Pat the chicken wings 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 a single layer in an air fryer basket and cook at 400°F for 20-25 minutes, flipping halfway through.
While wings cook, whisk honey, tamari, minced garlic, sesame oil, rice vinegar, and grated ginger in a small saucepan over medium heat.
Simmer the sauce for 3-5 minutes until it thickens into a glossy, sticky glaze.
Transfer the crispy wings to a bowl, pour the warm glaze over them, and toss to coat thoroughly.
Garnish with sesame seeds and sliced green onions before serving.
