Fetching Oracle Prices

Create fetchprice Channel

# create channel with clients and connections
# tooks 5 minutes (send any tx to boost)
hermes create channel \
  --a-chain $L2_CHAIN_ID \
  --b-chain $L1_CHAIN_ID \
  --a-port fetchprice \
  --b-port icqhost \
  --new-client-connection 
  
SUCCESS Channel {
    ...
}

Update Chain Params

Create message.json.

Normally the fetch price channel id is channel-1 if you followed the tutorial, else you have to change messages[2][source_channel] to proper channel id.
