If you live in a supported region, you can use Wert to buy POSUs with a credit or debit card on Polemix. Wert helps convert your fiat currency to cryptocurrency, which is used for purchasing a POSU. A credit card processing fee will be applied to all credit card purchases. Additionally, if you're using ETH, gas fees will also apply.

To use a credit card to purchase a POSU, you must first complete a verification process through Wert. Polemix does not store any of this data.
