Circle, Tether freezes over $65M in assets transferred from Multichain
Stablecoin issuers Circle and Tether have frozen over $65 million in assets tied to the suspected exploit of cross-chain router protocol Multichain. The move follows unexplained large outflows from the Multichain MPC bridge on July 6.
