Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Pat the chicken wings thoroughly dry with paper towels to ensure they get crispy in the oven.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, leaving space between each piece.
Bake for 35 to 40 minutes, flipping the wings halfway through, until the skin is golden brown and crisp.
While the wings bake, combine honey, coconut aminos, sesame oil, minced garlic, grated ginger, and rice vinegar in a small saucepan over medium heat.
Simmer the sauce for 5 to 7 minutes, stirring occasionally, until it thickens into a glossy glaze.
Transfer the baked wings to a clean bowl, pour the warm glaze over them, and toss until every wing is well coated.
Garnish with sesame seeds and thinly sliced green onions before serving immediately.
