Roblox RemoteEvent Security Checklist
RemoteEvents are powerful because they connect the player’s client to server code. Treat every RemoteEvent like public input.
Never trust client values
- The client can request an action, but the server should calculate rewards, prices, cooldowns and ownership.
- Validate item IDs, upgrade names, map zones and target objects against server-owned tables.
- Reject impossible numbers, unexpected types, missing player state and values outside config limits.
Add rate limits and cooldowns
- Use per-player cooldown tables for clicks, purchases, teleports and reward claims.
- Do not let spammed RemoteEvents create unlimited currency, duplicate items or bypass timing.
- Return clear feedback to the client without revealing private server logic.
Test like a hostile client exists
- Call the RemoteEvent with wrong argument types, very large numbers and invalid item names.
- Test players who do not own a game pass, lack enough currency or have not unlocked the zone.
- Check that DataStore saves only after server-approved state changes.
