Ooze is a stake-able token that mints you a tradable and upgrade-able NFT that is tied to your Ooze stake.
OOZE can be sacrificed into the Sewer contract to earn 1% daily on your investment. This daily 1% can then be compounded, and more earned through referral rewards, to grow your BALANCE up to a base 8x your DEPOSIT. And you can claim up to 3.65x your BALANCE for a total of a base 29.2x return on your DEPOSIT, not counting any changes in the value of the OOZE token.
Loyalty is rewarded in the factions in the sewer, and you can grow your MAX BALANCE and daily ROI by earning and allocating XP (Xtra Potential) to upgrade your NFT.
