In a small saucepan combine the Sweetened Condensed Coconut Milk, lime juice, eggs and cornstarch. Mix thoroughly.
Add vegan butter, and cook over low heat, whisking continuously until first bubble appears on surface, and mixture is thick enough to hold marks from the whisk, about 6-8 minutes.
Pour mixture into the graham cracker crust. Cover with plastic and refrigerate at least 5 hours, preferably overnight.
Serve with whipped topping.
