Gemini Can Freeze its USD-Pegged Cryptocurrency at Any Time | CCN
"Writing on tech publication Good Audience, blockchain researcher Alex Lebed performs a code review of the Gemini dollar smart contract, finding that, contrary to the ethos and technical specifications of decentralized cryptocurrencies like bitcoin, GUSD includes a provision that allows its “custodian” — namely Gemini — to freeze any account. Lebed — who, in full disclosure, is also attached to a separate stablecoin project — further notes that GUSD uses an ERC20Proxy contract that gives Gemini, as the custodian, the ability to upgrade the contract once every 48 hours, giving it among a myriad of other things the power to simultaneously render all tokens non-transferable."
