No, you only need one bank account, any bank account. During our sign-up process, you will specify a single bank account as your home currency account, and all of your collected payments will be paid into that account in your home currency. You may add multiple bank accounts in the same country to switch where your payments get debited and deposited.
borderless also provides multicurrency balances where you can hold, exchange and receive international currencies to. When withdrawing to your bank or get paid, borderless will deliver funds to your bank account in your local currency where available.
