Vault

The vault is a barrel you can find at /warp vault. It used to store your gold, however you are allowed to put your gold in other places. Whenever someone buys something from your sign shop, the gold automatically gets sent to your vault.

If you try to open somebody else's vault you are greeted with this message:

"That's not your vault! Your vault has been highlighted."

After that message is in chat, your vault will have white lines around it.
