Griff Green, an Arbitrum Security Council member, said Tether actively freezes stolen assets while Circle does not, framing the difference as a contrast in how the two stablecoin issuers respond to illicit crypto activity.
Griff Green, identified in the source as an Arbitrum Security Council member, publicly criticized Circle and said Tether takes a more active role in freezing hacker-controlled funds. His comment presents a sharp contrast between the two major stablecoin issuers and highlights a recurring issue in crypto: whether centralized token issuers should intervene by blocking or freezing assets linked to theft. In practice, stablecoin freezing is possible because issuers such as Tether and Circle can control token contracts or redemption access, making compliance and asset recovery a significant part of the market’s security and regulatory debate.
