Buying xDai with Portis via Carbon

Fiat to xDai onramp is easy to use and does not require KYC with low purchase amounts

xDai direct purchases (Carbon or Wyre) are currently under construction. Purchase Dai on the mainnet and use the Bridge UI to get xDai, or for an all-in-one exchange process you can use the Burner Wallet Exchange.

If your billing address is located in the U.S., Wyre is used to purchase xDai via the Portis wallet. If outside the US, you will use Carbon to buy xDai in the Portis wallet.

With Carbon, up to $250 in xDai may be purchased per day without KYC verification.
