Empiric supports specific pairs that are listed and traded by our data partners. We also support a broader concept of currencies (each pair is a price of the quote currency in terms of the base currency). For pairs not listed, their price can be deduced by "hopping" using pairs that are listed, e.g. we can combine ETH/USD and BTC/USD to get a ETH/BTC feed.
The following asset pairs are officially supported by Empiric. More are added every week, so just reach out on Twitter or Discord if you have a specific one you need.
The pair_id is calculated by utf-8 encoding the uppercased string (e.g. bytes32("BTC/USD")) and used to refer to specific feeds on-chain.
