Why buying USDB in a non-custodial wallet is safer

When you buy USDB on an exchange, the exchange holds your funds. If the exchange is hacked, freezes withdrawals, or goes bankrupt, your USDB is at risk. Tangem ensures that doesn't happen to you. When you buy USDB, our integrated provider sends it directly to your wallet's public address.

  • No. Tangem lets you buy USDB directly in the app using Apple Pay, Google Pay, and more payment options. You never need to create an exchange account or go through a separate verification process to get started.

  • No. Tangem is fully self-custodial. Your USDB is stored on the secure chip inside your Tangem card, and only you hold the private keys. Tangem never has access to your funds.

  • Most purchases complete within a few minutes. Once the payment is approved by the provider, your USDB is delivered straight to your Tangem Wallet.
