OnRamp

If you wish for your users to be able to pay for things in your game using cryptocurrencies, you'll find our Transak integration to be very helpful. Transak allows users to purchase a variety of cryptocurrencies on a variety of blockchains using their credit card using a user friendly web interface. Learn more about Transak here.

On-Ramp User Funds via Credit Card

To generate a link for your user's Transak on-ramping:

UTransakOnRamp* Transak = UTransakOnRamp::Init("UserWalletAddress");
FString OnRampLink = Transak->GetTransakLink("USD", "100", "BTC", "network1,network2", false);
// You can tailor the user experience by providing different default values for the parameters.

From here, you can open the OnRampLink using FPlatformProcess::LaunchURL. Alternatively, you can use:

UTransakOnRamp* Transak = UTransakOnRamp::Init("UserWalletAddress");
Transak->OpenTransakLink("USD", "100", "BTC", "network1,network2", false);
// This will automatically open the generated Transak On-Ramp link in the default web browser.

Check Supported Countries

To check the countries supported by Transak and learn about how they are supported, use the GetSupportedCountries method.

Transak->GetSupportedCountries(
    [](TArray<FSupportedCountry> SupportedCountries) {
        // Handle the supported countries, e.g., log their names
        for (const FSupportedCountry& Country : SupportedCountries) {
            UE_LOG(LogTemp, Log, TEXT("Country: %s"), *Country.CountryName);
        }
    },
    [](FSequenceError Error) {
        // Handle any errors that occur
        UE_LOG(LogTemp, Error, TEXT("Encountered error fetching supported countries from Transak: %s"), *Error.ErrorMessage);
    }
);

Using Transak from USequenceWallet

You can also access the Transak functionalities straight from USequenceWallet:

const TOptional<USequenceWallet*> WalletOptional = USequenceWallet::Get();
if (WalletOptional.IsSet() && WalletOptional.GetValue())
{
	USequenceWallet* Wallet = WalletOptional.GetValue();
    Wallet->GetSupportedTransakCountries(
    [](TArray<FSupportedCountry> SupportedCountries) {
        // Handle the supported countries, e.g., log their names
        for (const FSupportedCountry& Country : SupportedCountries) {
            UE_LOG(LogTemp, Log, TEXT("Country: %s"), *Country.CountryName);
        }
    },
    [](FSequenceError Error) {
        // Handle any errors that occur
        UE_LOG(LogTemp, Error, TEXT("Encountered error fetching supported countries from Transak: %s"), *Error.ErrorMessage);
    }
    );
}
// Open the Transak link in the default browser
Wallet->OpenTransakLink("USD", "100", "BTC", "network1,network2", false);
