Overview

STBT is a whitelisted token pegged 1:1 to USD. It is backed mainly by US Treasury bills with maturities under three months, plus smaller positions in tokenized Treasury funds (Superstate USTB and BlackRock BUIDL). Interest is paid to holders daily by rebasing, meaning additional tokens are credited, and the issuing SPV is owned by a purpose trust for bankruptcy remoteness. Access is limited to KYC-verified accredited investors.

US Treasury bills (<3 months), plus small allocations to Superstate USTB, BlackRock BUIDL and USD cash; reverse repo permitted
