Resource licensing and escrow
Before you sell or buy a script, you need to understand how FiveM protects code. Some scripts ship open and editable; others ship escrowed, where the core is protected and only a config is exposed. Getting this wrong means buyers cannot make the edits they expected, or sellers ship code they did not mean to give away.
What to understand before you transact
Know open vs escrowed
Open resources ship as readable Lua: fully editable, fully copyable. Escrowed resources protect the core; the buyer edits the exposed config and any files the author left open, but not the protected logic. Neither is "better"; they fit different products.
As a buyer, check editing rights before you buy
If you bought a script specifically to modify its core behavior, an escrowed version will block you. Read the listing: what is configurable, what is open, what is locked. Ask before buying, not after.
