Hello, tforum users. I know the topic of this post might seem frivolous, but people who know anything about this subject understand the potential benefits involved.

I’ve been looking for any information on writing scripts to dupe items in Roblox games. However, all my attempts at duping items have failed. I hope there are people on this forum who have had more success with this than I have and wouldn’t mind sharing at least a little bit of information. Thanks!

Roblox duping is mostly patched. The old methods (negative quantity, trade window timing, etc.) are dead. The people who can still dupe are using private exploits they don't share.

If you're serious, you need to learn Lua scripting and Roblox's backend architecture. Most dupes now exploit race conditions in the server-client communication, not simple inventory glitches.

I don't do game hacking myself, but if you need help with the scripting side or automating the testing, I can help with Python tools for that.

Are there any guides online or websites where I can find technical information specifically about dupe methods? I have a paid executor for scripts and some experience working with Lua.

Most public dupe guides are outdated. The methods that still work are kept private in small communities. You won't find them on Google.

For Roblox specifically, your best bet is the private exploit forums. V3rmillion was the big one before it went down. Now people are scattered across Discord servers and smaller invite-only sites.

If you already have an executor and know Lua, focus on understanding how Roblox handles inventory transactions between client and server. That's where the race conditions live.

I don't do game hacking, but I build custom scrapers and automation in Python. If you need help testing your scripts at scale or automating the dupe attempts, that I can help with.
