HTX is in serious trouble. The crypto exchange now faces sanctions from both the European Union and the United Kingdom’s Foreign Commonwealth & Development Office — and that’s just the start of its problems.
TRM Labs tracked what happened next. After the sanctions landed, HTX began rotating through blockchain addresses at speed, a pattern that TRM Labs said looks like a deliberate attempt to obscure where its holdings actually sit. Not a great look for an exchange already under international pressure.
The stETH Moves That Raised Red Flags
The numbers are hard to ignore. Before the sanctions-related changes, HTX’s proof-of-reserves listed several specific addresses. On May 1, one of those addresses held 71,853.22 stETH — worth roughly $135 million at the time. By May 30, that stETH was gone from the original address, moved to a second address, then transferred again, and again, eventually landing in addresses that Etherscan tags as linked to Poloniex.
One address in particular stands out. The wallet now labeled “Poloniex 9” on Etherscan was previously tagged as “Justin Sun 4.” That’s a pretty significant detail. It means funds moving through HTX’s reserve addresses ended up in a wallet once associated directly with Justin Sun before it was relabeled under the Poloniex umbrella. Whether that reflects deliberate mixing of reserves or something more mundane, it’s unclear — but the chain of custody looks murky at best.
And it gets more complicated. HTX didn’t just move funds around quietly. It also changed its proof-of-reserves structure, creating a new category called “ThirdParty” to signal that certain assets are held in custody by outside parties. HTX says users can verify those funds directly with the custodians. But HTX hasn’t named a single one of those custodians. Not one.
Poloniex’s Shadow Over HTX’s Books
Poloniex isn’t a minor player in this story. A significant chunk of HTX’s Bitcoin holdings appears to be tokenized and sitting under Poloniex’s control — worth hundreds of millions of dollars, per the available information. That’s a substantial portion of HTX’s reserves effectively parked at a separate exchange.
Poloniex declined to disclose the specific Bitcoin addresses holding those assets. So you’ve got hundreds of millions in tokenized Bitcoin, managed by an exchange that won’t say exactly where it is, for another exchange that won’t name its custodians. That’s a lot of opacity stacked on top of more opacity.
The Poloniex connection matters because it keeps appearing throughout HTX’s transaction history. It’s not a one-off. The stETH trail, the tokenized Bitcoin holdings, the relabeled wallet addresses — Poloniex shows up repeatedly, and the relationship between the two platforms seems deeper than a standard custodial arrangement. What that relationship actually looks like on paper, no one’s saying.
HTX’s broader reliance on Poloniex for asset management raises questions that probably won’t go away on their own. If HTX’s reserves are partly held by Poloniex, and Poloniex won’t disclose the addresses, then the “ThirdParty” category in HTX’s proof-of-reserves is basically unverifiable for anyone on the outside. HTX says trust the custodians. But without knowing who the custodians are, that’s a tough ask.
What Transparency Gaps Mean for Users
Proof-of-reserves became a major topic across the crypto industry after the FTX collapse in 2022, when it became painfully obvious that exchange balance sheets weren’t always what they seemed. The whole point of proof-of-reserves is to give users some confidence that funds are actually there. When an exchange starts moving assets through multiple addresses right after sanctions hit, then restructures its reserve categories without naming custodians, the proof-of-reserves system can’t really do its job.
HTX’s situation is probably going to stay murky for a while. The sanctions from the EU and UK create real pressure, but they don’t automatically force disclosure. And as long as Poloniex won’t name the Bitcoin addresses and HTX won’t name its third-party custodians, the gap between what HTX claims and what anyone can independently verify stays wide open.
Stakeholders trying to get a clear read on HTX’s actual financial position are basically working with incomplete information. The stETH moved. The addresses changed labels. The custodians are unnamed. And Poloniex, which seems to sit at the center of a lot of this, isn’t talking.
The 71,853.22 stETH that started at one address on May 1 eventually landed in Poloniex-linked wallets by the end of May — and the full picture of why, and what it means for HTX’s reserve integrity, hasn’t come into focus yet.
