Tether Blacklists Ethereum Address Linked to Multichain Hack

• Stablecoin issuer Tether has frozen an Ethereum address holding over $715,000 worth of USDT, according to data from block explorer site Etherscan.
• The address traces back to hackers who stole $3 million in cryptocurrency on the cross-chain bridge Multichain nearly a month ago, according to Etherscan's labeling of transactions involving the wallet as well as a CoinDesk analysis.
• Whoever controls the address will not be able to move funds so long as they are frozen.
• The hack on Multichain was made possible by a security vulnerability, which the team behind the project warned users about in January.
• Tether did not immediately respond to a request for comment
• Three addresses with over $160 million in USDT were frozen in mid-January at the request of law enforcement.
• Tether, which issues tokens on several blockchains, began blacklisting addresses following a 2017 breach in which the firm said $30 million of USDT was stolen.
