For payments via the Request Finance webapp
For conversions between crypto and fiat or one cryptocurrency and another, we're using several providers:
Where available, we use rates from Chainlink (https://chain.link/)
If Chainlink is not available, we use rates from Cryptocompare (https://www.cryptocompare.com/)
For Crypto-to-Fiat payments, rates depend on the currency
If "1:1 Stablecoin Conversion" is enabled in Product Settings, then a fixed rate between fiat and stablecoins is applied
Good to know: Request and its partners protect you against depegs (devaluations of stablecoins so that the exchange rate isn't close to 1:1). Learn more
For card payments
We use Mastercard exchange rates (https://www.mastercard.com/global/en/personal/get-support/currency-exchange-rate-converter.html)
