Griff Green, a member of the Arbitrum Security Council, has accused Circle of failing to block hackers’ funds, unlike its competitor Tether. He argues that the leadership of USDC prioritizes profit over security.

Green noted that Tether actively freezes assets linked to North Korean hackers and has already recovered over $70 million. He attributed this to the company’s roots, stating it was founded by “crypto-oriented” individuals who share the industry’s values.
He described Circle as an entity akin to Goldman Sachs, suggesting that the company is solely interested in financial metrics and ignores thefts unless countering them yields obvious benefits.
“If you have the ability to solve a problem, you are responsible for it. Circle does nothing, while Tether blocks North Korean accounts left and right,” he stated.
As a form of pressure, Green urged users to sell USDC. He believes only market signals can compel the company to seriously combat hackers who “destroy investors’ portfolios and the entire world.”
In April, investors of Drift Protocol filed a class-action lawsuit against Circle. The plaintiffs accused the company of aiding hackers and negligence.
