Invesco Short Duration US Government Securities Fund (USTB)

This file replaced an earlier record on 2026-09-27. Superseded to add control readings on chains the file listed without one, so a wallet holding the token there matches the file and the daily watch reads it. The terms and the claim model did not change. Superseded records.

Subscribers see which of their clients hold this program, each household’s answer against these terms, and an alert when the file changes. $49 per advisor per month, first 14 days free.

How a holder redeems

USDC paid at once, any day, if liquidity allows. US dollars paid the same day if the request comes before 1pm ET.

“Proceeds are paid as U.S. Dollars to a bank account, or USDC to an Ethereum, Solana, or Plume address. Proceeds are delivered immediately (including non-business days, subject to available liquidity) for payout requests in USDC, or same-day for USD if received before 1pm ET.”

Who keeps the official record

Superstate keeps overlapping records at its NAV agent, in-house, and on chain. It does not say which one is official.

“The assets that back our funds are stored offchain with qualified custodians, and Superstate has overlapping, redundant records of ownership of our funds, including at our fund calculation agent, internally, and on-chain.”

What the issuer says it can freeze or take back

Superstate’s admin address controls minting and the allowlist and can forcibly burn a holder’s tokens.

“Our smart contracts are upgradable and various functions are gated behind the Superstate Admin Address calling them. This includes all minting, adding or removing users from the allowlist, and forcibly burning an investor’s tokens (if required by exogenous legal circumstances, for example).”

What the issuer publishes

Read from the issuer’s own feed at api.superstate.co, as of 2026-09-24. The monitor reads it daily and alerts when the chain shows more tokens than the record states or when the market quote moves away from the published NAV.

• USTB NAV $11.2211 per token.
• USTB: 65,413,837 shares outstanding. 48,843,959 of them are tokens on Ethereum, Solana, Plume Mainnet (74.7%); the rest are held off chain on the transfer agent’s books.

What the issuer filed with the SEC

A private offering files Form D with the SEC within 15 days of its first sale and amends it each year while it sells. The issuer signs it. It states the exemption relied on, the fund’s exclusion from the Investment Company Act (which decides who may buy), the smallest investment accepted, the amount sold, and how many investors hold.

Filed by Invesco Short Duration US Government Securities Fund, a separate series of Superstate Asset Trust (SEC CIK 2004367). Sold to date counts every sale since the first, not the fund’s size today. Ketju reads EDGAR daily; a new filing reopens this file.

The transfer agent’s SEC record

A transfer agent registers with the SEC on Form TA-1 and reports each year on Form TA-2: how many securityholder accounts it keeps and for how many issues it keeps the master securityholder file, the list that says who owns each share.

Who can change the record

Powers read from the deployed contracts and their verified source: the token and every contract it consults on transfer. A power recorded here is the issuer’s ability, not evidence it has been used.

Who holds the keys

Every current holder of each power, read from the chain on 2026-09-27. A single key is one private key: whoever holds it acts alone. A multisig needs the stated number of signers. A timelock makes every action wait, so holders can see it coming.

Where it trades

How it exits

Reopen conditions: events that change an answer above
• The allowlist contract, proxy admin, implementation, or owner on Ethereum changes, or the Solana freeze or permanent-delegate authority changes
• A NAV error, a forced burn, or a missed same-day or immediate redemption
• The Plume contract is read once Plume is graded
• Superstate changes the qualified-purchaser requirement or the $100,000 minimum, or says which of its records governs ownership

What the monitor reads daily

Every control function in the table above and the contracts the token consults on transfer; the token’s on-chain supply against yesterday’s and against the issuer’s published record; and its market quote against the issuer’s published NAV. Every document quoted above is re-read too, and a quote that leaves its document reopens the file. EDGAR is read for the issuer’s Form D filings and the transfer agent’s registration; a new filing reopens the file. A key that appears, disappears, or changes shape counts as a change only when the chain’s own log shows the grant, revocation, or signer change between yesterday’s block and today’s; a difference the log does not show updates this file’s key list and nothing more. A change opens a review item in the governance queue and reopens the file before any client action. Subscribers get an email naming each of their clients who hold it, with the household result.
