Setup

# Clone this repository and build
git clone https://github.com/cosmos/interchain-accounts.git
cd interchain-accounts
make install 

# Hermes Relayer
[Hermes](https://hermes.informal.systems/) is a Rust implementation of a relayer for the [Inter-Blockchain Communication (IBC)](https://ibcprotocol.org/) protocol.

- Install [Rust](https://www.rust-lang.org/tools/install)
- Install [Hermes](https://hermes.informal.systems/installation.html)

# Bootstrap two local chains & start the relayer with development data
make init

# Wait for the ibc connection & channel handshake to complete and the relayer to start
