Tether and Circle Freeze $2.49M as Iranian Exchange Wallex Rushes Funds to BSC
Tether and Circle simultaneously blacklisted an Ethereum hot wallet belonging to Iranian crypto exchange Wallex, freezing stablecoins while the platform was actively moving assets across chains. Blockchain investigator ZachXBT flagged the incident on March 25, revealing that the dual freeze had locked approximately $2.49 million in stablecoin assets .
The Freeze: What Happened
The blacklist targeted address 0x6926…43df, which held roughly $117,000 in Tether (USDT), USD Coin (USDC), and smaller tokens at the time of the freeze. However, the broader operation—an attempted cross-chain consolidation by Wallex—resulted in a much larger sum being trapped .
Hours before the blacklist, Wallex reportedly began consolidating crypto from multiple hot wallets on Tron and Ethereum into BNB Smart Chain (BSC) using several cross-chain bridges. The operation partially succeeded. Approximately $2.49 million in Binance-Peg BSC-USD landed at a separate BSC address, 0xf945…ccdd .
That address has since logged only three small incoming BNB transactions for gas fees. No outflows have occurred. The funds remain completely idle, frozen in place as the stablecoin issuers acted to block the associated Ethereum wallet .
A Rare Coordinated Action
The dual freeze is unusual. Both Tether and Circle—the two largest stablecoin issuers—acted within the same window, suggesting coordinated compliance enforcement. While each company maintains its own blacklist policies, simultaneous action against the same entity indicates that both received similar intelligence or regulatory pressure .
Wallex has not been formally designated by the U.S. Treasury’s Office of Foreign Assets Control (OFAC). However, all crypto activity tied to Iran is subject to broad sanctions exposure, and stablecoin issuers have increasingly taken proactive measures to block addresses associated with sanctioned entities or high-risk jurisdictions .
Broader Crackdown on Iranian Crypto Flows
The incident fits a pattern of escalating stablecoin enforcement against Iran-linked platforms. 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 Corps. Those sanctions marked a significant escalation in U.S. efforts to choke off Iranian access to cryptocurrency markets .
Tether alone has blacklisted over $3.3 billion in USDT across more than 7,000 wallets since 2023. The company has consistently stated that it cooperates with global law enforcement and complies with sanctions regimes. Circle has taken similar actions, though its cumulative freeze volume is smaller given USDC’s more limited circulation in higher-risk jurisdictions .
Growing Pressure on Iranian Exchanges
Iranian crypto exchanges face mounting pressure. Iran’s central bank ordered major platforms, including Wallex and Nobitex, to suspend USDT-toman trading earlier in March. The move was intended to slow capital flight following U.S. and Israeli military strikes that escalated regional tensions .
Wallex has not issued a public statement regarding the freeze. Its website remains operational, and the exchange continues to advertise services to Iranian users. However, the frozen funds on BSC have not moved, and additional wallets tied to the exchange could face similar action if flagged by compliance systems .
What This Means for Stablecoin Users
The simultaneous freeze underscores the growing power of stablecoin issuers to control on-chain assets. Unlike decentralized protocols, USDT and USDC are centrally issued tokens with built-in blacklist functionality. While this provides compliance tools for law enforcement, it also highlights the inherent trade-off between stability and decentralization .
For users in high-risk jurisdictions, the incident serves as a reminder that stablecoin holdings can be frozen at the issuer’s discretion. The coordinated action against Wallex—an exchange not formally sanctioned—suggests that proactive compliance monitoring is increasingly common .
The $2.49 million on BSC remains idle. Whether it will eventually be released or permanently frozen depends on ongoing investigations and Wallex’s ability to demonstrate compliance with sanctions requirements .
