Relay interchain-queries using the new GO v2 Relayer

1. Download and build binaries

cd $HOME
git clone https://github.com/Stride-Labs/interchain-queries.git
cd interchain-queries
go build
sudo mv interchain-queries /usr/local/bin/icq

2. Make home dir for icq and create configurations file

cd $HOME && mkdir .icq
sudo tee $HOME/.icq/config.yaml > /dev/null <<EOF
default_chain: stride-testnet
chains:
  gaia-testnet:
    key: wallet
    chain-id: GAIA
    rpc-addr: http://127.0.0.1:23657      # use your own GAIA RPC endpoint here
    grpc-addr: http://127.0.0.1:23090     # use your own GAIA GRPC endpoint here
    account-prefix: cosmos
    keyring-backend: test
    gas-adjustment: 1.2
    gas-prices: 0.001uatom
    key-directory: /root/.icq/keys
    debug: false
    timeout: 20s
    block-timeout: ""
    output-format: json
    sign-mode: direct
  stride-testnet:
    key: wallet
    chain-id: STRIDE-TESTNET-4
    rpc-addr: http://127.0.0.1:16657      # use your own Stride GRPC endpoint here
    grpc-addr: http://127.0.0.1:16090     # use your own Stride GRPC endpoint here
    account-prefix: stride
    keyring-backend: test
    gas-adjustment: 1.2
    gas-prices: 0.001ustrd
    key-directory: /root/.icq/keys
    debug: false
    timeout: 20s
    block-timeout: ""
    output-format: json
    sign-mode: direct
cl: {}
EOF

3. Import wallets

NOTE: Please use the same wallet you have used for relayer task, as it is the only way to prove that icq runs on your behalf!

icq keys restore --chain stride-testnet wallet
icq keys restore --chain gaia-testnet wallet

4. Create icq service

sudo tee /etc/systemd/system/icqd.service > /dev/null <<EOF
[Unit]
Description=Interchain Query Service
After=network-online.target
[Service]
User=$USER
ExecStart=$(which icq) run --debug
Restart=on-failure
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

5. Start icq service

sudo systemctl daemon-reload
sudo systemctl enable icqd
sudo systemctl restart icqd

6. Check icq logs

journalctl -u icqd -f -o cat

You will have to wait some time until you see some logs (5-15min):
