# Bank Accounts

> Register your existing fiat bank account to enable transfers across supported rails and currencies.

A bank account in Pythas is a registration of your existing fiat bank account. Pythas does not open or manage bank accounts — it registers an account you already hold so it can be used as the source or destination for fiat transfers.

<Info>
  You must register at least one bank account before initiating a transfer that involves fiat currency. The account must already exist at your bank before registration.
