new on hypersub.xyz: soulbound subscriptions

you can now prevent your hypersub nft from being transferred or sold

great for supply capped hypersubs that want to prohibit secondary sales, for example event passes, curated communities, or sponsorships

so when their subscription ends, what happens to the NFT then

its still theirs, it just doesn't have a balance of time on it

Part B of the question so if I change my image associated with that tier, does that mean any new minted subscriptions have the new piece of art?

yep (and the old ones will too). the image is just an updatable piece of metadata
