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 

#4 Query the trace info for all token denominations

./cronosd q ibc-transfer denom-traces --node https://rpc-t3.cronos.org:443/

#5 Query the denom hash info from a given denom trace

./cronosd q ibc-transfer denom-hash "transfer/channel-1/uatom" <hash>

#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/<app>cli --chain-id $CID
