How are display currencies calculated?

We support several key display currencies at the moment such as USD, EUR and ETH. This means that each visitor to Bancor can easily select the preferred display currency and view all information (token rates, 24 hours volume, liquidity depth, etc) in the display currency of their choosing.

Since the Bancor Protocol converts token prices into ETH, it must rely on external APIs (which provide the real-time price of ETH in fiat currencies) when displaying token prices in fiat currencies. In order to keep up to date with the rates, the Bancor Protocol uses two popular and reliable APIs:

1. CoinMarketCap - https://coinmarketcap.com/ 
2. CryptoCompare - https://www.cryptocompare.com/

Both APIs ensure our data is accurate, up to date and resilient to third-party issues. For instance, if one of the APIs goes down, the Bancor Protocol will fall back on the other API so the display currencies still work on the Bancor wallet.
