The Edenic covenant was a covenant of sustaining the garden in Eden and maintaing it’s organic status:

Genesis 2:15 (NKJV):

15 Then the Lord God took the man and put him in the garden of Eden to tend and keep it.

The Edenic covenant which God made with man was the type of covenant where God commanded Adam to tend (to take care of, to farm, to download the spiritual identity of God’s will from Heaven and impart it into the garden in Eden, to pray over, to maintain the domestic or organic status of the animals, to sustain the organic status of the trees, plants, and all the living animism in the garden),

And to also keep it, (conduct the Garden of Eden as a business).
