Leave the shells on the shrimp but make a single cut along the back of the shell with kitchen scissors. Use a paring knife to devein the shrimp. Set aside.
Heat the oil in a large skillet over medium-high heat until hot and shimmering. Add the green onions, garlic, ginger, salt, and a few grinds of pepper and cook until the aromatics are toasty (but don't burn the garlic), 1 minute.
Add the shrimp and sauté until the shrimp are just cooked through, 3 or 4 minutes. Add the peanuts and cook, stirring, so that they get toasty, 1 minute. Add the spice mix, coriander, sriracha, and hot sauce. Add the butter and stir to make a glaze. Stir in the cilantro and mint. Remove from the heat and squeeze over the lime juice. Adjust the salt to taste. Transfer to a platter and serve immediately.
