id] [flags] ``` **#25 Query all connections** ``` ./cronosd query ibc connection connections ``` **#26 Query stored connection end** ``` ./cronosd query ibc connection end [connection-id] [flags] ``` **#27 Query the current IBC connection parameters** ``` ./cronosd query ibc connection params ``` **#28 Query stored client connection paths** ``` ./cronosd query ibc connection path [client-id] [flags] ``` **#29 Query the denom trace info from a given trace hash or IBC denom** ``` ./cronosd query ibc-transfer denom-trace [hash/denom] [flags] ``` Example: ``` ./cronosd query ibc-transfer denom-trace 27A6394C3F9FF9C9DCF5DFFADF9BB5FE9A37C7E92B006199894CF1824DF9AC7C ``` **#30 Get the escrow address for a channel** ``` ./cronosd query ibc-transfer escrow-address [port] [channel-id] [flags] ``` **#31 Query the current IBC-transfer parameters** ``` ./cronosd query ibc-transfer params ``` **#32 Query the total amount of tokens in escrow for a denom** ``` ./cronosd query ibc-transfer total-escrow [denom] [flags] ``` **#33 Query the IBC-fee enabled status of a channel** ``` ./cronosd query ibc-fee channel [port-id] [channel-id] [flags] ``` **#34 Query the IBC-fee enabled channels** ``` ./cronosd query ibc-fee channels ``` **#35 Query the relayer counterparty payee on a given channel** ``` ./cronosd query ibc-fee counterparty-payee [channel-id] [relayer] [flags] ``` Example: ``` ./cronosd query ibc-fee counterparty-payee channel-5 cosmos1layxcsmyye0dc0har9sdfzwckaz8sjwlfsj8zs ``` **#36 Query for an unrelayed incentivized packet by port-id, channel-id and packet sequence** ``` ./cronosd query ibc-fee packet [port-id] [channel-id] [sequence] [flags] ``` **#37 Query for all of the unrelayed incentivized packets and associated fees across all channels** ``` ./cronosd query ibc-fee packets ``` **#38 Query for all of the unrelayed incentivized packets on a given channel** ``` ./cronosd query ibc-fee packets-for-channel [port-id] [channel-id] [flags] ``` **#39 Query the relayer payee address on a given channel** ``` ./cronosd query ibc-fee payee [channel-id] [relayer] [flags] ``` Example: ``` ./cronosd query ibc-fee payee channel-5 cosmos1layxcsmyye0dc0har9sdfzwckaz8sjwlfsj8zs ``` **#40 Query the total acknowledgment fees for a packet** ``` ./cronosd query ibc-fee total-ack-fees [port-id] [channel-id] [sequence] [flags] ``` Example: ``` ./cronosd query ibc-fee total-ack-fees transfer channel-5 100 ``` **#41 Query the total receive fees for a packet** ``` ./cronosd query ibc-fee total-recv-fees [port-id] [channel-id] [sequence] [flags] ``` **#42 Query the total timeout fees for a packet** ``` ./cronosd query ibc-fee total-timeout-fees [port-id] [channel-id] [sequence] [flags] ``` \ \\
