Roblox added trade windows with a confirmation screen a long time ago. Both sides see exactly what's being given, and both have to confirm. On paper, trading should be safe now. In practice people get cleaned out every single day, and almost none of it involves "hacking." It's social engineering, and it's the same small set of tricks it's been for a decade. If you can recognize the shape, you can sidestep all of them.
The trust trade
"You send first, I'll send right after." There is no situation where this is necessary. Every game with real trading has a built-in window where both items move at once. The instant someone wants you to "go first" outside that window, the deal is the scam. Not might be. Is.
"I'll add the rest later"
They confirm a lopsided trade in their favor and promise to make up the difference next time, or after they "do one thing." The trade window has already closed. There is no enforcement, no later, and no reason for them to follow through. If a deal is fair, it's fair inside the window. If it's only fair across two trades on a promise, it's not a deal, it's a gift you're giving a stranger.
The fake middleman
For cross-game swaps or anything the trade window can't hold, someone offers a "trusted MM" to hold both sides. The problem isn't that middlemen are always fake. It's that the entire risk lives in the off-platform, hand-it-over step, and a middleman doesn't remove that risk, it just adds a third person who can walk. If a trade can't be done inside a confirmation window, treat it as a donation and decide if you're okay losing it.
Display-name impersonation
Someone sets their display name to match a well-known trader, or a friend, and leans on that borrowed trust. The name floating above a character is not an identity. The @username is. Check the actual username before you believe anyone is who they're performing as.
"Value editor" and free-Robux sites
Anything that asks you to log in to see "real values," generate Robux, or "verify" your account is harvesting logins. There is no generator. There is no editor with secret true prices. We don't link to these and we don't host them, and you should close the tab the moment one asks for a password. Real value lists, ours included, never need your account.
The downgrade dressed as an upgrade
A "helper" offers to upgrade your pet, awaken your fruit, or boost your item if you just hand it over for a second. You hand it over. There is no second. This one preys on people who don't know a mechanic, so the defense is simple: no legitimate upgrade in any of these games requires giving your item to another player first.

Read those again and notice they're all the same move. Every one asks you to step outside the protection the platform already built for you — the trade window, the confirm screen, the on-platform record — and replace it with trust in a person you don't know. That's the tell, and it's also the rule that kills the entire list: if a deal only works when you go first or go off-platform, it isn't a deal. Knowing your values protects you from bad trades. Knowing that one rule protects you from the people trying to make sure no trade happens at all.
