Understanding BaseCurrency and SettledCurrency in Pay-In Requests

The baseCurrency represents the currency in which the merchant expects to receive the payment, while the settledCurrency refers to the currency in which the transaction is processed and settled.

---

Example 1:

A merchant sells a pair of shoes on an e-commerce website, priced at $100. The merchant accepts payments in cryptocurrency, and the customer chooses to pay using DAI.

• baseCurrency: USD (the currency the merchant prices the shoes in)

• settledCurrency: DAI (on Binance Smart Chain or another supported network)

In this case, the merchant expects $100 in USD, but the transaction will be processed in DAI on the BSC network. The merchant will receive the equivalent amount of DAI, calculated automatically by Tylt based on real-time spot rates at the time of the transaction request.

---

Example 2:

The baseCurrency doesn't have to be a fiat currency (USD, GBP, EUR, etc.). It can also be a cryptocurrency.

For instance, a merchant providing consulting services charges $100 in USDT.

• If the customer chooses to pay in USDT, both the baseCurrency and settledCurrency will be USDT.

• If the customer opts to pay in DAI, the baseCurrency will be USDT, and the settledCurrency will be DAI.

This scenario shows that both the baseCurrency and settledCurrency can be cryptocurrencies, and Tylt will handle the correct conversion at the moment of the transaction using real-time rates.

Important Notes:

The baseCurrency can be either a supported fiat or cryptocurrency. The settledCurrency will always be a cryptocurrency.
