DD Tool Package

This is the TS CLI implementation of a tool that would allow to replicate a sequence of TXs

Why

To share DD (e.g. How many emissions this week?)

To share POCs (e.g. How do I repro a potential attack?)

Internals

• Usual TS for Code
• Ganache for Forking and Execution
• Ethers for Encoding and Decoding (human readable side)

How to use

Check /task/steps.json

This is an example of how to get started

The globalLoop would receive a DDSequence to execute

Input and Output mappings are available to create variables

Variables

Variables can be concrete or a stateMapping

Concrete is a real value (e.g your address)

StateMapping is a mapping to the GlobalState

With this system you can store intermediary results or pass hardcoded values

Cheat-like basic implementation

Ganache offers Storage Rewrite and ETH Minting

Some global options in AdditionalSettings allow to use them (MOSTLY TODO)

Architecture

theGlobalLoop is the entire global logic

executeOne is the function that uses ganache, hidden away as it's a low level implementation

Ganache expects ExecutableContracts these are the low level version used internally and returns string/bytes as responses

This means the "Low level" / execution is at the lowest level

The interpretation happens in the loop

Study Guide

Understand theLoop and the types

Once you read these, everything should be more clear
