How to tell if a FiveM script is secure against exploits

Short answer: a FiveM script is hard to exploit when the server decides everything: it checks distance, money, permissions and cooldowns on every action, rolls rewards on the server, locks payouts against double requests and never trusts values sent by the client or the interface. Before buying, look for these points in the description or ask the developer directly.

Why client trust is the main risk

Cheaters can trigger any client event and send any value to the server. If a script lets the client say "give me this reward" or "this item costs 0", it will be abused. Many money and item duplication exploits come from scripts that trust the client.

Checklist for a secure script

Server-side validation. Every action is checked on the server: is the player near the location, do they have the money, the job or the permission?

Server-side randomness. Rewards and chances are rolled on the server, never in the client or the interface.

Locks against double requests. Double clicks and parallel requests must never pay out twice.

Correct order. Money is taken before an item changes hands, and items are stored before they are removed elsewhere. If a step fails, everything is rolled back.

Secrets on the server. Discord webhooks and similar secrets belong in a server-only config, not in a file the client downloads.

Logs. Important actions are logged, so staff can see what happened.

How Goliath Scripts handles it

Every Goliath script follows the same rule: the interface only sends what the player wants to do, the server decides what happens. Distance, money and permissions are checked on every action, rewards are rolled on the server, double clicks are locked per player and webhooks live in a server-only config.

Questions

Does escrow make a script secure?

No. Escrow protects the code from being copied, it does not fix insecure logic. A script is secure because of its server checks.

How can I test a script myself?

Trigger its events from a test client with wrong values, from far away or many times in a row. A secure script rejects all of it.
