Polemix supports two types of payment methods:

• Crypto Wallets: You can use them to purchase POSUs directly with ETH through the connected wallet.
• Credit Card: We collaborate with wert.io to enable credit card payments. Wert helps convert your fiat currency to cryptocurrency, which is used to purchase a POSU. A credit card processing fee will apply to all credit card purchases, and 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 this data; Wert requires it for security purposes.
