Coinbase USD Stablecoin Yield Fund (CUSHY)
Base: can pause transfers, claw back, gate who may hold, mint, change the code. A single key holds the owner key. A single key, through a contract, can change the code with no delay.
This file replaced an earlier version on 2026-09-24. Superseded to settle the Base freeze power the file had marked unverified: the whole transfer path is now read from verified source, and it has no freeze on Base. Earlier versions.
Subscribers see which of their clients hold this program and whether each household qualifies under these terms, and Ketju emails them when the file changes. $299 per firm per month, first 30 days free.

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 | Form | Exemption claimed | Minimum | Sold to date | Investors |
|---|---|---|---|---|---|
| 2026-06-23 | D | Rule 506(c); Investment Company Act section 3(c)(7) | $100,000 | $25,000,000 | 2 |
Filed by Coinbase Tokenized Stablecoin Yield Feeder Fund Ltd (SEC CIK 2138534). Sold to date counts every sale since the first and does not show the fund’s size today. Ketju reads EDGAR daily and reviews this file again when a new filing appears.
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.
| Agent | SEC file | TA-2 period | Accounts | Issues with master file | Work it hires out |
|---|---|---|---|---|---|
| Superstate Services LLC | 084-06972 | 2025-12-31 | 107 | 0 | None |
Who controls it
Ketju read these powers from the deployed contracts and their verified source code: the token and every contract it checks on a transfer. A power listed here is something the issuer can do; it does not mean the issuer has used it.
| Chain | Freeze a holder | Pause | Claw back | Gate holders | Change the code | Keys held by |
|---|---|---|---|---|---|---|
| Solana | Yes | No | Yes | Yes | No | An account only a program can sign for can freeze a holder and claw back tokens. |
| Base | No | Yes | Yes | Yes | Yes | A single key holds the owner key. A single key, through a contract, can change the code with no delay. |
Who holds the keys
Ketju read every current holder of each power from the chain on 2026-09-24. A single key is one private key, and whoever holds it acts alone. A multisig needs the stated number of signers. A timelock delays every action, so holders can see it before it takes effect.
| Chain | Key | What it can do | Held by | Address |
|---|---|---|---|---|
| Solana | Mint authority | mint new tokens | a single key | 7gF8fi…xAHF |
| Solana | Freeze authority | freeze a holder | an account only a program can sign for | 2Yq4T3…pM7x |
| Solana | Permanent delegate | claw back tokens | an account only a program can sign for | 2Yq4T3…pM7x |

Where it trades
| Venue | Kind |
|---|---|
| Superstate | issuer primary |
Redemption
| Route | Settlement | Settles in |
|---|---|---|
| Redeem with the issuer in its window | Quarterly. Proceeds are paid through Northern Trust, as administrator, on the Redemption Dealing Day for requests received in the previous calendar quarter. One sentence of Superstate’s documentation says liquidity is offered at month end; its fund page and redemption section say quarterly, and we follow them | USD, USDC |
- Coinbase Asset Management or Superstate publishes the offering memorandum; Ketju then reviews the file again for the investor class, the gates, and the redemption terms
- The Solana mint, freeze, or permanent-delegate authority changes, or the Base owner, proxy admin, or implementation changes
- Superstate settles whether redemptions are monthly or quarterly, or the fund gates or delays a redemption
- A Form D amendment changes the minimum, the exemption, or the investor count
Daily checks
Every day Ketju reads each control function in the table above and the contracts the token checks on a transfer. Ketju compares the token’s on-chain supply with yesterday’s, and its market quote with yesterday’s quote, since a fund of this kind accrues a few basis points a day. Ketju also reads every document quoted above and reviews the file again if a quoted passage disappears from its document. Ketju reads EDGAR for the issuer’s Form D filings and the transfer agent’s registration and reviews the file again when a new filing appears. Ketju counts a new, removed, or changed key as a change only when the chain’s own log shows the grant, revocation, or signer change since yesterday. If the log does not show it, Ketju updates the key list in this file and does nothing more. A change opens a review before any client action. Subscribers get an email that names each of their clients who hold the token, with the household result.
