Craft 3 - Matrix Block for currentUser
Well, many tries later, I found a way to do it.

{% for block in currentUser.certificado %}
&lt;div&gt;
    &lt;h3&gt;{{ block.nomeDoCertificado }}&lt;/h3&gt;
    &lt;h3&gt;{{ block.curso[0] }}&lt;/h3&gt;
    &lt;a href="{{ block.certificado[0].url }}" target="_blank"&gt;{{ block.nomeDoCertificado }}&lt;/a&gt;
&lt;/div&gt;
{% endfor %}


It is as simple as that :)
