On January 9, PANews reported that Eric.eth, a co-author of EIP-1559, shared information on the X platform that the Biden administration's Commodity Futures Trading Commission (CFTC) is issuing a subpoena to Coinbase regarding the Polymarket case, requesting Coinbase to provide information related to certain customers. In an email sent to customers, Coinbase stated: "You do not need to take any action, but Coinbase may need to send information related to your account to the Commodity Futures Trading Commission pursuant to the subpoena, unless Coinbase formally receives a motion to withdraw the subpoena or other legal documents preventing Coinbase from sharing such information before the end of business on January 15, 2025."
