By DifiCalc Research Team · Published Sep 20, 2026 Data verified Sep 20, 2026 via DeFiLlama
Tokenized U.S. Treasuries onchain — USDY and OUSG deliver T-bill yield
Best for: Non-U.S. users wanting composable, yield-bearing Treasury exposure with institutional compliance
Risk Assessment
Around $3.4B platform AUM (Allium) led by USDY at roughly $2.1B, audited by Cantina, Zellic, Spearbit and Halborn with a $500K+ bounty and a two-year SEC probe closed without charges in December 2025. Rated A- rather than A because products are permissioned (USDY excludes U.S. persons; OUSG is limited to qualified purchasers), custody is concentrated with regulated partners and the yield mechanically falls when the Fed cuts rates.
Fees
| Management | ~0.25-0.5% annualized issuer and manager fees embedded in NAV |
| Protocol | no mint or redemption fee; network gas only |
