Place chicken wings in a large mixing bowl. Cover with chicken broth. Cover the bowl with plastic wrap and refrigerate. Allow wings to brine for at least 1 hour and up to overnight.
Preheat oven to 425 degrees. Line a baking sheet with aluminum foil. Arrange chicken wings in a single layer on the baking sheet. Bake 55 minutes.
Whisk soy sauce, brown sugar, ginger, garlic, honey, sesame oil and rice vinegar in a saucepan over medium heat. Bring to a boil, whisking constantly.
Lower the heat. Combine cornstarch and 3 Tbsp. of water in a small bowl. This is a slurry. Pour the slurry into the sauce and whisk to combine. Simmer the sauce until thickened.
Melt the butter over medium heat in a large nonstick pan. Put the wings into the pan. Toss in the butter until golden brown, 3-4 minutes. Add the sauce and toss the wings in the sauce.
Remove from heat. Transfer wings to a serving plate. Garnish with sesame seeds.
