A crypto advocacy group, The Digital Chamber, is urging the US Comptroller to defend approvals of crypto company charters after Senator Elizabeth Warren accused the regulator of breaking banking laws.

The Digital Chamber, a leading crypto advocacy organization, has called on the Office of the Comptroller of the Currency to stand by its decisions. This comes after Senator Elizabeth Warren claimed that approving special charters for crypto firms might break US banking rules. The group wants the regulator to protect these applications and explain why they follow the law. The move highlights ongoing tensions between crypto businesses and lawmakers in Washington. Supporters say such charters help bring digital assets into the mainstream financial system safely.
