In a large bowl, toss the wings with baking soda and salt. Place on a wire rack on a baking sheet lined with aluminum foil. Refrigerate for 8 hours.
Grill wings skin side up for 30 to 40 minutes, covered and over indirect heat.
While the wings are grilling, make the sauce. Whisk together butter, Sriracha, honey, soy sauce, lime juice and ginger powder.
Brush the wings with the sauce and cook an additional 5 minutes, covered.
Add the remaining sauce to a large bowl and toss the wings in the sauce. Add the wings to a serving bowl or platter and sprinkle with cilantro before serving.
