About this Mod
SecureLocks
SecureLocks is a server-side Fabric protection mod for multiplayer servers.
Players can lock containers with a sign, protect villagers from unwanted trading, share access with trusted players, block hopper theft, and keep their storage safe from creepers and other accidental explosions.
Only intentional TNT can break a protected lock, which keeps raiding and risk balanced for survival gameplay.

Server lagging with SecureLocks – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SecureLocks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
