Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
Toss the wings in a large bowl with arrowroot powder, sea salt, and black pepper until they are evenly coated.
Place the wings in a single layer in the air fryer basket and cook at 400°F for 20-25 minutes, flipping halfway through until golden brown.
While the wings cook, combine honey, tamari, rice vinegar, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Simmer the sauce for 3-5 minutes until it reduces and thickens into a glossy, sticky glaze.
Transfer the crispy wings to a clean bowl, pour the warm glaze over them, and toss to coat thoroughly.
Garnish the wings with toasted sesame seeds and thinly sliced green onions before serving immediately.
