Invesco Short Duration US Government Securities Fund

USTB represents shares of Invesco Short Duration US Government Securities Fund, which invests in short-term US Treasury bills. The fund was originally offered as Superstate Short Duration US Government Securities Fund; current Superstate documents list the fund under the Invesco name and refer to Invesco's page for the fund summary. The technical identifier of its CoinGecko listing continues to reflect the old name.

According to Superstate's documentation, fund shares can be issued as USTB tokens on Ethereum, Solana and Plume or held in book-entry form with Superstate; book-entry shares can later be converted into tokens. The tokens transfer freely only between wallets added to an allowlist. Subscriptions and redemptions are made by US dollar wire or in USDC at the continuously updated net asset value per share; USDC transactions can also take place outside business days. Interest income is not distributed but is reflected as an increase in net asset value per share.

Participation in Superstate funds is limited to qualified purchasers in supported countries, and a minimum investment amount applies. The token is not a stablecoin but a share in a regulated fund, and its price moves with the unit value. The USTB price shown on Lzzo.com is DefiLlama's US dollar reference and is for information only.
