A dispute between a major exchange and a politically connected stablecoin issuer turned into a delisting in under 48 hours. Here is how HTX moved from suspending trading pairs to wiping USD1 off its books.
What Happened: A 48-Hour Escalation from Freeze to Full Delisting
HTX delisted USD1, the dollar-pegged stablecoin tied to the Trump family's World Liberty Financial (WLFI), after accusing the WLFI team of unilaterally freezing specific HTX on-chain addresses . The sequence ran from a June 5 trading-pair suspension to a complete USD1 removal by June 7, with affected balances auto-converted to Tether's USDT at 1:1 .
Quick Answer: HTX delisted the WLFI-linked USD1 stablecoin on June 7, 2026, after alleging WLFI froze certain HTX on-chain addresses following a sanctions-compliance review. The full delisting took effect at 03:00 UTC, and remaining USD1 user balances were automatically converted to USDT at a 1:1 ratio.
The operational timeline was consistent across reporting. On June 5, HTX first suspended four trading pairs — WLFI/USDT, USD1/USDT, BTC/USD1, and ETH/USD1 — citing user protection, market fairness, and reduced systemic risk .
| Time (UTC) | Action |
|---|---|
| Jun 5, 13:00 | HTX suspends WLFI/USDT, USD1/USDT, BTC/USD1, ETH/USD1 |
| Jun 6 (first notice) | Freeze dispute and pair suspensions explained |
| Jun 6 (~1 hr later, second notice) | USD1 delisting announced |
| Jun 7, 03:00 | Full USD1 delisting takes effect; balances convert to USDT 1:1 |
On June 6, HTX issued two notices within one hour accusing WLFI of freezing specific HTX addresses after a "sanctions-compliance review" that restricted on-chain circulation of certain WLFI assets . HTX said USD1 deposits would stop and conversion details would follow separately .
Crucially, WLFI had not publicly confirmed the freeze as of reporting. Its June 3 compliance notice warned only that transactions involving sanctioned persons, entities, or associated wallet addresses "may face enhanced review, rejection, restrictions, or other compliance actions" .
Why USD1 Has a Freeze Switch — and Who Can Pull It
USD1 carries a freeze switch because it is a custodian-issued stablecoin, not a decentralized one. The token is issued and redeemed by BitGo Bank & Trust, N.A., which also holds the reserves, while World Liberty Financial, Inc. and SC Financial Technologies, LLC own the USD1 brand and provide certain services . That structure means freeze authority sits with the issuer and brand parties, not with token holders.
USD1's own risk disclosures spell this out. They grant BitGo — and, in some clauses, WLFI Parties — authority to deny access to specific USD1 addresses, freeze associated tokens temporarily or permanently, and block transfers to and from any on-chain address . These controls are standard for regulated, fully-reserved stablecoins, but they leave centralized counterparty risk that HTX's account holders are now confronting directly.
The token's backing was not the question here. BitGo's April 2026 reserve attestation, dated May 28, 2026, reported approximately $4.5 billion in USD1 outstanding against equivalent redemption assets as of April 30, 2026, with reserves meeting or slightly exceeding the outstanding supply, and listed zero access-restricted or time-locked tokens on the report dates, before the HTX dispute . The dispute is about who can press the freeze switch, not whether dollars sit behind the peg.
HTX argues the action lacked any valid basis. The exchange called the freeze "conducted without sufficient prior communication, adequate contractual or legal grounds, transparent disclosure, or adherence to due process" .
"The frozen digital assets are not assets belonging to any sanctioned entity, but rather assets legally purchased and owned by individual users," — an HTX spokesperson, via @HTX_Molly on X (source: NullTX).
World Liberty Financial, for its part, left the central question open. As of the delisting it had not publicly confirmed whether the HTX addresses were frozen or by whom, offering no incident-specific explanation beyond its earlier general compliance language . That silence is itself a data point: the freeze capability is real and documented, but accountability for using it remains contested.
The Sanctions Layer: UK Designation and the HTX Entity Dispute
The freeze did not happen in a vacuum — it traces back to a UK sanctions action. On May 26, 2026, the UK designated HUOBI GLOBAL S.A. under its Russia sanctions regime, with the Unique ID RUS3619 . The notice lists name variations including HTX (formerly Huobi), HTX Exchange, and Huobi Global Limited, gives the website as htx.com, and states the Secretary of State had reasonable grounds to suspect the entity supported the Government of Russia by providing financial services or resources to A7 Limited Liability Company and Garantex Europe OU — with alleged links to more than $1.5 billion in transactions tied to sanctions circumvention .
The designation imposes an asset freeze and obliges anyone with reasonable cause to suspect they hold funds of a designated person to freeze them, not make them available without a licence, and report to OFSI. The scope is where it gets contested. Two official sources point in opposite directions:
- OFSI's position: its FAQ, updated May 29, 2026, states the designation applies to the HTX cryptocurrency exchange itself, because OFSI considers HTX subject to UK financial sanctions due to ownership by Huobi under regulation 7(2)(a) of the Russia Regulations .
