//interface for parent contract of any child token

/*
- Parent contract interface for adding custom logic before calling the 'transfer' function 
in the ERC721/ERC20 child chain contract on the Matic chain
- 'transfer' executes the 'beforeTransfer' of this interface contract
- It must follow this interface and return a bool value and 
- in case of ERC20 contracts, it should not have 'require' statements and instead return 'false'
- IParentToken contract address in childchain contract can be updated by owner set in rootchain contract only

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

• Separate big codebases into multiple repositories.

-- Remove the history from 
rm -rf .git

-- recreate the repos from the current content only
git init
git add .
git commit -m "Initial commit"

-- push to the github remote repos ensuring you overwrite history
git remote add origin [email protected]:<YOUR ACCOUNT>/<YOUR REPOS>.git
