Coinbase has officially received full US federal approval to operate as a national trust bank, marking a significant regulatory milestone for the largest cryptocurrency exchange in the United States. The approval grants Coinbase a federal banking charter, positioning it among a select group of institutions authorized to provide trust services under US federal oversight. The national trust bank charter enables Coinbase to custody digital assets and offer trust services under a unified federal framework, reducing reliance on state-by-state licensing. This development strengthens Coinbase's regulatory standing as US crypto legislation continues to evolve.
