Generate Keys For Gravity IBC | save as file _ibc-gravity.json_

gravityd keys add ibc-gravity --keyring-backend file --output json     

Generate Keys For Osmosis IBC | save as file _ibc-osmosis.json_

If you have not Node Osmosis, Download first binary

 wget -c https://github.com/osmosis-labs/osmosis/releases/download/v13.1.0/osmosisd-13.1.0-linux-amd64
 mv osmosisd-13.1.0-linux-amd64 osmosisd

Generate Keys

osmosisd keys add ibc-osmosis --keyring-backend file --output json 

Generate Keys For Planq | Save as ibc-planq.json

planqd keys add ibc-planq --keyring-backend file --output json 

Install Hermes

 wget -c https://github.com/informalsystems/ibc-rs/releases/download/v1.1.0/hermes-v1.1.0-x86_64-unknown-linux-gnu.tar.gzb
 tar xvf hermes-v1.1.0-x86_64-unknown-linux-gnu.tar.gz
 mkdir -p ibc-relayer/{bin,conf,systemd}
 mv hermes ibc-relayer/bin/
 mkdir ~/.hermes/{keys,wallets}
