Stablecoin Sheriffs Slap Freeze Ray on Iranian Exchange: Wallex Gets Iced

The stablecoin sheriffs are back in town. Tether and Circle have reportedly put the deep freeze on funds tied to the Iranian crypto exchange Wallex. The platforms zeroed in on a specific Ethereum wallet, effectively turning about $117,000 in USDT and USDC into digital popsicles.

The naughty-list wallet (0x6926…43df) was holding the stablecoins alongside a few other, less significant tokens. This move didn't just lock the funds; it also put a hard stop on the exchange's ability to bridge those assets elsewhere—a classic case of "not your keys, not your cross-chain liquidity." Roughly $2.49 million had been shuffled into wallets that later got iced, with zero funds managing to escape after the freeze hit.

Interestingly, Wallex itself hasn't been officially sanctioned by the OFAC crypto cops. The exchange's website is still up and running, proving this was a targeted wallet takedown, not a full-platform rug pull. The $2.49 million that made it to Binance Smart Chain is still sitting there, untouched and probably feeling a bit left out.

This coordinated chill-out session is part of a wider trend of getting tough on Iran-linked crypto rails. Tether, playing the role of the most proactive sheriff, has alone blacklisted over $3.3 billion in USDT across more than 7,000 wallets since 2023—that's a lot of digital assets sent to the penalty box.

The pressure isn't just coming from outside. Back in January 2026, OFAC sanctioned two UK-registered exchanges, Zedcex and Zedxion, for allegedly facilitating over $1 billion in transactions for Iran's Revolutionary Guard. Meanwhile, inside Iran, the local central bank is sweating too, recently asking big exchanges like Wallex and Nobitex to pause USDT-to-toman trades to try and plug capital flight—a classic case of trying to stop a leak with a band-aid.

The freeze was first flagged by the blockchain's favorite detective, ZachXBT, on March 25. The timing is, as they say in the biz, "interesting," coinciding with a separate report of a notable 17% drop in Circle's stock price. All this happened while Tether was busy prepping for its first-ever full audit of its USDT reserves—nothing like a little regulatory action to set the mood.
