Coinbase received final approval from the Office of the Comptroller of the Currency (OCC) to establish Coinbase National Trust Company, advancing its digital-asset custody business beyond an earlier conditional clearance. The OCC’s licensing register lists the charter as effective Nov. 6, following an approval entry dated April 2, while Coinbase announced the final clearance on Nov. 9 and said the regulator approved its application the previous Friday. The national trust company gives Coinbase a federal regulatory framework for expanding custody services that safeguard customers’ digital assets. Separately, lawmakers are seeking records on crypto trust-charter approvals, compliance and possible dealings with people tied to President Donald Trump’s administration. Sen. Elizabeth Warren requested documents related to at least nine approvals, including Coinbase’s conditional approval, while Sen. Richard Blumenthal renewed demands for records from Binance, Tether and two Trump-linked ventures, with a Jan. 4, 2027, deadline for voluntary production.
