Soak bamboo skewers in water for 20 minutes to prevent combustion during grilling.
In a medium mixing bowl, whisk together mayonnaise, sweet chili sauce, Sriracha, honey, minced garlic, grated ginger, and smoked paprika until emulsified.
Remove 1/4 cup of the sauce mixture and set aside in a refrigerated container for final glazing.
Season the chicken cubes with salt and black pepper in a large bowl, then incorporate the remaining sauce mixture to coat all surfaces.
Allow the chicken to marinate for a minimum of 15 minutes at room temperature.
Preheat a grill or heavy-bottomed grill pan to medium-high heat (approximately 400°F/204°C) and lightly coat with high-smoke-point oil.
Thread 5 to 6 chicken cubes onto each skewer, ensuring they are not overly compressed to allow even heat distribution.
Grill the skewers for 5 to 6 minutes per side, or until the internal temperature reaches 165°F (74°C) and the exterior shows maillard reaction charring.
Remove skewers from heat, drizzle with the reserved sauce, and garnish with sliced green onions and sesame seeds.
