Demo

Start the two instances of demo chain with following commands

ignite chain serve -c sender.yml --reset-once

ignite chain serve -c receiver.yml --reset-once

Configure and start the relayer

rm -rf ~/.ignite/relayer

ignite relayer configure -a \
--source-rpc "http://localhost:26659" \
--source-faucet "http://localhost:4500" \
--source-port "interquery" \
--source-gasprice "0.0stake" \
--source-gaslimit 5000000 \
--source-prefix "cosmos" \
--source-version "icq-1" \
--target-rpc "http://localhost:26559" \
--target-faucet "http://localhost:4501" \
--target-port "icqhost" \
--target-gasprice "0.0stake" \
--target-gaslimit 300000 \
--target-prefix "cosmos"  \
--target-version "icq-1"

ignite relayer connect

Send the query to "receiver" chain

interchain-query-demod tx interquery send-query-all-balances channel-0 cosmos1ez43ye5qn3q2zwh8uvswppvducwnkq6w6mthgl --chain-id=sender --node=tcp://localhost:26659 --home ~/.sender --from alice

See the result of packet 1

interchain-query-demod query interquery query-state 1 --chain-id=sender --node=tcp://localhost:26659

Output:
