Explosion-Proof Chests
This is an incredibly basic mod that makes all block entities (that is, blocks that store data like items) unable to be blown up.
This mod has been tested on 1.18.2-1.21.8. It likely works on lower versions but may need to be recompiled with a lower mixin Java compatibility version. I have no interest in supporting ancient versions, however.
This mod is good for SMPs where you don't want people stealing other people's items - I made it specifically to go alongside Hey That's Mine, since it only prevents players from opening chests, not other forms of theft.
