USDtb (Anchorage Digital Bank)

What the client owns
A dollar stablecoin that Anchorage Digital Bank alone owes, at $1, and only to its own clients; the reserve behind it is 99% BlackRock BUIDL, but the holder owns no BUIDL share and earns none of its income. Issuer liability: The issuer’s promise to pay a fixed amount; the holder owns no share of the reserve behind it.
Who may hold it
US retail investors. First purchase minimum not stated. State coverage not confirmed by the issuer. Two groups, two sets of terms. Anyone may hold USDtb and send it to another wallet, unless the bank has blocked the wallet or the person is in a prohibited jurisdiction or under sanctions; no KYC is needed to hold it. Only the bank’s clients may buy it from the bank or sell it back, and the bank onboards them under its Master Account Agreement; Anchorage’s pages speak to institutions, and no document read says it opens accounts for individuals. The bank publishes no minimum and keeps its fee schedule private. USDtb is registered with no securities regulator and has no Form D: Anchorage calls it a payment stablecoin and drafts its terms to the GENIUS Act. That Act says a permitted issuer’s payment stablecoin is not a security, but it takes effect only on the earlier of 18 January 2027 or 120 days after the regulators’ final rules, and no document read shows the OCC has approved the bank as a permitted issuer. The file therefore records the path as other, not as “not a security”. The claim is the bank’s promise to pay $1. A transfer passes it with the token, and the terms name no register of holders other than the chain. The holder owns no share of the reserve. Upstream, the reserve’s BUIDL sits in Anchorage wallets on Solana, BNB Chain, and Avalanche. BUIDL’s own file (blackrock-buidl) records that its transfer agent can freeze and seize BUIDL on the chains it reads (Ethereum and Solana); it does not read BNB Chain or Avalanche.
Who can freeze or claw back
Ethereum: can freeze a holder, pause transfers, claw back, mint, change the code (allowlist unverified). A single key can freeze a holder. Owner key: a single key. A single key, through a contract, can change the code with no delay.
Solana: can freeze a holder, pause transfers, claw back, mint. A single key can freeze a holder and claw back tokens and pause transfers. A single key can change the code with no delay.
How it exits
Redeem with the issuer in its window. A client of Anchorage Digital Bank sends USDtb to the bank and receives dollars at $1 a token, less the fees in the bank’s Covered Stablecoin Fee Schedule, which is not public. The bank processes requests with commercially reasonable efforts and may refuse, suspend, or limit any of them, including for liquidity management. The terms name no cutoff and no settlement time. Settles in USD.

This file replaced an earlier record on 2026-09-24. Superseded the day it was published: the file called USDtb issuer direct and a note, the nearest values the file type then had, so the page said the chain is a securityholder file. USDtb is a bank’s promise to pay $1 and has no securityholder file. The file type gained the claim model issuer liability and the kind payment stablecoin, and the file now uses both. Terms, contracts, and readings are unchanged. Superseded records.

Who may buy, hold, transfer, and redeem

Each answer rests on the issuer’s own words, quoted from the document named under it. Ketju re-reads each document and records whether the words are still there. Where the documents say nothing, the row says so.

What the holder owns

A $1 claim on Anchorage Digital Bank, the sole issuer and the sole party that owes it; not a share of BUIDL.

“ADB remains the sole issuer of, and the sole obligor for, every Series of Covered Stablecoins within the meaning of the GENIUS Act, 12 U.S.C. § 5901 et seq., even when ADB engages one or more Service Providers to perform operational or administrative functions.”

What the holder owns

A holder who is not a bank client has no contract rights against the bank, only what the law gives.

“Non-Clients have no contractual relationship with ADB under these Terms and no enforceable rights against ADB in respect of Covered Stablecoins, except as may arise under applicable law.”

Anchorage Digital Bank, N.A. Covered Stablecoin Terms (effective 13 October 2025) · 1. Scope and Applicability, Non-Clients · words found 2026-09-24

What the holder owns

The reserve’s income, including BUIDL’s dividends, goes to the bank, not to holders.

“All income, gains, or other returns realized on the Covered Stablecoin Reserve beyond the amounts necessary to maintain reserves sufficient to back outstanding Covered Stablecoins on at least a one-to-one basis constitute fiduciary compensation to ADB for administering the Covered Stablecoin Reserve Trust.”

Who may hold it

Anyone may hold it; a holder who is not a bank client is simply not the bank’s customer.

“Persons who hold Covered Stablecoins but are not Clients (“Non-Clients”) are not customers of ADB.”

Who it may be transferred to

Any wallet the bank has not blocked may send and receive it.

How a holder redeems

Only clients redeem, at $1 less fees in a schedule the bank has not published.

“Covered Stablecoins presented for redemption by Clients are redeemed at the Par Value for the applicable Series, net of any applicable fees disclosed in the Covered Stablecoin Fee Schedule.”

How a holder redeems

The bank may refuse, suspend, or limit any redemption.

“ADB may refuse, suspend, or limit any redemption request in its discretion, including for reasons such as incomplete verification, suspected fraud or illicit activity, risk management concerns, operational limitations, liquidity management, regulatory restrictions, unavailability of a particular Series, or violation of the Master Account Agreement or these Terms.”

Who keeps the official record

No transfer agent; the token carries its rights, so the chain is the record of who holds them.

“A transfer of Covered Stablecoins transfers all rights associated with those Covered Stablecoins to the recipient.”

What the issuer says it can freeze or take back

The bank may freeze, block, or seize any holder’s USDtb, client or not.

“ADB may freeze, block, seize, or otherwise restrict Covered Stablecoins where required by court orders, subpoenas, regulatory directives, or law enforcement requests, or where ADB determines that a transfer violates, or is likely to violate, applicable law or regulation.”

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.

EDGAR has no Form D for USDtb. The issuer, Anchorage Digital Bank, N.A., is an OCC-chartered bank that offers USDtb as a payment stablecoin and claims no securities exemption. The only Form D from its parent, Anchor Labs, Inc. (CIK 1783914), is the parent’s own 2019 equity raise; Pallas (BVI) Ltd, the issuer before October 2025, has no EDGAR filer record; Ethena, Inc. of Brooklyn (CIK 1836631) filed its last Form D in 2022, two years before USDtb launched. Searched 2026-09-24 for “USDtb”, “Anchorage Digital Bank”, “Anchor Labs”, “Pallas (BVI)”, “Ethena”.

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.

ChainFreeze a holderPauseClaw backGate holdersChange the codeKeys held by

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.

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 its one-dollar value. Every document quoted above is re-read too, and a quote that leaves its document reopens the file. 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.
