## What is the current behavior?

<!-- Please describe the current behavior that you are modifying,

Resolves #1019 


Context:
- `get_eoa` is in kakarot.py file
- kakarot.py file uses toml package
- deploy_kakarot.py uses get_eoa
- toml is called in the deployer docker image
- toml is a dev dep, and is not available in the docker image
- fail ⚠️

Solutions:
- split kakarot.py in order to not try to import toml for the following
functions: `get_eoa` and the ones it uses (~5 in the same file) =>
cleaner but overkill for 1 dependency
- add toml as real dependency => quick and dirty but fast
