HTX Packs $1.3B Into a Mystery Suitcase as Sanctions Spook the Custody Game 🧳

HTX, the crypto exchange controlled by Justin Sun, has shifted roughly $1.3 billion in reserve assets to an undisclosed third party, according to the platform's latest Proof of Reserves report. The reallocation covers 1,719 BTC, equal to about 8% of its reported 20,922 BTC holdings, alongside 76,515 ETH from its Ethereum reserves. The exchange also moved 99% of its $238 million USDC stash and $819 million of its $906 million USDT stockpile to the same custodian, with additional tokens rounding out the $1.3 billion total.

The reshuffle follows the United Kingdom's decision to sanction HTX over allegations that the venue helped Russian entities move capital. Prominent security researcher Taylor Monahan framed the custody transfer in stark terms: "Risk has changed for HTX due to the sanctions, which means that govt overreach is now a bigger threat than, say, getting hacked." Onchain investigator ZachXBT echoed that view, calling the U.K. measures "a bit of an overreach" and arguing authorities overlooked a $1.2 billion "legit laundering case" while targeting innocent Asian retail users on HTX.

Compliance pressure is rippling outward. Binance, Bybit, OKX and Hyperliquid have all begun blocking wallet addresses that show any transfer history linked to HTX, a pattern community members say effectively sweeps up the exchange's entire user base, guilty or not. Supporters of the bans argue that platforms refusing to act risk drawing their own sanctions, which could result in funds being frozen wholesale until compliance issues are resolved.

HTX has maintained that it still backs user assets 1:1 and pointed to its second-place ranking in capital netflows over the past week despite the U.K. action. The exchange has not publicly named the third-party custodian now holding the bulk of its reported reserves, and it remains unclear how the new custody arrangement will interact with the ongoing address-level restrictions imposed by peer venues.
