Curbing Officials' Income and Nondisclosure (COIN) Act

The COIN Act proposes a broad set of ethics and financial safeguards to curb perceived financial exploitation by federal public office holders and their immediate families with respect to digital assets. It creates a new subchapter in Title 5 that bans certain prohibited financial transactions involving cryptocurrencies and related digital assets by covered individuals during service (and in specified pre/post periods), imposes civil and criminal penalties for violations, and expands ethics reporting to capture crypto holdings above a threshold. It also requires a certification regime for permitted payment stablecoin issuers, and directs a GAO review to update ethics and enforcement frameworks to cover digital assets. Overall, the bill aims to reduce conflicts of interest and insider advantages that could arise from involvement with digital asset markets.
