Bring a small pot of water to a boil and season with sea salt and black pepper.
Add the shrimp and cook for 2-3 minutes until pink and opaque; drain and immediately plunge into an ice bath to stop the cooking.
Once cooled, peel the shrimp and slice each one in half lengthwise to create two thin pieces.
In a small bowl, whisk together the peanut butter, tamari, rice vinegar, grated ginger, sriracha, and sesame oil until smooth to create the dipping sauce.
Fill a shallow dish with warm water. Submerge one rice paper sheet for about 5-10 seconds until it begins to soften, then lay it flat on a clean work surface.
In the lower third of the rice paper, place 4 shrimp halves (cut side up), followed by a portion of julienned cucumber, shredded carrots, cilantro, and mint.
Carefully fold the bottom of the rice paper over the filling, tuck in the sides, and roll tightly toward the top.
Repeat the process for the remaining three sheets and serve immediately with the peanut dipping sauce.
