This workshop is a guided hands-on session for cross-blockchain application development on top of atomic-swaps. For the execution of the atomic swap we will use C( )MIT, an open source protocol enabling the trustless exchange of digital assets (https://github.com/comit-network/comit-rs).

The workshop will first introduce you to C( )MIT’s Hello-World example. We will then extend the simple example together to build a simple DEX.

Rough agenda:
• Hello-World example, which steps you through an atomic swap of Bitcoin to Ether using C( )MIT;
• Introduction to the C( )MIT API;
• Build a simple DEX on top of C( )MIT using Typescript;

The main coding language of the workshop is Typescript. However, anybody with coding experience is welcome to join.

Requirements for participants:
Bring your own laptop and have installed:
• Docker-compose
• node-js 10+
• yarn (recommended)
• Linux/Mac recommended
