ICQ Demo

Disclaimer

The following repository and x/interquery module serves as an example and is used to exercise the functionality of Interchain Accounts end-to-end for development purposes only. This module SHOULD NOT be used in production systems

Overview

The following repository contains a basic example of an Interchain Queries module and serves as a developer guide for teams that wish to use interchain queries functionality.

Developer Documentation

Interchain Queries developer docs can be found here

https://github.com/strangelove-ventures/ibc-go/blob/feature/icq_implementation/modules/apps/icq/README.md

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:

    request:
    '@type': /cosmos.bank.v1beta1.QueryAllBalancesRequest
    address: cosmos1ez43ye5qn3q2zwh8uvswppvducwnkq6w6mthgl

        key: null
        limit: "100"
        offset: "0"
        reverse: false
    response:
    '@type': /cosmos.bank.v1beta1.QueryAllBalancesResponse

        denom: stake
    pagination:
        next_key: null
        total: "0"
