Online reports that the official governance page shows that the Frax Finance community has launched a proposal to "introduce USTB as collateral and custody assets for frxUSD", proposing to introduce USTB, Superstate's short-term U.S. government securities fund, as a reserve behind the stablecoin, providing stability, liquidity and Treasury yields. USTB is a tokenized (ERC-20) fund that provides investors with exposure to short-term U.S. Treasury bills. USTB's investment goals are to seek current income consistent with liquidity and principal stability, and target returns consistent with the federal funds rate. The proposal aims to introduce USTB as a collateralized asset with an initial cap of $100 million. Voting has now begun and ends on January 1 next year.
