Place the lime rind and juice, sriracha, oil, salt and pepper in a large bowl and mix to combine. Reserve 1¼ tablespoons of the marinade and set aside.
Add the chicken to the bowl and toss to combine. Cover and refrigerate for 15 minutes to marinate. Preheat a char-grill pan over medium heat. Thread the chicken onto 8 metal skewers, brush the chicken with the extra oil and cook, in batches, for 4–5 minutes each side or until charred and cooked through.
Put the reserved marinade and mayonnaise in a small bowl and stir to combine. Serve the skewers with the sriracha mayonnaise, coriander leaves, lime wedges and extra sriracha.
