simd scripts

Boilerplate scripts for boostrapping simd nodes and relayer

Installing simd

Install the simd binary from the ibc-go repository.

git clone git@github.com:cosmos/ibc-go.git && cd ibc-go

make install

Installing Hermes

cargo install ibc-relayer-cli --bin hermes --locked

hermes version # v1.6.0

Setup chains

Bootsrap two simd chains. The following will clear any existing chain state under ./data and create a new environment. It bootstraps two single validator nodes for different simd chains test-1 and test-2.

The scripts create a couple of accounts, both for relayers and demo accounts.

make init

Restore keys using Hermes

Restore keys for relayer wallets rly-1 and rly-2.

make hermes-restore-keys

Setting up IBC transport and relaying.

Create a connection from test-1 to test-2. Note, this also creates ibc clients out of the box.

make hermes-setup-connection

Create an incentivized transfer channel.

make hermes-setup-channel

Start relaying.

make hermes-start
