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
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]
