USD0++ is a liquid staking version of the USD0 stablecoin backed by T-bills from RWA entities like Hashnote, Ondo, and BlackRock, functioning as a liquid savings account with a 4-year USD0 lock-up. It offers rewards while remaining transferable, with $USUAL incentives promoting the growth and adoption of USD0. The DAO allows for 1:1 early redemption particularly against USUAL tokens.
