Double-check if it's actually a promo code for a different game – sometimes people confuse Cloudpunk with Cyberpunk 2077 or other cyberpunk-themed games that do have redemption codes.
Cloudpunk does not have a built-in console or official cheat code entry screen where you can type something like "HOLOCASH5000" to instantly get money. Holocash is earned through completing deliveries, side jobs, and story missions.
I believe you're referring to for the game Cloudpunk , specifically for its in-game currency "Holocash" (the money you earn delivering packages and upgrading your vehicle, the HOVA).