- HTX's position: the exchange maintains that Huobi Global S.A. is a distinct legal entity from the online HTX exchange, and that the designation should not affect HTX's global operations or user funds .
That unresolved entity-scope question sits directly beneath the WLFI freeze. If OFSI's reading holds, a counterparty freezing HTX-linked addresses could frame it as defensible compliance; if HTX's reading holds, the same action looks closer to overreach against a non-designated operator. HTX rejects the framing outright. "These frozen digital assets are not assets belonging to any sanctioned entity," an HTX spokesperson said via @HTX_Molly on X, describing them instead as assets "legally purchased and owned by individual users" . Until regulators or courts settle whether the designation reaches the exchange, the legitimacy of the freeze stays open.
What to Watch: Sun vs. WLFI, and the Broader Stablecoin Governance Signal
The legal fight predates this delisting. Justin Sun sued World Liberty Financial in April 2026, alleging the WLFI smart contract holds a hidden "backdoor" that lets the team freeze investor tokens without notice or consent . WLFI countersued in May 2026 for defamation and for breaching terms tied to the WLFI token sale .
This is also the second time WLFI has used its on-chain freeze capability against Sun-linked addresses. The first came in September 2025, after Sun moved roughly $9 million in WLFI tokens between addresses, including HTX, and the project blacklisted his personal wallet . The pattern matters more than any single freeze: it shows the control is operational, not theoretical.
That is the broader signal for traders. USD1 was not a fringe token — BitGo's attestation showed about $4.5 billion redeemable USD1 outstanding as of April 30, 2026, deployed across 11 blockchain networks . The HTX removal tests whether other centralized exchanges now reassess custody and listing risk for politically connected, issuer-freezable stablecoins.
Several numbers remain undisclosed as of June 7, 2026, and they will define the real cost of the dispute :
- Affected wallet count — HTX has not published the frozen addresses or how many users are impacted.
- Total WLFI/USD1 exposure on HTX — no figure for trapped or restricted balances.
- Conversion completion timeline — HTX promised a 1:1 USDT conversion but gave no finish date or final distribution report.
The concrete takeaway: a $4.5 billion stablecoin just demonstrated that its issuer can wall off exchange addresses mid-feud. For retail traders, the lesson is to treat issuer-controlled freeze rights as a live counterparty variable — and to watch whether the Sun–WLFI litigation, or a regulator, forces those undisclosed numbers into the open.
Frequently asked questions
What happens to USD1 held on HTX after the delisting?
HTX said eligible USD1 balances remaining in user accounts are automatically converted to Tether's USDT at a 1:1 ratio and credited to spot trading accounts after conversion . The full delisting took effect at 03:00 UTC on June 7, 2026 (11:00 UTC+8), after which deposit and conversion services for USD1 were no longer supported . HTX stated that exact distribution and completion details would be announced separately, so no final timeline or distribution report has been published yet.
Did World Liberty Financial actually freeze HTX's addresses?
It is contested. HTX asserts yes, providing a timeline in which it suspended four trading pairs at 13:00 UTC on June 5, 2026 and accused the WLFI team of freezing specific on-chain addresses after "sanctions-compliance reviews" . World Liberty Financial has not publicly confirmed freezing the specific HTX addresses. WLFI had posted only a general June 3, 2026 sanctions-compliance notice warning that transactions involving sanctioned persons or associated wallets may face enhanced review, rejection, or restrictions .
Is HTX itself under sanctions?
This is the core dispute. On May 26, 2026, the UK designated HUOBI GLOBAL S.A. under its Russia sanctions regime (Unique ID RUS3619), alleging links to more than $1.5 billion in transactions tied to sanctions circumvention . OFSI's FAQ, updated May 29, 2026, says the designation applies to the HTX cryptocurrency exchange due to Huobi ownership under regulation 7(2)(a) . HTX disputes this, maintaining that Huobi Global S.A. is a distinct legal entity from the exchange and that user funds are unaffected.
Can any stablecoin freeze my tokens without warning?
Many issuer-controlled stablecoins include freeze clauses, and USD1 is explicit about this. Its risk disclosures grant BitGo — and in some clauses BitGo or WLFI Parties — authority to deny access to certain USD1 addresses, freeze associated USD1 temporarily or permanently, and block transfers to and from any on-chain address . This kind of centralized control is standard in fiat-backed stablecoin design, but the exact rights and who holds them vary by issuer. Self-custody of a token does not remove an issuer's on-chain freeze capability.
Is USD1 still safe to hold on other exchanges?
The HTX incident is a counterparty and compliance dispute, not a reserve shortfall. BitGo's April 2026 attestation, dated May 28, 2026, showed approximately $4.5 billion in redeemable USD1 outstanding against equivalent redemption assets as of April 30, 2026, with reserves meeting or exceeding the outstanding supply, and reported no access-restricted or time-locked USD1 tokens on the report dates . Backing was full and 1:1 at that date. Still, the freeze capability applies regardless of which exchange holds the token, so treat issuer freeze rights as a live counterparty variable.
