The exchange process allows users to buy crypto from the Immutable X platform using a credit card. There's no gas price for purchases, only a Moonpay transaction fee.

The deposit happens directly on L2 via the transfer from Moonpay accounts.

The amount, fee and currency are selected within the Moonpay widget, and are under user's control. There's a minimal deposit amount of $20USD.

The current available cryptos are:

  • USDC
  • ETH
  • IMX
  • GODS

❗️

Exchange requires authenticated user

Link.fiatToCrypto({}) should only be called when user is authenticated and logged in, otherwise it will require user to reconnect

To initialise the exchange process with an option to choose any available currency, a developer needs to call the exchange function:

await link.fiatToCrypto({})

This displays the Link UI with loaded Moonpay widget:

To initialize the exchange process for a specific currency:

await link.fiatToCrypto({cryptoCurrencies: ['ETH']})
