Hermes IBC Workshop

Introduction

In this workshop we will be working with the Hermes IBC Relayer in order to transfer fungible tokens (ics-020) between two Starport custom Cosmos SDK chains.

This repository contains all the instructions if you want to run the workshop in your local computer. Please follow the step-by-step instructions below to complete the workshop.

This workshop's primary goal is to better understand the IBC protocol and how packets are relayed from one chain to another using the IBC primitives (client, connections, channels, ports, and packets).

This workshop was presented at the HackAtom RU by Andy Nogueira from Informal Systems. Please check the presentations folder for the slides.

You can also watch the English recording on YouTube
