USTB Fund
Superstate Short Duration U.S. Government Securities Fund (USTB) is a private fund tokenized on the Ethereum blockchain. It is designed to provide eligible investors with access to short-duration U.S. Treasury Bills and U.S. Government Agency securities, aiming for yields aligned with the federal funds rate [1] [2].
Overview
The Superstate Short Duration U.S. Government Securities Fund (USTB) operates as a tokenized investment product focusing on U.S. government debt. It is structured as a private fund and is primarily accessible to U.S. Qualified Purchasers and U.S. Accredited Investors [2]. The fund's investment strategy involves holding short-duration U.S. Treasury and U.S. Agency securities. The objective is to target returns that correspond with the federal funds rate [1]. The fund calculates a daily Net Asset Value (NAV) [2].
USTB represents an effort to bridge traditional financial assets with blockchain technology. By tokenizing the fund's shares, Superstate aims to enable on-chain ownership, transfer, and compliance for eligible investors. The fund's structure incorporates established service providers from both traditional finance and the digital asset space [3].
Technology
USTB is tokenized on the Ethereum blockchain, utilizing the ERC-20 token standard [1] [2]. The fund's operation incorporates an Ethereum-based Allowlist mechanism. This Allowlist is designed to manage on-chain ownership, facilitate token transfers, and ensure compliance with relevant regulations [3].
In addition to Ethereum, USTB tokens are also present on the Plume Network and are tracked as Off-Chain (Book-Entry) holdings [2]. The use of blockchain technology is intended to potentially enable features like peer-to-peer transactions among eligible participants in the future, subject to applicable restrictions [3].
Underlying Assets
The Superstate Short Duration U.S. Government Securities Fund invests in a portfolio of short-duration U.S. Treasury Bills and U.S. Government Agency securities [1] [3]. These are debt obligations issued or guaranteed by the U.S. government or its agencies. The fund's investment strategy is focused on short-duration instruments, which typically have maturities of one year or less for Treasury Bills and varying short-term durations for Agency securities. The fund aims to generate yield that corresponds to the prevailing federal funds rate [1].
