Enable multi-currency settlement on your Adyen merchant account and configure bank accounts in the settlement currencies you want to receive
At checkout, present pricing in the cardholder's local currency using Dynamic Currency Conversion if applicable, or charge in your base currency and let the cardholder's issuer handle conversion
In the authorization request, set the transaction currency to the cardholder's local currency; Adyen will handle conversion to your settlement currency at the agreed FX rate
Review your FX rate agreement with Adyen: understand whether you receive a guaranteed rate, a market rate, or an end-of-day batch rate
Map each settlement record in the settlement detail report to its transaction currency counterpart to reconcile FX differences in your accounting system
Set up currency-specific GL accounts to record FX gains and losses separately from transaction revenue
Known gotchas
Dynamic Currency Conversion (DCC) requires explicit cardholder consent and clear disclosure of the exchange rate and fee; failure to disclose properly violates network rules and local regulations
FX rates at authorization time may differ from rates at settlement time (for delayed captures); the difference becomes an FX gain or loss that must be accounted for
Not all currencies are settleable directly; some currencies must be settled in a proxy currency (e.g., USD) and the conversion is handled by your bank, not the acquirer
