Repo Structure

Each directory at the root of this repository contains code for each individual part that enables this integration:

• bots/: service to automate some steps of the flow which otherwise would required manual intervention from users.
  • Notice: while this is a centralized service, it exists only for convenience. Anyone can fulfill the role of the bots if they wish to do so.
• contracts/: Smart contracts running the arbitration system Learn more.
• dynamic-script/: allows fetching the dynamic content for the arbitration, as described by ERC-1497: Evidence Standard.
• evidence-display/: display interface that should be used to render the evidence for arbitrators, as described by ERC-1497: Evidence Standard.
