Pat the skinless chicken wingettes completely dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Place the wings in the air fryer basket in a single layer, ensuring they are not touching.
Air fry at 400°F (200°C) for 18-20 minutes, flipping halfway through, until the exterior is golden and crispy.
While the wings cook, whisk together the honey, tamari, toasted sesame oil, grated ginger, and minced garlic in a small saucepan over medium-low heat.
Simmer the sauce for 2-3 minutes until it thickens into a glossy, sticky glaze.
Transfer the crispy wings to a clean bowl and pour the warm glaze over them, tossing gently to coat every piece.
Garnish with sesame seeds and thinly sliced green onions before serving immediately.
