Is FiveM escrow safe?

Two different questions hide inside "is escrow safe." The first is whether the mechanism is trustworthy: it is. Cfx asset escrow is operated by the platform owner, delivered through Tebex, and bound to the buyer's Cfx account via the keymaster system, which is why an escrowed resource cannot be handed around like a zip file. Nobody outside Cfx's pipeline is encrypting your resource, and nobody outside your licence can run it.

The second question is whether the code you can't read is safe to run on a server with real players and a real economy, and escrow answers nothing about that. An escrowed net event handler can trust the client's money amount just as easily as an open one; escrow simply removes your ability to check. That is why the useful safety questions are about the seller: do they publish an exact file-level list of what ships open and what ships locked, a dated changelog, a measured performance figure with method and date, and a written support commitment?

In practice a safe escrowed purchase looks like this: the config, locales, framework bridge, and exports ship as readable source; only core logic is locked; the listing names the framework versions actually tested; and the resource goes onto a staging server before production, where you run the same restart, load, and client-trust checks you would run on anything else. Escrow changes what you can read. It should never change what you test.
