Oi, Ygor! São muito fáceis de fazer! Você precisa cadastrar uma "chave". Pode ser email, cpf, cnpj. Alguns bancos tradicionais posseum pix dentro do app. Também há bancos online, que eu prefiro. By the way, I'm brazilian and I would love to help brazilian portuguese admirers like you to keep practicing portuguese through some conversation lessons! They will be some relaxed and fun lessons and still you'll be learning a lot, receiving corrections when welcome, off course, and getting in touch with some basic grammar, pronunciation, spelling and vocabulary!In addition to Brazilian culture, of course! Feel free to visit my profile! It will be a pleasure to meet you and provide us with a pleasant cultural exchange! <3 Um abraço! See ya!
