IBC wasm relayer

In this tutorial we are using the hermes relayer software. However, feel free to use other relayer software like Hermes and if you want to contribute to the docs by providing the steps for setting up such different software let us know on discord

Setting up hermes relayer

Install hermes from this link

Confgure hermes

Relay traffic

hermes start

Set up a new client, connection and channels

Create ibc clients

hermes create client --host-chain uni-6 --reference-chain nois-testnet-005 --clock-drift 20s
#Note the client id created by this operation (will be needed later on)
hermes create client --host-chain nois-testnet-005 --reference-chain uni-6 --clock-drift 20s
#Note the client id created by this operation (will be needed later on)

Create ibc connection

#07-tendermint-19  is the client id that was generated when creating the client on uni-6
#07-tendermint-14  is the client id that was generated when creating the client on nois-testnet-005
hermes create connection --a-chain nois-1  --a-client 07-tendermint-14  --b-client   07-tendermint-19 

Create transfer channel

#change the xxx with the connection-id on uni-6 point to nois
hermes create channel --a-chain uni-6 --a-connection connection-xxx --a-port transfer  --b-port trasnfer

Create wasm channel

hermes create channel --a-chain uni-6 --a-connection connection-72 --a-port wasm.juno1blablabla(uni proxy address)  --b-port wasm.noisblabla(nois gateway address)  --channel-version nois-v7
