Premium Jars were higher-APY fixed jars unlocked by a Sweatcoin Premium subscription (the Sweatcoin app's subscription — not SWEAT MAX). They are a past product: no Premium Jar is currently offered in the app, and new Premium Jars cannot be created or subscribed to.
I had a Premium Jar — what happens to it?
Any still-active Premium Jar keeps working until it unlocks. If your Sweatcoin Premium subscription ended while the Jar was active, its earnings rate was downgraded to a lower rate for the remainder of the lock.
What happens to my Jar after it unlocks?
Nothing changes at unlock — your subscription status has no effect on an unlocked Jar. You can withdraw your $SWEAT as with any other Jar.
Are Premium Jars part of SWEAT MAX?
No. Premium Jars were a Sweatcoin Premium perk, not a SWEAT MAX benefit. SWEAT MAX offers a different jar advantage: a higher Step Jar yield (up to 20% APY vs up to 10% on the free tier).
