Who may buy, hold, transfer, and redeem

A unit of the ULTRA sub-fund, with the rights the Delta Master Trust deed gives unitholders.
“Investors are unitholders of ULTRA and are entitled to the rights set out in the trust deed”

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 |
|---|---|---|---|---|---|
| 2025-11-03 | D/A | Rule 506(c); Investment Company Act section 3(c)(7) | $200,000 | $135,341,364 | 7 |
| 2024-11-06 | D | Rule 506(c); Investment Company Act section 3(c)(7) | $200,000 | $0 | 0 |
Filed by Delta Wellington Ultra Short Treasury On-Chain Fund, a sub-fund of the Delta Master Trust (SEC CIK 2043109). 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.
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.
| Chain | Freeze a holder | Pause | Claw back | Gate holders | Change the code | Keys held by |
|---|---|---|---|---|---|---|
| Ethereum | No | No | Yes | Yes | Yes | Admin key: a single key. |
| Arbitrum | No | No | Yes | Yes | Yes | Admin key: a single key. |
Who holds the keys
Every current holder of each power, read from the chain on 2026-09-24. 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.
| Chain | Key | What it can do | Held by | Address |
|---|---|---|---|---|
| Ethereum | Admin role | grant and revoke these powers, decide who may hold | a single key | 0x3d5d…35bc |
| Arbitrum | Admin role | grant and revoke these powers, decide who may hold | a single key | 0x3d5d…35bc |

Where it trades
| Venue | Kind |
|---|---|
| Libeara Delta platform (FundBridge onboarding) | issuer primary |
How it exits
| Path | Settlement | Settles in |
|---|---|---|
| Redeem with the issuer in its window | Daily redemptions to the manager on trading days, settled in one to two business days; the holder sends units to the fund’s contract and receives USDC through the fund’s on- and off-ramp provider or US dollars by wire | USDC, USD |
- FundBridge or Libeara publishes the information memorandum, trust deed, or contract addresses; the file is then re-read for the record, the investor class, and the Solana and Avalanche contracts
- The DEFAULT_ADMIN_ROLE, SUPER_ADMIN, or OPERATOR_ADMIN holder or the implementation of ULTRA on Ethereum or Arbitrum changes, or the transfer limit rises above zero
- The Solana mint, which rwa.xyz shows holding most units, is identified from an issuer source; it is then read and added
- A new Form D or amendment for CIK 2043109 changes the exemption, the exclusion, or the minimum
- The fund suspends or delays a redemption past two business days
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 its market quote against yesterday’s quote, since a fund of this kind accrues a few basis points a day. 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; a new filing reopens the file. A change opens a review item in the governance queue and reopens the file before any client action.
