SEPA is a banking infrastructure layer and it is not consumer focused. Also, only ~60% of European banks adopted it. While Pix was mandatory for all banks to adopt and 80% of Brazilian population already used it.

All banks in Euro (currency) countries have adopted SEPA. You might be thinking of SEPA Instant Payments, which is more recent and adotopion isn't universal yet.

In Spain we have Bizum. You can send money to any phone number. It's instand and, as I understand, it works on top of SEPA.

Never understood why it’s tied to a phone number. I don’t like to leak mine just for silly payments.

Pix resolved this by allowing email, phone number, tax ID or random generated key as an identifier.
